Using a separated mdio bus driver with mvmdio, phy_detach on network device
removal will not stop the phy and finally lead to NULL pointer dereference
in mvmdio due to non-existent network device. Use phy_disconnect instead
to properly stop phy device from accessing network device prior removal of
the network device.

Note: I observed this behavior when removing a modular mv643xx_eth driver
after attaching it to a phy handled by (also modular) mvmdio. The mvmdio
conversion has been done in
commit c3a07134e6aa5b93a37f72ffa3d11fadf72bf757
("mv643xx_eth: convert to use the Marvell Orion MDIO driver")
and should go back any -stable version with that commit (propably only 3.9)
@David: I am not sure if the above description is sufficient for a -stable
patch, if you need more, like actual kernel failure, I am sure I can reproduce
it.

This connects to a phy node passed to the port device instead of probing

This adds device tree parsing support for the shared driver of mv643xx_eth.
As the bindings are slightly different from current PPC bindings new binding
documentation is also added. Following PPC-style device setup, the shared
driver now also adds port platform_devices and sets up port platform_data.
Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>
---
Note: Although different, device tree bindings are compatible with PPC
bindings. As I do not have access to any PPC platform using mv643xx_eth,
I leave conversion ("phy" vs "phy-handle") and compatible string name
up to PPC guys.
Due to hang reports for modular built mvmdio and mv643xx_eth, I have
tested module loading/unloading/reloading on CuBox (Dove) and Dockstar
(Kirkwood) without any issues for the whole patch set.
Changelog:
v3->v4:
- separation of independent patches (phy, of_mdio, devm)
- stand-alone device tree binding compatible to existing mv64x60 binding
- device node match for shared driver only
- device node registration for port drivers
- properly return -EPROBE_DEFER on missing of phy (Reported by Simon Baatz)
v2->v3:
- rebase on top of mv643xx_eth clean-ups
- do not reparse existing platform_data
- use managed devm_kzalloc for parsed platform_data
- use of_property_read_u32 where applicable
- add phy_node to platform_data
- use of_connect_phy if DT phy node was found
v1->v2:
- properly ifdef of_platform_bus_probe with CONFIG_OF
- handle of_platform_bus_probe errors and cleanup accordingly
- use of_property_read_u32 where applicable
- parse "duplex" and "speed" property in PHY-less configuration

+Marvell Orion/Discovery ethernet controller
+=============================================
+
+The Marvell Discovery ethernet controller can be found on Marvell Orion SoCs
+(Kirkwood, Dove, Orion5x, and Discovery Innovation) and as part of Marvell
+Discovery system controller chips (mv64[345]60).
+
+The Discovery ethernet controller is described with two levels of nodes. The
+first level describes the ethernet controller itself and the second level
+describes up to 3 ethernet port nodes within that controller. The reason for
+the multiple levels is that the port registers are interleaved within a single
+set of controller registers. Each port node describes port-specific properties.
+
+Note: The above separation is only true for Discovery system controllers.
+For Orion SoCs we stick to the separation, although there each controller has
+only one port associated. Multiple ports are implemented as multiple single-port
+controllers.
+
+* Ethernet controller node
+
+Required controller properties:
+ - #address-cells: shall be 1.
+ - #size-cells: shall be 0.
+ - compatible: shall be "marvell,orion-eth".
+ - reg: address and length of the controller registers.
+
+Optional controller properties:
+ - clocks: phandle reference to the controller clock.
+ - marvell,tx-checksum-limit: max tx packet size for hardware checksum.
+
+* Ethernet port node
+
+Required port properties:
+ - device_type: shall be "network".
+ - compatible: shall be "marvell,orion-eth-port".
+ - reg: port number relative to ethernet controller, shall be 0, 1, or 2.
+ - interrupts: port interrupt.
+ - local-mac-address: 6 bytes MAC address.
+
+Optional port properties:
+ - marvell,tx-queue-size: size of the transmit ring buffer.
+ - marvell,tx-sram-addr: address of transmit descriptor buffer located in SRAM.
+ - marvell,tx-sram-size: size of transmit descriptor buffer located in SRAM.
+ - marvell,rx-queue-size: size of the receive ring buffer.
+ - marvell,rx-sram-addr: address of receive descriptor buffer located in SRAM.
+ - marvell,rx-sram-size: size of receive descriptor buffer located in SRAM.
+
+and
+
+ - phy-handle: phandle reference to ethernet PHY.
+
+or
+
+ - speed: port speed if no PHY connected.
+ - duplex: port mode if no PHY connected.
+
+* Node example:
+
+mdio-bus {
+ ...
+ ethphy: ethernet-phy@8 {
+ device_type = "ethernet-phy";
+ ...
+ };
+};
+
+eth: ethernet-controller@72000 {
+ compatible = "marvell,orion-eth";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x72000 0x2000>;
+ clocks = <&gate_clk 2>;
+ marvell,tx-checksum-limit = <1600>;
+
+ ethernet@0 {
+ device_type = "network";
+ compatible = "marvell,orion-eth-port";
+ reg = <0>;
+ interrupts = <29>;
+ phy-handle = <ðphy>;
+ local-mac-address = [00 00 00 00 00 00];
+ };

This patch adds orion-eth and mvmdio device tree nodes for DT enabled
Dove boards. As there is only one ethernet controller on Dove, a default
phy node is also added with a note to set its reg property on a per-board
basis.

Hi Sebastian
Its probably a good idea to set the local administration bit in this
MAC address. i.e. first byte is 02.

Andrew,
we just need an invalid address here to trigger the default behavior of
the driver and load the MAC address from its register. As PPC binding
documentation also has all zero, I just took it.

The truth is in PPC case, often we set the real mac address with some variables
like 'eth[x]addr' in u-boot prompt, then u-boot will parse that value to fill
the dtb. At last the associated driver can get the actual mac address from the
dtb. And especially for those older u-boot version, even you have to reset the
'local-mac-address' property in dts directly with the real mac address before
generate the dtb since the older u-boot have no this ability to fill dtb again
before pass the kernel.

Tiejun,
with Marvell SoCs it is no different, except that there is almost no dtb
support in their u-boot. The default behavior of the driver always was
to load the MAC address from its register if there is no valid overwrite
value. Using an invalid address (and all zero above is invalid) will
cause of_get_mac_address() to fail (which we allow), the corresponding
platform_data will never be written, and cause the default behavior.
We only need an invalid address passed initially on local-mac-address.
DT aware boot loader will overwrite but DT agnositic boot loader will
not. I can put any invalid MAC address in here, so I have chosen the
very first I can think of.
Sebastian

iirc, our solution to this was to parse the ATAGs for the mac addr and
update the appended dtb. This way, module load and unload would work
without loosing the mac address. I believe Jason Gunthorpe has a patch
to atags_to_fdt() for this... This should allow us to get rid of the
clocks hack.
thx,
Jason.

Sorry, no, we don't use ATAGs here, our platforms start the kernel
with a correct DTB that has the correct mac address to use. My patch
was to have the driver accept it, and I think Sebastian has already
got that functionality...

Not neccessary anyway, after talking Jason C in a Kirkwood-only
workaround I prepared a patch that reads mac address registers early
and stores it in the local-mac-address property.
Just tested on Dockstar with gated clocks and modular DT mv643xx_eth.
Will append to the DT mv643xx_eth patch set if a v5 will be required
or as single patch prior Jason C taking in the ARM part of it
otherwise.

Hmm, maybe a little bit too early. While restoring the MAC address now
works, another bug arises which I guess is related with phy setup
and aneg.
Will investigate and update patch set accordingly.

Cool, chances are, we should be able to take that patch in by itself for

Which patch do you mean? The local-mac-address workaround will only be
available for DT mv643xx_eth because it uses the DT node to store the
MAC.
Anyway, I found the bit that caused the other issue. It is the
Clk125_Bypass_En bit in PORT_SERIAL_CONTROL1 register. What bothers me
about it is:
- Only Dove and Kirkwood have the bit, MV78x00 doesn't have it, Orion5x
doesn't have the register at all. With ppc mv64x60 I can only guess,
but think it is like in Orion5x.
- Reset value of that bit should be 0, but after gating clock on
Kirkwood it is set to 1 causing wrong port clock to be selected.
Also Thomas Petazzoni confirmed that it is set after reset so
either FS is wrong about it or BootROM messes with it.
- Kirkwood and Dove FS tell me that port link must be down when you
change the bit.
As I can't be sure about how mv643xx_eth will behave on other platforms
except Kirkwood and Dove when writing that register, I tend to force
that bit to zero in the driver but only for those two by #ifdefs.

I thought you were replacing the unconditional ethernet clock grabbing
with reading the mac from the registers and updating the dtb? In
mach-kirkwood/board-dt.c?
confused. :-/

True. But there is no node for ethernet controllers in kirkwood.dtsi
yet. It will be there with mv643xx_eth DT patches applied and that is
when the corresponding replacement patch should also be taken in.
I was just confused about your referral to the merge window, because I
guess it is up to David Miller to decide when/whether to take
mv643xx_eth patches in.

Ahh, no, that was me. I was contemplating adding the dt entries in this
merge window at one point and must've got my wires crossed. Sorry for
the confusion.

Ok, have it working now by properly clearing CLK125_BYPASS_EN bit in
PORT_SERIAL_CTRL1 register for Kirkwood only. I have two more patches
ready that I will post as single patches in reply to v4.
If David gives his ACK for the patch set and names a branch to base it
on, I will send a v5 including all patches.

That sounds great, but, FWIW, our bootloaders don't set the MAC
address registers. Does the work around only trigger if the
local-mac-address property is 0?

I already thought about bootloaders not setting the register, but I will
not start parsing 1001 places for a valid MAC only for those. Also
reading the MAC address registers is default behavior of mv643xx_eth if
no MAC address is passed through platform_data.
But you are right, there is plenty of sanity checks in the workaround to
ensure that local-mac-address is only overwritten by it when
- you are on DT
- there is no valid MAC address in that node (of_get_mac_address)
- there is a local-mac-address property with a length of 6 bytes
So this workaround only applies on DT booted kernels with no mac set in
DT.

With all boards converted to DT enabled mv643xx_eth we can now
remove the clock alias for gbe clocks. The workaround for ge0/ge1 clock
gates is not removed, as Kirkwood ethernet controllers loose MAC address
stored in internal registers on gated ge0/ge1 clocks.
Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>
---
Note: I confirm that the above workaround is still required, i.e. when
booting DT kernel with non-DT boot loader (no local-mac-address property)
MAC address registers looses its content on clock gating.

With DT support for mv643xx_eth, board specific init for some boards now
is unneccessary. Remove those board files, Kconfig entries, and
corresponding entries in kirkwood_defconfig.
Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>
---
Note: board-km_kirkwood.c is also removed, as Valentin Longchamp confirmed
the lock-up is not caused by accessing clock gating registers but rather
non-existent device registers. This will be addressed by dtsi separation
for kirkwood and bobcat SoC variants.
Changelog:
v3->v4:
- remove more boards that don't require board specific setup

We still have:
static const char * const kirkwood_dt_board_compat[] = {
"globalscale,dreamplug",
"globalscale,guruplug",
"dlink,dns-320",
"dlink,dns-325",
"iom,iconnect",
"raidsonic,ib-nas62x0",
"qnap,ts219",
"seagate,dockstar",
"seagate,goflexnet",
"buffalo,lsxl",
"iom,ix2-200",
"keymile,km_kirkwood",
"lacie,cloudbox",
"lacie,inetspace_v2",
"lacie,netspace_lite_v2",
"lacie,netspace_max_v2",
"lacie,netspace_mini_v2",
"lacie,netspace_v2",
"mpl,cec4",
"netgear,readynas-duo-v2",
"plathome,openblocks-a6",
"usi,topkick",
"zyxel,nsa310",
NULL
};
in that file. I think it does not make sense that we need to list
boards here that can be described fully by DT. When adding such a
board in the future, you will still need to adapt board-dt.c.
Should we remove the boards that you removed above here as well and
add
"marvell,kirkwood-88f6192",
"marvell,kirkwood-88f6281",
"marvell,kirkwood-88f6282",
"marvell,kirkwood-88f6283",
"marvell,kirkwood-88f6702",
"marvell,kirkwood-98DX4122",
or even just state "marvell,kirkwood"?

True, will remove the redundant compatible strings for v5.
Actually, if I am not missing something, all compatible strings except
"marvell,kirkwood" are redundant as long as board.dts append it
correctly.

I would stick with "marvell,kirkwood" only. This is SoC init code and
we do not distinguish variants here at all.

I just confirmed all kirkwood dts/dtsi properly set "marvell,kirkwood"
in their compatible strings. Will remove all other comapatible strings
from mach-kirkwood/board-dt.c as Simon suggested for v5.

With DT support for mv643xx_eth we do not need legacy platform_data
based setup for DT enabled boards. This patch removes eth setup
for all orion5x DT board files.

Kirkwood ethernet controllers suffer from loosing MAC register content
on gated clocks. In the past this was prevented by not gating the ethernet
controller clocks. With DT support for mv643xx_eth and corresponding
nodes available, a different approach is more reasonable.
This patch replaces the former clock gating workaround by parsing the
ethernet controller nodes for *invalid* MAC addresses and overwrites
the local-mac-address property with MAC register contents early. The
clock can now properly gated in modular mv643xx_eth and DT agnostic
boot loader scenarios because mv643xx_eth will find the stored MAC
in the corresponding MAC address property.

Ethernet controllers found on Kirkwood SoCs not only suffer from loosing
MAC address register contents on clock gating but also some important
registers are reset to values that would break ethernet. This patch
clears the CLK125_BYPASS_EN bit for DT enabled Kirkwood only by using
of_machine_is_compatible() instead of #ifdefs. Non-DT Kirkwood is not
affected as it installs a clock gating workaround because of the MAC
address issue above. Other Orion SoCs do not suffer from register reset,
do not have the bit in question, or do not have the register at all.
Moreover, system controllers on PPC using this driver should also be
protected from clearing that bit.
Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>

Note: In contrast to the reset value of 0 for CLK125_BYPASS_EN bit as
stated in Kirkwood datasheet, we confirmed that reset value is 1 instead.
Either datasheet is wrong about it, there is some post-boot self-check or
BootROM flips that bit.

FWIW, we found that the bootloader has to write to PSC1, the driver
doesn't work with the power on/reset value of the register. So I think
it is safe to assume that all kirkwood bootloaders alter the value.
Our systems write the value 0x00638488 to PSC1.
I looked at patching mv643xx_eth, but ran into the same complexity you
did, it isn't clear what variants of this IP block have the
register/etc.

of_machine_is_compatible seems heavy handed, I would expect this to be
based on the compatible string of the ethernet node itself, not the
machine??

It is safe to assume the bootloader alters it, but that modification is
lost when clocks get gated. I assume on clock ungate, the controller is
reset. Saying this, I will double check Dove's reset value but looks
like reset mess has been fixed in that later SoC.

For Orion SoCs it is quite clear to me, with Gregory Clement and Thomas
Petazzoni we could also confirm if it does any harm there if we
unconditionally clear it. But for PPC system controllers I have no
idea...

I have no strong opinion about checking the machine compatible or have
an extra compatible string for Kirkwood ethernet. Both would work fine
and are checked once upon probe anyway.

Is there a model number variation between IP that needs this and IP that
doesn't? If not, I'm fine with of_machine_is_compatible().

Well the name 'mv643xx' is a family of system controller SOC's
from ages ago, it seems reasonble to continue the trend and label the
IP variations with the SOC name:
compatible = "marvell,kirwood,ethernet", "marvell,mv643xx_eth"

Shouldn't it rather be
compatible = "marvell,kirkwood-eth", "marvell,orion-eth";
I'm inclined to go with of_machine_is_compatible() since the only
concrete difference we know is that the tweak is needed on kirkwood and
nowhere else.
If we had an errata, or a datasheet saying specifically flavor X needs
this and none other does, then we could trigger on the ethernet node
compatible string or a boolean in the node. But we don't have that...
thx,
Jason.

But there is a larger problem here then just this one bit.
The PSC1 register must be set properly for the board layout, and today
we rely on the bootloader to set it. In fact, even with Sebastian's
change the ethernet port won't work without bootloader
intervention. The PortReset bit should also be cleared by the driver
(and it is only present on some variants of this IP block,
apparently).
We know that some Marvell SOC's wack the ethernet registers when they
clock gate, and the flip of Clk125Bypass is another symptom of this
general problem.
So, long term, the PSC1 must be fully set by the driver, based on DT
information describing the board (eg RGMII/MII/1000Base-X [SFP] Phy
type), and the layout of this register seems to vary on a SOC by SOC
basis.
Thus, I think it is appropriate to call this variant of the eth IP
'marvell,kirkwood-eth' which indicates that the register block follows
the kirkwood manual and the PSC1 register specifically has the
kirkwood layout.
The question is what other Marvell SOCs have the same PSC1 layout as
kirkwood?

Ok, so mv643xx_eth would match both "marvell,orion-eth" and
"marvell,kirkwood-eth", then write to PSC1 iff it sees a node matching
"marvell,kirkwood-eth". I'm not too keen on that, however, the matching
of the machine doesn't look to good, either.
Perhaps a better answer is to add a boolean, "marvell,kirkwood_psc1" and
check for that?
Or, marvell,psc1_reset = <0xWWXXYYZZ>;
> The question is what other Marvell SOCs have the same PSC1 layout as

I think marvell,psc1_reset = <>; gives us the most flexibility in
accurately describing the hardware.

Why are you not keen on this? It seems like normal device driver
practice, that is what the data field of of_device_id is typically
used for..
There are more compatible strings than just kirkwood and orion in this
driver, the whole TX_BW_CONTROL_OLD_LAYOUT/TX_BW_CONTROL_NEW_LAYOUT
buisness (affecting PPC/MIPS) should also someday be captured with
compatible strings rather than auto-detection too..

Agree, providing psc1_reset value is a good idea to setup the phy
modes. If all 'orion' SOCs have the PSC1 value then we don't need the
kirkwood differentiators, especially if things like the reset bit are
in the same place.
The same trick Sebastian used to capture the mac address could be used
to capture the PSC1 value from the bootloader.
Basically, I think any IP variants that have idential register layouts
can share a compatible string, otherwise different layouts need
different compatible strings, so the general format:
compatible = "marvell,SOCNAME-eth", "marvell,<something>-eth";
Seems very sane to me. At least this way if we discover more changes
then the driver can match on the SOCNAME compatible string to find
them.
<someting> = orion for TX_BW_CONTROL_NEW_LAYOUT variants also seems
reasonable..
No idea what to call TX_BW_CONTROL_OLD_LAYOUT variants, or the PPC
variants, not important right now it seems.
(BTW, I wonder if the driver should ideally toggle PSC1 reset at some
point????)

I'm not keen on it because we don't have a document saying "All kirkwood
SoCs need PSC1 set to X after reset." We know it, but have we tested
the 6282?
That being said, if "marvell,kirkwood-eth" is the best we can do for
now, I'm all for it. I would just like to be reasonably certain that
the binding we are creating doesn't lock us into a difficult decision
later.

After glancing a LinusW's email, I'm thinking this isn't the correct
path. I'll write more in my response to him.

6282 looses its MAC address, that much i know. I've no idea about
PSC1, but if its MAC address behaviour is the same as 6281, is expect
PSC1 is the same.

Do you have a board set up for testing you could try Sebastian's
forthcoming series on (with "marvell,kirkwood-eth")?

I disagree. The manul is very clear how PSC1 must be set for proper
operation. Clk125BypassEn bit is used only for loopback testing, it
should never set for driver operation. Similarly PortReset must be
cleared for driver operation.
It is always safe for the driver to clear these bits, if it knows they
are available. In fact, I would argue the driver should always clear
these bits so that the bootloader isn't relied on to do it. It doesn't
matter if the SOC errantly sets the bit or not, it can *always* be
safely cleared.
Further, I compared my 88F6282/88F6283 manual against the public
88F6180/88F619x/88F6281 spec and confirmed that the PSC1 layout is the
same.
So all of these SOC's can share a driver compatible string.
AFAICT the only reason the driver doesn't touch PSC1 today is because
the PSC1 was introduced in a later IP revision and its presence isn't
auto-detectable.
The last bit of the puzzle to get bootloader independence on kirkwood
is to encode the phy interface type (GMII/RGMII/BASE-X) in the DT so
the entire PSC1 can be set by the driver..

Even better.

Ok, "marvell,kirkwood-eth" works for me then. I think Sebastian already
has patches for that.

Hmm, let's work on that separately, and later. I've snowballed this
attempt enough ;-)
Thanks for digging into this for us,

Jason, Jason,
sorry I didn't came back to this conversation earlier. I already
reworked the patch to rely on
of_device_is_compatible(.."marvell,kirkwood-eth"..). This is a
kirkwood only thing as other Orions cannot do clock gating or
retain critcal register content (Dove). I will stick with orion-eth
for all other and maybe introduce new compatible strings (and new
fixes) as soon as issues surface.

Actually, fixing modular scenarios is only for the sake of multiarch
someday. I don't see the point in running current kernel without eth
compiled in _on a NAS SoC_ ;)
On Dockstar which I tested, clearing CLK125_BYPASS_EN to make it work
after clock gating, it might be a coincidence that bootloader's PSC1
setup matches reset value here - so please test the patch on other
Kirkwood boards also.
But, as long as no other issue arise, I will not start to modifiy
mv643xx_eth out of the blue. I has been working for ages and breaking
PPC is not my intention. There are other things David Miller already
requested to get fixed and honestly I even thought about a fresh start
for it. Maybe I'll come back to it when barebox gets it's driver
someday.

Which SoCs except Kirkwood? I cannot reproduce any of this behavior on
Dove - and from what I can see from the FS of Orion5x or MV78x00 there
are no clock gating registers.

Agree, but I tend to not go at it now. mv643xx_eth has never set up that
registers and actually it never connects anything else than GMII phy (or
no phy at all). The latter is easy but the for the other, I like to
give up that brain-dead multi-device driver and stick with one device
for both shared and up to three ports. From what I can see from e.g.
ixgbe or any other multi-port eth drivers they all attach the network
device to a single (pci) device.

I didn't choose "marvell,mv643xx-eth" for two reasons
(a) The DT layout is slightly different with phy-handle instead of phy
and marvell prefixed properties. Choosing a compatible string that
matches any PPC compatible string will cause driver racing with sysdev
code to set up platform_data.
(b) I chose to name the controller "orion-eth" and the port
"orion-eth-port" .. PPC has "mv64360-eth" for the port and some
"mv64360-eth-block" or "-group" for the controller. IMHO not intuitive,
but it just a name anyway.

For the _long_ run: Exploit either already present phy properties for
MII and friends or introduce new marvell prefixed .. but not misuse DT
for register values here. Each SoC should setup mv643xx_eth properly,
but that should be based on a clean approach _and_ enough people willing
to test that.
I just have a Dockstar and Topkick which is running 24/7. I didn't even
check if only 6281 suffers from it or also 6282 or maybe only some
revisions of 6281. This patch is a fix, nothing more nothing
less. If you have Kirkwoods around, please test if it suffers from
loosing the MAC address and if it works after insmod with the fix
installed.

IMHO using that is just another workaround for a broken driver. We
could hack the whole register setup in DT as it would still accurately
describe HW. Don't get me wrong, but I don't like it.
Haven't checked how happy Linus Walleij is about pinctrl drivers with
reg values hacked in lately.

One of the things I've been ranting about lately is that Linux
subsystem maintainers have become de-facto device tree
standard commite chairs. :-(
So to the actual question:
In general I think we need to draw a line and define what we
mean with "describing the hardware" in a device tree.
We have some consensus:
- <reg> properties to describe regsiter BASE offset in physical
memory and size.
- Resources like IRQ, DMA channel, regulator, GPIO pin control
handles, are passed using <&ersand> notation.
And so it goes on.
When it comes to defining different registers and their individual
bits and the meaning of these and/or default values, I personally
think that is making things harder for developers rather than
simplifying things. I know that pinctrl-single is anyway doing this
and I was talked into accepting it under circumstances where
developers are being passed opaque machine-generated
data that would otherwise be translated into unreadable header
files littering the kernel.
For a coder it is definately better if the *driver* know these
details, but whether that is possible seems to depend on things
like hardware development process.
IMO: if you want to go down that road, what you really want is not
ever more expressible device trees, but real open firmware,
or ACPI or UEFI that can interpret and run bytecode as some
"bios" for you. With DT coming from OF maybe this is a natural
progression of things, but one has to realize when we reach the
point where what we really want is a bios. Then your time is
likely better spent with Tianocore or something than with the
kernel.
Yours,
Linus Walleij

This is the first I've heard this rant. :(
To that end, I agree with you. My frustration boiled down to trying to
predict the future, which is futile. :-P
For our scenario, once we can confirm our least popular kirkwood
variant, the 6282, behaves the same as we've seen so far, then
"marvell,kirkwood-eth" is fine by me.

shudder. I like embedded systems because the *don't* have a bios.

Then you're into scenarios like I have with my laptop, where - those
of you who check the nightly build results will have noticed - one
of my serial ports doesn't always exist. That's because the ACPI data
in the BIOS is *wrong*. It reports that it has been enabled when it
hasn't, and the disassembled byte code is at fault here.
The fix? God knows. As far as I'm concerned as a user, or even as an
OS developer, it's unfixable without getting the ACPI data structures
changed, and that's not something I can do.
Do you really want that on ARM? Given the fiasco with the location of
the registers, are you sure you want to place more trust in that
direction? Does it give you a warm fuzzy feeling to know that you
might have to work out some way to patch vendor supplied bytecode?

Don't get me wrong. I want mv643xx_eth DT or even platform_data to
evolve to a fully self configured driver not depending on proper u-boot
setup at all.
But I don't want to go that road now and I wonder if it might be safer
for us (and PPC guys) if we start mv643xx_eth over from scratch one day.
For this patch set, I want a basic DT binding that works. Patching the
driver to play with kirkwood loosing the MAC and other important
registers is not my main concern here. If clearing that one bit doesn't
help for all kirkwood boards, I'd rather leave the non-gating
workaround.
mv643xx_eth not knowing DT for ARM is stalling last important bits for
Orion SoCs. I want this to go in first as with David another maintainer
is involved.

Okay, as I mentioned to Jason, I would like to test 6282 before we
settle on this path. Other than that, I'm fine with it.

Good point, but if the eth can be gated to save power, we shouldn't
limit the user's ability just because the SoC is primarily in NAS's.

This cast is completely unnecessary, non-void to void pointer casts
are automatic.
If it is necessary, because p->value is const, then you are trying
to change something behind the OF layer's back and need to use
the appropriate interface to change the property contents.

David,
good you mention it. I added Grant on Cc and will give a short
sum-up why I casted the const from property->value away here.
Maybe I overlooked the API for modifying the DT property but as
far as I've seen - there is no API for modifying it. And yes,
you are right, it is kind of an abuse of DT here.
As Kirkwoods loose their MAC address on clock gating, I was looking
for a place to store it early. (a) DT property "local-mac-address"
looked as a good place as it will allow the driver to find it without
any extra code. Of course, I am doing severaly sanity checks if it is
safe to overwrite it, i.e. no other MAC set, property is there, long
enough.
If Grant also NACKs modifying the DT we basically have two more options
left for Kirkwood: (b) have MAC stored early in two global arrays in
board init and reference that from mv643xx_eth or (c) leave the clock
ungated unconditionally on all Kirkwoods.
I can live with all three, just name it and I prepare a final patch set.
Sebastian

Sparc has an of_set_property(), it needs to become generic.

There is an of_update_property(), we could change the name though, yours
is nicer :-)

Ben, David,
I had a quick look at sparc's of_set_property. Nothing special except it
depends on OF_DYNAMIC at some place. Using of_update_property instead
should be the correct function to use. Thanks for the hint, I'll update
the patches accordingly and send v5 hopefully by today.

The only thing is that of_update_property() is a bit awkward to use,
requiring the caller to provide an allocated struct property with
associated allocated content. It also leaks the old property which
is annoying but we haven't sorted out how to deal with allocation
of properties and property content yet.
It would be handy to be able to just do something like
of_set_property(node, name, ptr, len);
However, that wouldn't help much with the allocation/leak problem,
though at least it would be easier to use. It could also *try* to re-use
the current allocation if the new content is of smaller or equal size.
Cheers,
Ben.

I thought that dtc tried to aggressively save space by folding identical
strings. If you tried to reuse a property that had its contents shared
with another one, you would get interesting results I guess.

It used to be only property names, unless that has changed in recent
dtc. But that's a good point, we probably want a flag in struct property
like we have for nodes, indicating whether it comes from the original
fdt data pool or not.

Ben.

But isn't that what current sparc implementation of of_set_property does
when it marks the property as dynamic?
Anyway, this definitely exceeds my knowledge of OF API for sure, so what
do I do about the MAC workaround now?
Prepare the patch with global arrays and switch to some of_set_property
as soon as it is available?

This is similar to what the "OF_IS_DYNAMIC()" thing on sparc
indicates.

And this is so much better of an interface because it allows the
OF implementation to decide how to deal with memory allocation
and freeing.

of_update_property(). That also makes sure that any notifiers
is called and proc/device-tree is updated in the case where the property
is new.

No, putting it in the DT makes sense, just use the right accessor.

This patch set picks up work by Florian Fainelli bringing full DT
support to mv643xx_eth and Marvell SoCs using it.
The current v5 patch set drops 1:1 compatibiliy with PPC binding
for two reasons:
(a) PPC parses DT nodes in arch/ppc/sysdev and creates non-DT
platform_devices itself,
(b) property and node naming for new ethernet devices is slightly
different ("phy" vs "phy-handle", "marvell," prefix)
Anyway, the two bindings are functionally compatible and PPC bindings
can be converted if desireable. The patch set if fully bisectable and
care has been taken to (a) not reparse on PPC platforms, (b) allow to
use platform_device based registration even if on CONFIG_OF. Not tested
is double registration issues, i.e. if DT nodes are provided but legacy
registration it not yet removed. This double registration should lead
to either non-DT or DT registered device fail on already claimed
ressources.
Also this patch set picks up the opportunity to fix some repeatedly
reported issues with modular mvmdio/mv643xx_eth loading, unloading,
and reloading. It has been tested on SolidRun CuBox (Dove) and
Seagate Dockstar, QNAP, and USI Topkick (Kirkwood) by me or Andrew
Lunn.
Patch 1 fixes an issue introduced with switch to separate mvmdio
driver, where detaching mv643xx_eth from a phy will not stop the
phy state machine and finally dereference the already removed network
device. Using phy_disconnect properly stops the phy state machine
before detaching from it. Perhaps, this patch should go back in
stable (most likely 3.9 only) if mvmdio separation patch went in
there.
Patch 2 makes use of managed devm_ioremap for the last remaining
non-managed resource.
Patches 3-4 prepare DT support for mv643xx_eth by adding a phy_node
pointer to platform_data and exploiting that phy_node when attaching
to a phy.
Patch 5 adds a Kirkwood specific workaround for PORT_SERIAL_CTRL1
register which is reset to loopback mode when clocks are gated.
Patch 6 introduces DT parsing support for mv643xx_eth by adding a
match table for marvell,orion-eth and marvell,kirkwood-eth to the
shared driver and adding a platform_device for each of its child
nodes.
Patches 7-9 add corresponding device tree nodes to Marvell Dove,
Kirkwood, and Orion5x including all boards. Where known, also
the PHY compatible string has been set to what is reported in the
boards boot loader.
Patches 10, 11-12, and 14 finally remove all legacy platform_device
based registration from Dove, Kirkwood, and Orion5x DT setup. For
Kirkwood also now obsolete board specific setup is removed from
common DT board setup, Kconfig, Makefile, and kirkwood_defconfig.
For the patches above I suggest to take Patches 1-6 through David
Miller's branch, and Patches 7-12 through Jason Cooper's when the
former have appeared on mainline linux. The patch set has been based
on v3.10-rc3.
Overall Changelog:
v4->v5: v5 drops Kirkwood MAC address workaround by using DT
property because OF API does not allow to modify properties
easily. Instead the current workaround by not gating ge clocks
is kept. The OF property workaround is postponed until some
easy to use of_set_property is available.

Using a separated mdio bus driver with mvmdio, phy_detach on network device
removal will not stop the phy and finally lead to NULL pointer dereference
in mvmdio due to non-existent network device. Use phy_disconnect instead
to properly stop phy device from accessing network device prior removal of
the network device.

Note: I observed this behavior when removing a modular mv643xx_eth driver
after attaching it to a phy handled by (also modular) mvmdio. The mvmdio
conversion has been done in
commit c3a07134e6aa5b93a37f72ffa3d11fadf72bf757
("mv643xx_eth: convert to use the Marvell Orion MDIO driver")

This connects to a phy node passed to the port device instead of probing
the phy by phy_addr.

Ethernet controllers found on Kirkwood SoCs not only suffer from loosing
MAC address register contents on clock gating but also some important
registers are reset to values that would break ethernet. This patch
clears the CLK125_BYPASS_EN bit for DT enabled Kirkwood only by using
of_device_is_compatible() instead of #ifdefs. Non-DT Kirkwood is not
affected as it installs a clock gating workaround because of the MAC
address issue above. Other Orion SoCs do not suffer from register reset,
do not have the bit in question, or do not have the register at all.
Moreover, system controllers on PPC using this driver should also be
protected from clearing that bit.
Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>
---
Note: In contrast to the reset value of 0 for CLK125_BYPASS_EN bit as
stated in Kirkwood datasheet, we confirmed that reset value is 1 instead.
Either datasheet is wrong about it, there is some post-boot self-check or
BootROM flips that bit.
Changelog
v4->v5:
- check for device compatible instead of machine compatible

This adds device tree parsing support for the shared driver of mv643xx_eth.
As the bindings are slightly different from current PPC bindings new binding
documentation is also added. Following PPC-style device setup, the shared
driver now also adds port platform_devices and sets up port platform_data.
Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>
---
Note: Although different, device tree bindings are compatible with PPC
bindings. As I do not have access to any PPC platform using mv643xx_eth,
I leave conversion ("phy" vs "phy-handle") and compatible string name
up to PPC guys.
Due to hang reports for modular built mvmdio and mv643xx_eth, I have
tested module loading/unloading/reloading on CuBox (Dove) and Dockstar
(Kirkwood) without any issues for the whole patch set.
Changelog:
v5->v4:
- add Kirkwood specific compatible string
v3->v4:
- separation of independent patches (phy, of_mdio, devm)
- stand-alone device tree binding compatible to existing mv64x60 binding
- device node match for shared driver only
- device node registration for port drivers
- properly return -EPROBE_DEFER on missing of phy (Reported by Simon Baatz)

+Marvell Orion/Discovery ethernet controller
+=============================================
+
+The Marvell Discovery ethernet controller can be found on Marvell Orion SoCs
+(Kirkwood, Dove, Orion5x, and Discovery Innovation) and as part of Marvell
+Discovery system controller chips (mv64[345]60).
+
+The Discovery ethernet controller is described with two levels of nodes. The
+first level describes the ethernet controller itself and the second level
+describes up to 3 ethernet port nodes within that controller. The reason for
+the multiple levels is that the port registers are interleaved within a single
+set of controller registers. Each port node describes port-specific properties.
+
+Note: The above separation is only true for Discovery system controllers.
+For Orion SoCs we stick to the separation, although there each controller has
+only one port associated. Multiple ports are implemented as multiple single-port
+controllers. As Kirkwood has some issues with proper initialization after reset,
+an extra compatible string is added for it.
+
+* Ethernet controller node
+
+Required controller properties:
+ - #address-cells: shall be 1.
+ - #size-cells: shall be 0.
+ - compatible: shall be one of "marvell,orion-eth", "marvell,kirkwood-eth".
+ - reg: address and length of the controller registers.
+
+Optional controller properties:
+ - clocks: phandle reference to the controller clock.
+ - marvell,tx-checksum-limit: max tx packet size for hardware checksum.
+
+* Ethernet port node
+
+Required port properties:
+ - device_type: shall be "network".
+ - compatible: shall be one of "marvell,orion-eth-port",
+ "marvell,kirkwood-eth-port".
+ - reg: port number relative to ethernet controller, shall be 0, 1, or 2.
+ - interrupts: port interrupt.
+ - local-mac-address: 6 bytes MAC address.
+
+Optional port properties:
+ - marvell,tx-queue-size: size of the transmit ring buffer.
+ - marvell,tx-sram-addr: address of transmit descriptor buffer located in SRAM.
+ - marvell,tx-sram-size: size of transmit descriptor buffer located in SRAM.
+ - marvell,rx-queue-size: size of the receive ring buffer.
+ - marvell,rx-sram-addr: address of receive descriptor buffer located in SRAM.
+ - marvell,rx-sram-size: size of receive descriptor buffer located in SRAM.
+
+and
+
+ - phy-handle: phandle reference to ethernet PHY.
+
+or
+
+ - speed: port speed if no PHY connected.
+ - duplex: port mode if no PHY connected.
+
+* Node example:
+
+mdio-bus {
+ ...
+ ethphy: ethernet-phy@8 {
+ device_type = "ethernet-phy";
+ ...
+ };
+};
+
+eth: ethernet-controller@72000 {
+ compatible = "marvell,orion-eth";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x72000 0x2000>;
+ clocks = <&gate_clk 2>;
+ marvell,tx-checksum-limit = <1600>;
+
+ ethernet@0 {
+ device_type = "network";
+ compatible = "marvell,orion-eth-port";
+ reg = <0>;
+ interrupts = <29>;
+ phy-handle = <ðphy>;
+ local-mac-address = [00 00 00 00 00 00];
+ };
+};

This patch adds orion-eth and mvmdio device tree nodes for DT enabled
Dove boards. As there is only one ethernet controller on Dove, a default
phy node is also added with a note to set its reg property on a per-board
basis.

With DT support for mv643xx_eth board specific init for some boards now
is unneccessary. Remove those board files, Kconfig entries, and
corresponding entries in kirkwood_defconfig.
Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>
---
Note: board-km_kirkwood.c is also removed, as Valentin Longchamp confirmed
the lock-up is not caused by accessing clock gating registers but rather
non-existent device registers. This will be addressed by dtsi separation
for kirkwood and bobcat SoC variants.
Changelog:
v3->v4:
- remove more boards that don't require board specific setup

Just a stupid note: With Thomas ongoing work to get mvebu-pcie driver in
place and enabled for kirkwood, some boards setup files will also lose
their pcie init routines, which may allow you to kill those additonal
files soon.
For instance 6bd98481ab34 (arm: kirkwood: NETGEAR ReadyNAS Duo v2 init
PCIe via DT) currently sitting in jcooper/mvebu/pcie_kirkwood removes
the PCIE init routine in board-readynas.c, and yours remove ge00
init. With both applied, the whole file can go away.
AFAICT, this may be the case soon for:
arch/arm/mach-kirkwood/board-iconnect.c (36e5722089)
arch/arm/mach-kirkwood/board-mplcec4.c (9470fbfb8d)
arch/arm/mach-kirkwood/board-nsa310.c (40fa8e5da2)
arch/arm/mach-kirkwood/board-readynas.c (6bd98481ab)
arch/arm/mach-kirkwood/board-ts219.c (259e234608)
Anyway, thanks for this work Sebastian.
Cheers,
a+

Arnaud,
I already realized this when merging Jason's recent PRs and put
mv643xx_eth patches on top. I am aware of it but as ARM part of
mv643xx_eth will be delayed until net part surfaces, we have
plenty of time to react on current updates to mach-kirkwood
boards.
Sebastian

Yes, we're very excited about this ;-)

Would you mind putting a patch together (for after v3.10 drops) to do
this? If you applied Sebastian's series on top of mvebu/pcie_kirkwood,
that should get you almost there. The last half of his series is going
in after v3.10...
You may want to try merging in mvebu/boards and mvebu/soc. Those have
the changes to use dt for the restart and power-off drivers. That'll
allow us to empty out a few more board files. mvebu/dt also has a patch
from Valentin allowing us to remove the keymile board as well.
thx,
Jason.

Something like the quick quilt-generated patch at the end of this email
(done after a dummy merge of Sebastian's set in mvebu/pcie_kirkwood)? I
will take a look at what remains after Sebastian's set hit one of your
branch but I guess he will have included most of what is in the patch to
help you with the merge.
Anyway, at the end here is what DT board files would remain:
$ ls -1 arch/arm/mach-kirkwood/board-*.c
arch/arm/mach-kirkwood/board-dnskw.c
arch/arm/mach-kirkwood/board-dt.c
arch/arm/mach-kirkwood/board-lsxl.c
arch/arm/mach-kirkwood/board-ts219.c
Just one question though: the removal of MACH_*_DT in Kconfig removes
the automatic selection of useful board specific options like
ARM_APPENDED_DTB, ARM_ATAG_DTB_COMPAT, POWER_RESET_RESTART,
POWER_RESET_QNAP. Is that expected?

yes. After a merge w/ mvebu/boards to get restart and poweroff would
allow to get rid of board-ts219.c and board-lsxl.c, leaving mainly
board-dnskw.c.

This one seems to just be setting a gpio to enable reboot after power
failure. Should be simple to move to DT.

We obviously need this one. ;-)

This is taken care of in mvebu/boards

Also in mvebu/boards

I would select POWER_RESET_QNAP and POWER_RESET_RESTART in Kconfig for
ARCH_KIRKWOOD_DT, and put ARM_APPENDED_DTB and ARM_ATAG_DTB_COMPAT into
the defconfig.

With DT support for mv643xx_eth we do not need legacy platform_data
based setup for DT enabled boards. This patch removes eth setup
for all orion5x DT board files.

David,
thanks for pulling these in. I finally found how to check if a patch

#1 fixes did not yet went into -stable. Can you unqueue it? Sorry for
the confusion.
Sebastian
