[PATCH 0/9] ARM: Kirkwood: Convert to pinctrl

[PATCH 0/9] ARM: Kirkwood: Convert to pinctrl

[Andrew Lunn]

This patchset converts all DT kirkwood boards to using pinctrl.

This patchset depends on an earlier patchset to allow the mvebu
pinctrl driver and gpio driver to be built for kirkwood.

Only the TS219 conversion has been tested on hardware. The remaining
are compile tested. Before merging upstream, it would be good if the
others could be tested on hardware.

This series along with the dependents can be found in:

git://github.com/lunn/linux.git v3.7-rc2-pinctrl

[PATCH 1/9] ARM: Kirkwood: Convert TS219 to pinctrl.

[Andrew Lunn]

Make use of the pinctrl driver for configuring all the pins, instead
of using the Orion mpp code.

[PATCH 0/9] ARM: Kirkwood: Convert to pinctrl

[Josh Coombs]

Andrew, are there any required kernel config changes to go along with
this?  I didn't see any updates to the default configs in the patches
so I want to make sure I'm testing with the right options enabled.

Hi Josh

I've been testing with is:

make kirkwood_defconfig
make 

The _defconfig file now contains all boards and should build most
common drivers to get the boards booted. If something critical is
missing for your boards, please let us known and we will add it to
_defconfig.

Unfortunately, this doesn't work for me. git bisect tells me its commit 
e01139ec82162f21875d09e820686aede4219695.

I guess it has something to do with the lsxl_init calling gpio_set_value().

Are you sure you don't need to add a

	select PINCTRL

in the CONFIG_ARCH_KIRKWOOD symbol?

It would be really better to have those under each device, rather than
globally declared here. For some devices such as UARTs, it is not yet
possible with the 8250 driver to associate pinctrl pins (but I'm
planning to work on that soon). However for the other drivers (SPI,
TWSI, SATA, button), it should be possible.

All those definitions are not board specific, they are common to the
SoC. So they should be in the corresponding .dtsi file.

Basically:

 * The SoC .dtsi file should define all the pinmux groups that are
   described in the datasheet and are used by boards. I.e, there may be
   conflicting groups defined, where one group configures pin X with
   function Y, while another group configures pin X with function Z.

 * The board .dts file should define the pinmux groups that are really
   board-specific (buttons, LEDs, etc.), and then for each device,
   point to the correct pinmux group (either defined in the .dtsi file
   or in the board file).

See for example imx28.dtsi, and then the boards such as
imx28-cfa10036.dts, imx28-evk.dts, imx28-m28evk.dts, imx28-tx28.dts.

Best regards,

Thomas

Thomas,

Agree, but for now a global pinhog on pinctrl node itself is the correct
way to go here. As soon as there is pinctrl support in the specific
device drivers we can move pinmux phandle there.

Here I disagree. Even quite simple interfaces like uart can have dozens
of possible mpp configurations, e.g. rx/tx on up to three different pins
each plus rts/cts on various pins plus all possible combinations.

Now consider some more complex interface with more than one mpp pin per
interface pin. Do you really want to predefine all possible combinations
even if it is more likely that in fact only one is used on all boards
because they are all based on the same reference design?

With respect to mpp the actual configuration _is_ board specific. There
are maybe only some pins that are always used if a specific interface is
used, e.g. nand pins on dove can only be switched with gpio.

Where did I say that you should define *all* possible configurations?

I said: "The SoC .dtsi file should define all the pinmux groups that are
described in the datasheet and are used by boards". Read again the "and
are used by boards".

So I'm clearly not advocating adding *all* possible configurations,
because there would be gazillions of them. But I'm in favor of moving
the *used* configurations to the .dtsi files.

I am not sure to follow you here. There is clearly some MPP pins whose
muxing groups can be defined in the SoC level file, and some other MPP
pins whose muxing should entirely be done at the board level file.

For a UART, the .dtsi file can define a pinmux configuration for
RX/TX/RTS/CTS, and the .dts file only needs to reference this
configuration.

For LEDs, buttons and similar things, the pinmux configuration should
be defined in the .dts file, and of course the .dts file will reference
this configuration.

I think what Shawn Guo did with i.MX 28 is really neat. In the current
patches posted by Andrew, for example, the following piece:

+			pmx_uart1: pmx-uart1 {
+				marvell,pins = "mpp13", "mpp14";
+				marvell,function = "uart1";
+			};

is needlessly repeated in kirkwood-ts219-6281.dts,
kirkwood-ts219-6282.dts and kirkwood-dnskw.dtsi. This is clearly a
pinmux configuration that sets up TXD/RXD of UART1, and it should be in
kirkwood.dtsi.

Best regards,

Humm.

I guess it is too early to use gpio. I don't think the gpio driver has
not been configured yet.

I need to think about this.

What happens if you comment out these two gpio_set_value calls?

This definition (compatible + reg) should go in kirkwood.dtsi. The
pinctrl unit should be declared at the SoC level. Ditto for all other
patches.

This is not a strong comment, but I am not sure it is really useful to
define one pinmux configuration for each pin. You can do something like:

	pmx_buttons: pmx-buttons {
		marvell,pins = "mpp45", "mpp46", "mpp47", "mpp48";
		marvell,function = "gpio";
	};

I think all the pins used for buttons or for LEDs kind of make sense to
be muxed together. And then, when you declare the LEDs in the DT, you
can do:

                leds {
                        compatible = "gpio-leds";
                        pinctrl-names = "default";
                        pinctrl-0 = <&led_pins>;

                        red_led {
                                   label = "red_led";
                                   gpios = <&gpio1 17 1>;
                                   default-state = "off";
                        };

                        yellow_led {
                                   label = "yellow_led";
                                   gpios = <&gpio1 19 1>;
                                   default-state = "off";
                        };

                        green_led {
                                   label = "green_led";
                                   gpios = <&gpio1 21 1>;
                                   default-state = "off";
                                   linux,default-trigger = "heartbeat";
                        };
                };

Where "led_pins" is a pinmux configuration that includes three pins.

I can probably help figuring out what the problem is. Do you have a
patch that exhibits the problem so I can test it here?

The reg maybe. Compatibility not. We need to tell pinctrl which of the
5 different variants of kirkwood this particular kirkwood is. See

drivers/pinctrl/pinctrl-kirkwood.c

enum kirkwood_variant {
        VARIANT_MV88F6180 = V(1, 0, 0, 0, 0),
        VARIANT_MV88F6190 = V(0, 1, 0, 0, 0),
        VARIANT_MV88F6192 = V(0, 0, 1, 0, 0),
        VARIANT_MV88F6281 = V(0, 0, 0, 1, 0),
        VARIANT_MV88F6282 = V(0, 0, 0, 0, 1),
};

static struct of_device_id kirkwood_pinctrl_of_match[] __devinitdata = {
        { .compatible = "marvell,88f6180-pinctrl", .data = &mv88f6180_info },
        { .compatible = "marvell,88f6190-pinctrl", .data = &mv88f6190_info },

        { .compatible = "marvell,88f6282-pinctrl", .data = &mv88f6282_info },

The way we solved that on Armada XP is that we have a common
armada-xp.dtsi file with definitions common to all SoCs in the family.
Then, we have sub .dtsi files named armada-xp-mv78230.dtsi,
armada-xp-mv78260.dtsi and armada-xp-mv78460.dtsi that handle the
differences between specific SoCs in the family. For example, the
differences are: different compatible string for the pinctrl driver,
different number of CPUs, different number of pins and
therefore different number of GPIOs, different number of PCIe ports,
etc. But besides those differences, most units have a lot of common
definitions, that we factor out in armada-xp.dtsi.

So we have the following hierarchy:

 + armada-xp.dtsi
   + armada-xp-mv78230.dtsi
     + someboard-here.dts
   + armada-xp-mv78260.dtsi
     + openblocks-ax3-4.dts
   + armada-xp-mv78460.dtsi
     + armada-xp-db.dts

After commenting out and fixing the mpp funtions (see earlier mail from me) 
the kernel hangs after rtc-mv/before orion_wdt.

The problem is (probably, I haven't tested) that in
mach-kirkwood/board-dt.c, the of_platform_populate() function is called
after all the board-specific init. So all the devices described in the
DT, including GPIO banks, have not been registered yet. Most likely the
of_platform_populate() should come before the board specific inits.

Also there should probably  be a gpio_request() before those
gpio_set_value().

Best regards,

Thomas

Thanks Thomas, i will play around with this.

I'm just wondering if we are going to get into ordering issues. These
gpio operations are providing power to subsystems. We probably need
that to happen before the driver is loaded. If we call
of_platform_populate() too early, do we have the danger the driver
probing is going to happen before the init routine can enable the
power?

It seems like we want pinctrl/gpio working first, with pins hogged as
specified in DT, then the board init() function, then the rest of DT
setup.

> Also there should probably  be a gpio_request() before those
> gpio_set_value().

Yes. That worked before, but might break now. Most of the init()
functions do actually make a gpip_request() call.

If those GPIO value settings are needed to get a particular driver to
work, then I'd recommend letting the driver do the GPIO value setting.
For example, in the lsxl board, I see:

        /* usb and sata power on */
        gpio_set_value(LSXL_GPIO_USB_POWER, 1);
        gpio_set_value(LSXL_GPIO_HDD_POWER, 1);

If the LSXL_GPIO_USB_POWER GPIO should be set to one to get the EHCI
driver to work properly, then I think we should let the EHCI driver set
this GPIO value in its ->probe() operation. Of course, the GPIO
reference will be passed in the platform_data (for old-style probing),
or through specific DT properties (for new-style, DT-based, probing).

Regarding the LSXL_GPIO_HDD_POWER GPIO, I am not sure. Is it required
to apply power on this GPIO to get the SATA driver to probe properly,
or is it possible to get the SATA driver to probe properly, then apply
power and have the HDD still being recognized? I haven't looked at all
at how SATA drivers were working, so I can't say.

Also, ultimately, if those GPIOs are providing power, then they should
probably not be handled as simple GPIOs, but rather as regulator, using
the gpio-regulator driver. But let's do things steps by steps :-)

Best regards,

LSXL_GPIO_USB_POWER and LSXL_GPIO_HDD_POWER switches the power on the USB
and SATA connector. So they are not needed to be set before the driver
probes, at least in my case here.

But i can imagine boards where you have to enable some kind of
buffer/muxer/etc which are controlled by GPIO pins. And I don't think that
should be part of the actual driver, because that would be highly board
dependant.

Ok.

You'd have to provide a more specific example so I can imagine how it
will be solved. But for example, if you have a GPIO-controlled muxer
for an I2C bus, then the I2C devices behind the muxer are described as
sub-devices of the muxer, so the probing order is correct.

Of course, I'm not pretending I have ready-to-use solutions for all
situations, but I think we can solve this problem on a case-by-case
basis.

Regardless of those GPIOs, did you solve the hang that happened even
when you removed the gpio_set_value() calls? Or is it still a problem
currently?

Best regards,

Thomas

Assume an ethernet phy which needs a valid reference clock before it can be 
probed for example. Of course, this is pure theoretical. But should we impose 
restrictions on when we can do the GPIO settings? Esp. since it worked before 
(i guess).

Still a problem. Haven't really looket into i atm. Hopefully i find some time 
this weekend.

FWIW, Applying power to the HDD after SATA probe works fine on my NAS 
(admittedly not an lsxl board, but close enough). Turning it off again is 
a little unclean, but works.

[PATCH 3/9] ARM: Kirkwood: Convert dnskw to pinctrl

[Jamie Lentin]

Thanks for doing all this. Some typos to fix, I've commented below but 
I thought it might be easier to push a version for you to steal. It's 
here:

git://github.com/lentinj/linux.git v3.7-rc2-pinctrl
https://raw.github.com/lentinj/linux/v3.7-rc2-pinctrl/arch/arm/boot/dts/kirkwood-dnskw.dtsi

Tested on a DNS-320, not a DNS-325 yet.

Similar to lsxl_init, the custom GPIO registrations fail:-

dnskw: failed to configure power-off GPIO
dnskw: Failed to register dnskw:power:sata0
dnskw: Failed to register dnskw:power:sata1
dnskw: Failed to register dnskw:power:recover

So I guess they will need a new home somewhere.

However most things (fan, buttons, SATA detect/power via sysfs, power via 
sysfs) work. The key thing that doesn't is LEDs. Registration looks 
reasonable:

Registered led device: dns320:blue:power
kirkwood-pinctrl f1010000.pinctrl: request pin 43 (PIN43) for mvebu-gpio:43
Registered led device: dns320:blue:usb
kirkwood-pinctrl f1010000.pinctrl: request pin 28 (PIN28) for mvebu-gpio:28
Registered led device: dns320:orange:l_hdd
kirkwood-pinctrl f1010000.pinctrl: request pin 27 (PIN27) for mvebu-gpio:27
Registered led device: dns320:orange:r_hdd
kirkwood-pinctrl f1010000.pinctrl: request pin 35 (PIN35) for mvebu-gpio:35
Registered led device: dns320:orange:usb

However setting brightness on/off does the following:
cat /sys/class/leds/dns320\:blue\:power/trigger

dns320:blue:power - No effect, LED continues to blink as bootloader 
configures it
dns320:orange:l_hdd - Works fine
dns320:orange:r_hdd - Works fine
dns320:orange:usb - Turns on, turning off locks NAS hard
dns320:blue:usb - Turns on, turning off locks NAS hard

Any ideas?

Cheers,

Need a &pmx_sata0 too (see below).

Shouldn't be repeated, I'm guessing.

mpp4 is for the NAND. I'm guessing mpp22 should be mpp21, but this should 
have the "sata0" function.

On a related note, the NAND pins aren't registered. I probably should have 
done this before, although if the bootloader didn't set up the NAND pins 
then it'd probably not get this far :)

These don't actually do anything (there's no more NAS functions left to 
find now), so could they just be left out? They didn't serve any purpose
before other than making it easy to see where the gaps were.

Should be "gpo", but could just leave out all 4.

This one wasn't registered above, but not a used pin.

Thanks. I will probably squash the three patches into my original, and
add a Signed-off-by: if that is O.K. for you.

I hope to look at this problem this weekend. Maybe a gpio regulator
could be a solution, or loading the pinctrl stuff earlier. We will
see.

First thing that comes to mind, is it registering them for the correct
GPIO controller. I think with the new setup, pinctrl and gpio are
closely linked, so maybe, its modifying pins on the wrong controller.
Bit of a long shot....

I just turned the existing MPP setup into pinctrl. Things like SATA,
SPI pins, etc, i left alone if they were not configured in the old C
code. I've no problems adding them here.

        MPP_MODE(4,
                MPP_VAR_FUNCTION(0x0, "gpio", NULL,      V(1, 1, 1, 1, 1)),
                MPP_VAR_FUNCTION(0x1, "nand", "io6",     V(1, 1, 1, 1, 1)),
                MPP_VAR_FUNCTION(0x2, "uart0", "rxd",    V(1, 1, 1, 1, 1)),
                MPP_VAR_FUNCTION(0x5, "sata1", "act",    V(0, 0, 1, 1, 1)),
                MPP_VAR_FUNCTION(0xb, "lcd", "hsync",    V(0, 0, 0, 0, 1)),
                MPP_VAR_FUNCTION(0xd, "ptp", "clk",      V(1, 1, 1, 1, 0))),

4 can be both NAND and SATA. It looks like NAND has to use pins
mpp0-mpp5,mpp18-mmp19, they are not available anywhere else. SATA1 is
duplicated, so we have to be careful to get the right pins.

Maybe boot the old kernel and look these lines:

[   16.187814] initial MPP regs: 01112222 43303311 55550000 00000000 00000000 00000000 00000000
[   16.187833]   final MPP regs: 01552222 03303311 55550000 00000000 00000000 00000000 00000000

The first line is how uboot setup the MPP pins. The second is after
the init function was called.

I did look at using the gpio-regulator stuff a while back, and decided it 
wasn't quite the right shape. Although I can't remember why, and it might 
have changed since.

The power-off GPIO registration could happen in dnskw_power_off instead, 
or the attempt at a gpio-poweroff driver could be resurrected (I'd 
forgotten about it until now).

I could accept dnskw:power:recover is a weirdo configuration option that 
should be set in the bootloader / userland rather than the kernel 
supporting it. Although it would be nice if the kernel registered it's 
purpose. Maybe GPIO pins could be exported by adding sub-nodes to the GPIO 
chip, if that's not too hackish?

I did wonder that, but then why would turning the LEDs on work fine? I 
wonder if both pins are being toggled or something. I'll investigate 
further and report back. The two that cause the NAS to lock up are the 
only ones on &gpio1 though.

The sata0 and sata1 activity leds are definitely MPP20 and MPP21---I've 
set them up as GPIO leds before successfully.

initial MPP regs: 01111111 03303311 00551100 00000000 00000000 00000000 00000000

Although the initial MPP regs is also set by a recompiled u-boot with 
~identical MPP setup code.

I dusted the code off last weekend, but ran out of time.  I wanted to
make it also support the pxa use-case.

We need some sort of solution. It is quite common to use GPIO this
way, to enable power, etc. So either we need some form of gpio
regulator, or the ability to set gpio defaults as you said in the gpio
DT node, or fix the ordering so the init function can set them up.

What would they map to on gpio0? NAND?

It might be useful to generate the same sort of dumps with the new
driver, even if its code just hacked in for testing.

Okay, I'm unlikely to get a chance to have a play with it for a week or so 
but if I do I'll let you know.

Setting the defaults in the DT gpio node would get my vote, as it pretty 
much removes board-dnskw.c, and there'd be easy sysfs files to turn the 
pins on/off (maybe someone out there doesn't want their NAS to turn back 
on after a power failure...).

3 & 11, so NAND and UART0 RX. But it's not just that the console is dead, 
I can't ping the NAS any more either. However the power LED is still 
blinking via. hardware GPIO blink.

I'd been looking at the debugfs output if you hadn't spotted it:

root at rocoto:~# cat /debug/pinctrl/f1010000.pinctrl/pinmux-pins
Pinmux settings per pin
Format: pin (name): mux_owner gpio_owner hog?
pin 0 (PIN0): f1010000.pinctrl (GPIO UNCLAIMED) (HOG) function nand group mpp0
pin 1 (PIN1): f1010000.pinctrl (GPIO UNCLAIMED) (HOG) function nand group mpp1
pin 2 (PIN2): f1010000.pinctrl (GPIO UNCLAIMED) (HOG) function nand group mpp2
  . . .

Although it doesn't say what the initial MPP setup was.

[PATCH 6/9] ARM: Kirkwood: Convert GoFlex Net to pinctrl.

Initial test with my 3.7-rc2 DT kernel config failed when it tried to
build modules:

I didn't realize my play kernel test package still includes the
following patch, I thought it had been dealt with already.  Should I
start a new thread on this issue?

In the mean time, I'll start a build with the default conf as

quick update, i found out, that my board loops in the mvebu interrupt handler 
mvebu_gpio_irq_handler(). maybe this is also the lockup Jamie Lentin sees.

are interrupts always enabled, now? is there a way to control them? maybe 
there is something missing in the dts, now.

Ah, this is interesting. It is not entirely surprising, since the gpio
driver is new. Even though it re-uses most of the previous gpio driver,
it is by far not impossible that there will be a few regressions.

Could you add a few debug prints to see if you're looping *inside* the
function (which I find pretty unlikely), or if the function gets called
over and over again? Could it be that the hang occurs during the
initialization of the gpio-leds or gpio-keys drivers?

Also, even though I'm pretty sure it isn't going to fix your problem,
note the following mvebu-gpio fix:

  http://article.gmane.org/gmane.linux.ports.arm.kernel/195018

Best regards,

ah sorry, my bad. of course the handler is called forever:

yeah, if i disable gpio-leds, gpio-keys and gpio-fan the hang will disappear. 
But once i enable one of it the board hangs again.

Hi Josh

It is a known issue which i've seen discussed on the lists. I expect
it to be fixed soon.

That makes me think edge vs level triggering.

For gpio-keys you want edge triggered interrupts, but if the
controller is setup for level, you would see this.

Try adding some debug into the function mvebu_gpio_irq_set_type()

[PATCH 0/9] ARM: Kirkwood: Convert to pinctrl

[Andrew Lunn]

Thanks for the feedback everybody gave.

Progress has been made:

The bug causing the lockups has been found, fixed and passed upstream.

I factored out the repeated pinmux definitions for sata0, sata1, spi,
twsi0, uart0, uart1.

I fixed a few types reported by testers.

I found a solution to many of the gpio_request() failures. The ones
for controlling power to SATA or USB i've replaced with a regulator in
DT. The regulator will grab the GPIO, set it to output, and driver it
high/low as required. I just hope we don't have an ordering issue.
The regulator framework seems to load quite early and probes all the
regulators. This fails, because pinctrl has not yet loaded, so the
gpio framework returns EPROBE_DEFER. This is not fatal to the
regulator framework, it tries again later. But this later is after
most of the rest of the drivers have loaded. So we might get into
issues where uboot has not enabled power to USB/SATA, the driver is
probed and fails because of the lack of power, and once things of gone
wrong, we turn the power on.

I still expect problems with GPIOs used for power off. I've not yet
touched them. Again, a regulator makes sense, but there is no 'out of
the box' regulator type or property which adds itself to pm_power_off.

The last problem is:

        /* Set NAS to turn back on after a power failure */
        dnskw_gpio_register(37, "dnskw:power:recover", 1);

I think its a bit of a stretch calling this a regulator.

Since the current patchset is 18 patches, plus a few other bug fixes
and dependencies, i'm not going to post them all here. I think we are
still at the smoke/no-smoke stage of testing. Please pull from:

git://github.com/lunn/linux.git v3.7-rc2-pinctrl-v2

and let me know if things work, what typo's need fixing, where the
smoke comes out, etc.

      Thanks
	Andrew

the IB-NAS 62x0 works with the exception of the power off via GPIO. 
Additionally, the original U-Boot enables hardware blinking for the
power led and Jamie's patch might be needed here as well.  However, I
don't use this U-Boot anymore and can't test this.

Hi Simon

Thanks for testing.

I hope Thomas Petazzoni will pickup the blinking patch and make sure
its O.K. for 370/XP. It can then be merged in.

power off via GPIO is next on my list of things to solve.

No smoke came out, the SATA ports were both powered up. Beyond what's 
already known about, no problems.

[RFC PATCH 0/2] Kirkwood 98dx4122 pinctrl variant

[Valentin Longchamp]

These two patches add a pinctrl variant for the kirkwood embedded in the
98dx4122 SoC. Although it is based on a 6281 kirkwood, a lot of pins and
functionalities are absent ant that's why a new variant is needed.

These two patches are based on Andrew's v2 pinctrl branch:

[PATCH 1/2] ARM: support 98DX412x kirkwoods with pinctrl

[Valentin Longchamp]

The Marvell 98DX412x SoC embed a kirkwood variant that does not have
pinctrl support yet. Even though this kirkwood is very similar to the
88f6281, on the MPP front a lot of pins are not available. That's why a
new kirkwood pinctrl variant is needed.
