[PATCH v2 00/18] arm64: dts: allwinner: A64 boards DT updates

[Andre Przywara]

Hi,

compared to v1, this adds Samuel's Orange Pi Win series in a split-up
form, fixes some issues with the Olinuxino and addresses the other
comments on the list.
The first 12 patches should be fine. I would be grateful for Tested-by's
on the other six patches.

-----------------------------------------
While starring at some DTs while copying the kernel DTs into the U-Boot
tree, I realised that some boards seem to get more love than others.
Fix up some issues I found by inspection on some boards:
Patch 1 adds L2 cache nodes, to avoid a message on the boot console.
Patch 2 adds a separate DT file for the Pine64-LTS board, which from the
software point of view is very much a SOPine + baseboard.
Patch 3 till 11 fix various Orange Pi Win issues, which Samuel posted
before [1]. According to Maxime's comment and with Samuel's permission,
I split them up and integrated them here.
There were reports from people about the Olinuxino board having issues,
so patches 12-14 attempt to fix them.
The NanoPi-A64 also hasn't been updated in a while: enable the Ethernet
and the WiFi/Bluetooth chip, fix a voltage issue and add the LED in the
last four patches.

I don't have the OrangePi, Olinuxino or NanoPi-A64, so can't test these
boards. So even though I have carefully checked the changes against the
available schematics, I would really love to see some testing and
confirmation from owners of these systems.

Cheers,
Andre.

[PATCH v2 01/18] arm64: dts: allwinner: a64: Add L2 cache nodes

[Andre Przywara]

Current kernels complain when booting on an A64 Soc:
....
[    1.904297] cacheinfo: Unable to detect cache hierarchy for CPU 0
....
Not a real biggie on this flat topology, but also easy enough to fix.

Add the L2 cache node and let each CPU point to it.

[PATCH v2 02/18] arm64: dts: allwinner: a64: Add Pine64-LTS device tree file

[Andre Przywara]

The Pine64-LTS is a variant of the Pine64 board, from the software
visible side resembling a SoPine module on a baseboard, though the
board has the SoC and DRAM integrated on one PCB.
Due to this it basically shares the DT with the SoPine baseboard, which
we mimic in our DT by inclucing the boardboard .dts into the new file,
just overwriting the model name.
Having a separate .dts for this seems useful, since we don't know yet if
there are subtle differences between the two. Also the SoC on the LTS
board is technically an "R18" instead of the original "A64", although as
far as we know this is just a relabelled version of the original SoC.

[PATCH v2 04/18] arm64: dts: allwinner: a64: Orange Pi Win: Fix USB

[Andre Przywara]

From: Samuel Holland <samuel@sholland.org>

The Orange Pi Win has 5 USB ports:
Four are standard A sockets, connected to an on-board HUB. The hub's and
socket's power regulators are enabled by GPIO PD7.
Also it features a microB socket, connected to the SoC's USB-OTG port.
It's power is supplied by the AXP PMIC, and the ID pin is connected to
GPIO PH9. It can serve both as a host or a client port.

[PATCH v2 12/18] arm64: dts: allwinner: a64: Olinuxino: fix DRAM voltage

[Andre Przywara]

The Olinuxino board uses DDR3L chips which are supposed to be driven
with 1.35V. The reset default of the AXP is properly set to 1.36V.

While technically the chips can also run at 1.5 volts, changing the
voltage on the fly while booting Linux is asking for trouble. Also
running at a lower voltage saves power.

So fix the DCDC5 value to match the actual board design.

[PATCH v2 14/18] arm64: dts: allwinner: a64: Olinuxino: enable USB

[Andre Przywara]

The Olinuxino has two USB sockets:
USB0 is connected to a micro B socket. As it has the ID pin wired and
the VBUS line connected to the PMIC, we describe it as a proper OTG socket,
which switches between host and device automatically.
USB1 is connected to a normal USB A socket. PG9 enables the power line,
so add the required regulator as well.

[PATCH v2 15/18] arm64: dts: allwinner: a64: NanoPi-A64: Fix DCDC1 voltage

[Andre Przywara]

According to the NanoPi-A64 schematics, DCDC1 is connected to a voltage
rail named "VDD_SYS_3.3V". All users seem to expect 3.3V here: the
Ethernet PHY, the uSD card slot, the camera interface and the GPIO pins
on the headers.
Fix up the voltage on the regulator to lift it up to 3.3V.

[PATCH v2 17/18] arm64: dts: allwinner: a64: NanoPi-A64: Add Wifi/Bluetooth chip

[Andre Przywara]

The NanoPi-A64 has an on-board WiFi/Bluetooth combo chip, connected
to the usual MMC1 and UART1. The AXP power line is the always-on
VDD_SYS_3.3V, but it uses pin L2 to enable the regulator.
As the actual WiFi driver is not in mainline Linux, it doesn't have a
compatible string, so we omit this from the node.

Add the respective nodes to the DT to make it usable.

Again, "Fix USB" is way too dramatic for something that enables the
on-board hub and the USB OTG controller.

Also, two separate patches for this please.

What BT chip is there? Does it have serdev support? If so, that should
be enabled here.

I'd rather not do that. As soon as we'll have OPPs in the DTSI, that
means that cpufreq will be enabled on that board, while no one ever
tested it.

They are already named, so you'd need to explain why that name needs
to be changed.

Same thing for the voltage range, a citation would be useful.

Same thing here, if it has serdev support, then it should have a real
node here.

The NanoPi A64 uses the RTL8189, which does _not_ have Bluetooth.
Something is seriously wrong here.

Yes. A while ago I managed to enable Bluetooth (on the Pine64 with the
same chip), but that involved a lot of hacking with a special userland
tool (not hciattach and no serdev).

What this node means to say is: The UART1 is hardwired to some on-board
device and those pins are not available for GPIO, for instance.

At least that was my understanding when it comes to enabling devices in
the DT. Is that correct?

Cheers,
Andre.

Ah, interesting. You are right that the RTL8189 does not have Bluetooth.
I was just looking at the schematic, which, although naming the
RTL8189ETV there, shows UART1 and PCM connections. The pin numbers are
definitely wrong, it smells like someone copied a RTL8723BS pinout here ;-)

So thanks for the heads up, I will drop the BT/UART part.

Cheers,
Andre.

Well, yes and no. Arguably, any device connected to the other side of
the serial bus should have been there from the beginning. However,
there wasn't any way to do that in Linux before serdev was introduced,
so we weren't doing that. That resulted in hacky userspace tools to
work around that, and other work arounds in the DT to for example
tying BT resources (clock, regulators, resets) to the WiFi chip hoping
that someone would use both all the time.

Now that it's just around the corner, we don't have any excuse to do
these kind of hacks anymore.

That's true. Also I see that the serdev binding itself is not serdev
specific, it just puts the Bluetooth node as a child of an UART node.
But we would still need a compatible string for that child, wouldn't we?
I guess we can't autodetect this? From what I can see from Hans' series
there is no DT compatible string defined?

So do we just put a node there, specifying the resources it needs? Like
the wake-up interrupt or regulators, if any? And leave out the
compatible string, at least for now?

Cheers,
Andre.

did you test? "reg = <1>" on a real hardware ?

I have? "reg = <0>" in my dts? and? it has been working on my board for 
ages.

0 is a wildcard address.

For nano pi, if 1 doesn't work, then it should be 7. 0 can work,
but it won't be accepted by DT maintainers.

reg = <0> is a catch-all for RTL8211. We prefer to have the actual wired
address used here instead of a catch-all.

No, thanks for pointing this out.

According to the PHY's datasheet the PHY address is configured by the
three pins also used for the LEDs. By looking at the schematics back
then I somehow managed to convince myself that it should be 1, as most
other boards use, but from looking again it indeed looks more like 7
(the other LED pin connected to 3.3V).

Can you please try with reg = <7> and confirm that it works that way?

Many thanks,
Andre.

In my memory many nanopi's use 7.

The RTL8211 datasheet, for instance from here:
http://files.pine64.org/doc/datasheet/pine64/rtl8211e(g)-vb(vl)-cg_datasheet_1.6.pdf

Chapter 7.8 explains how the PHY address configuration works. If I match
this with the schematic, it should be 7 indeed.

Cheers,
Andre.

So I tried this:
https://github.com/apritzel/linux/commit/da8e1beadd2737067c#diff-1c31e6cad6646026007c68fe9d4a5079R257

but wasn't really happy with it. Without a proper binding we can't
describe all the resources yet: what's the prefix for -supply, is the
wake-up line a GPIO or an interrupt, is the reset line a GPIO or a reset
property, and so on.

So I can use either an empty node, which would more serve as
documentation, or at least put the wakeup line as an interrupt there.

Was there at least a proposed binding? I tried to look for other BT
chips, but they don't seem to agree on some common properties.

Cheers,
Andre.

A partially empty binding isn't worth anything, since you cannot be
sure it won't change during the review cycle, and you would have to
change it anyway when adding the compatible.

I guess it's fine. I would have liked to postpone this and that we'd
wait for that serie to be merged to create a binding and merge that
patch, but I'm not that reluctant to merge it either.
