[PATCH 0/4] arm64: dts: allwinner: Add Anbernic RG35XX (Plus/H/2024) support

[PATCH 0/4] arm64: dts: allwinner: Add Anbernic RG35XX (Plus/H/2024) support

[Ryan Walklin]

From: Ryan Walklin <ryan@testtoast.com>

The Anbernic RG35XX is a family of handheld gaming devices. There are 4 
variants, of which 3 using the Allwinner H700 chip are covered by this patchset.
The fourth (released first and named simply RG35XX) uses an Actions 
Semiconductor ATM7039s which is a 32-bit Cortex-A9 chip with no mainline support 
and is not covered.

Common features (RG35XX-2024):
- Allwinner H700 @ 1.5GHz (H616 variant exposing RGB LCD pins, with 4x 
  Cortex-A53 Cores and a Mali G31 GPU)
- 1 GB LPDDR4 DRAM
- AXP717 PMIC (patches accepted in mfd-next - 
  https://kernel.googlesource.com/pub/scm/linux/kernel/git/lee/mfd/+/d2ac3df75c3a995064cfac0171e082a30d8c4c66)
- 3.5" 640x480 RGB LCD
- Mini-HDMI, 3.5mm audio jack, mono speaker, two microSD slots and USB-C 
  (USB 2.0) for power.

RG35XX-Plus adds:
- RTL8821CS SDIO Wifi/BT chip

RG35XX-H (Horizontal form-factor) adds:
- RTL8821CS SDIO Wifi/BT chip
- Two analog thumbsticks
- Second USB-C port
- Stereo speaker

Patch 1 adds the DT bindings for the board names, Patch 2 adds the -2024 device
as a common base, Patch 3 adds Wifi/BT support for the -Plus (and -H), and Patch 
3 adds the second USB and thumbsticks for the -H. The -H is a strict superset of
the -Plus, which is in turn a strict superset of the -2024, so this translates 
quite neatly. Alternatively a single DTS for the three devices could be 
considered.

LCD, HDMI, audio and GPU support are not yet ready and relying on out-of-tree 
patches currently, so will be added once these drivers are mainlined.

Any reason these are not just one enum with three entires?

Thanks for the review and feedback.

No, this is just to match the existing devices, are you able to point to an example elsewhere?

Even for variants of same boards?

The examples are everywhere, e.g. Qualcomm or NXP.

We have separate entries for closely related boards (Pine64 H64 model A
and B), and also indeed for updated variants (the various PinePhone
revisions).
That doesn't need the stay this way, of course. We would lose a quite
natural way of putting a descriptive name to each compatible string (cf.
"Pine64 PinePhone Developer Batch (1.0)"), but if the main purpose of this
file is to *reserve* the compatible strings, it would indeed be shorter to
use enums for related boards.
Don't know if this would a real advantage, though.

Cheers,
Andre

If this matches your existing practice, then it is perfectly fine for
me. I will probably still be bringing up this question from time to
time, because for me it blows the binding unnecessarily making it harder
to maintain/read, but that's only matter of taste.

Krzysztof

I think the policy in *this* file is one entry for each device, so that we
can attribute a device name ("Anbernic RG35XX H") to the compatible string.
I mean otherwise we could group all H616 boards for instance into one
entry. Don't know if this is what we want?

Cheers,
Andre

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).

No uppercase letters are allowed as node names.

Although it is allowed but not consistent and readable.

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:

Keep test and dead code outside upstream submission.

We don't put aliases for MMC devices in here. Conceptually they should
not be needed, but U-Boot will add them automatically anyway, so we
would not lose anything.

This last line is not be needed, since that regulator is not switchable
anyways.
Also can you please add a comment that this is the USB-C power input?

So what is this gpio? Please specify it in this node.

Assuming this is the regulator that provides the USB-VBUS power on
the USB-C connector, then we should not force it on. I think the boot
state is actually off, to allow power input from that socket, and to
enable USB-OTG functionality, for instance for FEL mode.
We should reference this regulator in the USB-PHY mode instead, then
it would be automatically enabled if needed, see below.

Is that just for the second SD card? You should name it then
accordingly.

Please add the usual comment stating the GPIO name here.

Again those two properties should not be here, unless this really
powers something essential, that we cannot control otherwise. But since
it's GPIO controlled, I doubt that.

What is this regulator for? Is it really a separate fixed regulator, or
actually one rail from the AXP?

Regardless of the above, it looks like only being referenced by the
WiFi chip, and then it should not be always on, I guess?

So which one is it? If the former, please just remove that commented

Regardless of whether the interrupts really work, you would need both
of those properties.

So this should be the NMI controller that Chris is looking at, right?
Anyway, please no commented lines without a good reason. And it looks
like it wouldn't be "r_intc" in any case.
If you want to drop support for now, but give a hint, please do this in
a normal free form comment.

I don't think boot-on helps here, please just drop it. The same applies
to the other cases in this file. Unless you have a good reason ...

I guess this needs to be increased slightly, to cover the BSP OPP
table entry for 1.5 GHz?

So is that the regulator exclusively used for the second SD card?
Then you wouldn't need the always-on and boot-on properties.
And then it should be referenced in the PIO's vcc-pc-supply.

So I don't see any of those following regulators (minus cldo4)
referenced in the DTs, and with that given broad voltage range I don't
think those entries are useful anyway.
So can you remove/disable/comment all of them, and see if the device
still works, or what functionality goes missing?
If we don't need them, just remove the respective nodes altogether.

I dimly remember that this rail was used by some critical device? Or
for one of the mandatory 1.8V supply pins on the SoC?
So this might be only one that needs to stay, I guess.

If this is for the WiFi chip, it should not be always-on.

So is that connected directly to the USB power pins? Or is there a
GPIO controlled switch in between?
If it's the latter, this rail should be referenced above in the
vcc_5v0_usb regulator, via the "vin-supply" property.

Same here, do we need this regulator at all, and does it really need to
be always-on?

If there is a regulator controlling the USB VBUS pins, you would
reference it here:
	usb0_vbus-supply = <&vcc_5v0_usb>;

For the -H model with its second USB port it's usb1_vbus-supply,
respectively.

That regulator should then also provide the PIO's vcc-pg-supply. And
maybe it should be renamed.

That would be redundant, as the node is already contained in the base
.dts?

As usual, please add the GPIO names as a comment.

Same as in 3/4: redundant line.

Is it intended to be in a separate node from the other keys? Just
reference the existing node (below, outside of the root node) and add
the keys in there.

I missed that in the first DTS, but you should move the 'status =
"okay";' lines for EHCI1/OHCI1 from patch 2/4 into here, since the
second USB port should stay disabled on those other two boards.

That looks odd. I do understand that a second USB port allows the
first to be dedicated to OTG, but I feels still weird that the default
for the only one on the other two boards is host.
Can you say what the expected use case is? Are people connecting things
like controllers to the only USB port? Otherwise I would expect this
more to be a charging port, to which peripheral would be a better fit.
I guess ultimately this would be "otg", but we need the AXP717 USB-C
support for that, which is not ready yet.

If there is an enable GPIO for VBUS, then the respective regulator
should be referenced here.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade
