[PATCH] ARM64: dts: allwinner: Add devicetree for pine H64 modelA evaluation board

[PATCH] ARM64: dts: allwinner: Add devicetree for pine H64 modelA evaluation board

[Corentin Labbe]

This patch adds the evaluation variant of the model A of the PineH64.
The model A has the same size of the pine64 and has a PCIE slot.

The only devicetree difference with current pineH64, is the PHY
regulator.

You also need to add the board in
"Documentation/devicetree/bindings/arm/sunxi.yaml"

I might be missing some context here, but I'm pretty sure that the
initial intent of the pine h64 DTS was to support the model A all
along.

I have Model A board which also needs ddc-en-gpios property for HDMI connector 
in order for HDMI to work correctly. Otherwise it will just use 1024x768 
resolution. Can you confirm that?

The regulator changed between modelA and B.
See this old patchset (supporting modelA) https://patchwork.kernel.org/patch/10539149/ for example.

Sorry I didnt use at all video stuff (like HDMI), so I cannot answer now.

Could you send me a patch against my future v2 and I could test with/without.

I'm not sure what your point is, but mine is that everything about the
model A should be in sun50i-h6-pine-h64.dts.

model A and B are different enough for distinct dtb, (see sub-thread on HDMI difference for an other difference than PHY regulator)
And clearly, the current dtb is for model B.

So do you mean that we need to create a new dtb for model B ? (and hack the current back to model A ?)

I don't have access to my Model A board currently, but this should suffice:

&connector {
	ddc-en-gpios = <&pio 7 2 GPIO_ACTIVE_HIGH>; /* PH2 */
};

I don't mind having separate DTBs for model A and model B.

> And clearly, the current dtb is for model B.

That DTS was added almost a year before the model B was announced, and
no commit to that file mention the model B, so it's definitely not
clear.

I'd prefer not to hack anything, but yes

Normal it was added for model A (without any ethernet/HDMI support, so nothing distinct from model B), and the modelB ethernet/HDMI support cames after.

Since model A is not public (only evaluations boards exists), the probability of a production model A is low and the current dtb is perfect for model B , could you reconsider this ?

Changing the board a DT is meant to halfway through the development is
definitely not ok.

I mean, you could buy it, so it's definitely public.

Model A also had HDMI, and it doesn't look like there's anything
particularly specific with that board.

On the Ethernet side, the only thing that changes is the regulator /
GPIO being used to enable the PHY?

Where ? official pineh64 site speaks only of modelB.

A subthread just say the opposite, modelA need something more for HDMI

Right, but that's not in the DT at the moment.

There're never model A boards that are really sold. When model A is put
on the website, its stock is always 0.

Only model B boards are really sold.

BTW from my communication with TL Lim, model A will get redesigned to
get the software compatiblity with model B, if it's going to be re-
available on the market again. So all known difference will be not
difference between models, but difference between sample version and
final version. But even if the new model A is out, it will still need a
different devicetree with model B, as PCIe is model-A-only feature, and
model A will have no on-board Wi-Fi (model B has RTL8723BS on-board).
