[PATCH 1/3] ARM: dts: sun4i: Add dts file for Chuwi V7 CW0825 tablet

[Hans de Goede]

The Chuwi V7 is an A10 (sun4i) based tablet with 1G of RAM, 16G of nand flash,
microsd slot, 7" 1024x768 lvds ips panel, mini hdmi out, headphones out,
stereo speakers, front & back camera and usb wifi.

It is clearly marked "CHUWI", "V7" and "Model: CW0825" on the back of the
tablet.

[PATCH 3/3] ARM: dts: sun8i: Add dts file for Ippo Q8H v1.2 tablets

[Hans de Goede]

The Ippo Q8H v1.2 is almost identical to the v5, still it needs a separate
dtb file since some gpio-s surrounding the wlan/bluetooth are different,
it uses different camera sensors, and different DRAM timings.

Note that atm neither the wlan/bluetooth nor the camera are supported, so
atm their is no difference between the dts files, but because of the different
DRAM timings there are already separate u-boot configs for the 2 different
versions, and the 1.2 config refers to sun8i-a23-ippo-q8h-v1.2.dtb to be
future proof, so we need to provide a sun8i-a23-ippo-q8h-v1.2.dtb file.

This is mostly looking good, as usual, but I have a few comments on
it.

This would be great to move to the C-preprocessor includes.

And use the GPIO header for the GPIO flags.

I just merged a patch from Chen-Yu that add a DTSI for the AXP209, you
should probably use it to remove some of the boilerplate.

Would you consider switching to the label-based syntax instead of
replicating the whole DT tree like you did for the A31s DTSI?

Yes, I actually already realized I should have done that mysefl, so I
already have doing a v2 on my todo list. I'll send out a v2 with the
requested changes when I've some time to work on this.

Maybe we should have a separate compatible too then, if we ever need
to differentiate the two for any other reason (quirks, mostly)?

Something like
  compatible = "ippo,q8h-v5", "ippo,q8h", "allwinner,sun8i-a23";
and
  compatible = "ippo,q8h-v1.2", "ippo,q8h", "allwinner,sun8i-a23";

in their respective DTs?
