[PATCH v2 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 v2 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.
