[PATCH v2 6/6] ARM: sun8i: dts: Add Ippo-q8h v1.2 with A33 and 1024x600 lcd support

[Hans de Goede]

The Ippo-q8h is a tablet circuit board commonly found in cheap Android
tablets. The v1.2 version can be used with either an A23 or A33 SoC.

This adds a dts file for the v1.2 board with an A33 SoC and a 1024x600
LCD screen (most of these tablets have a 800x480 screen).

This version features 512 MB DRAM, 4G NAND, MMC, LCD, capacitive
touchscreen, accelerometer, 2 camera sensors, USB OTG, microphone
and speakers.

i2c0 is connected to the gsl1680 capacitive touch panel controller,
i2c1 is connected to an mma7660 3-axis accelerometer, these peripherals are
not supported by the kernel yet, i2c bus functionality has been tested via
i2c-dev.
