The Point of View protab2-ips9 is a tablet with a 9" ips 1024x768 lcd screen,
microsd slot, headphones, mini hdmi, mini usb b and power barrel connectors.
It uses a rtl8188cus usb wifi chip and a RDA 5875Y bluetooth chip attached
to uart2. It has a bma250 accelerometer attached to i2c1 addr 0x18.
A SD card with sunxi-mmc can fail with the following error message (RCD for

This commits adds a generic dts file for q8 formfactor a13 based tablets.
The tablets ship in many variants, with the difference mainly being the
touchscreen controller / accelerometer / wifi chip used.

This is the sun5i / a13 version of sun8i-q8-common.dtsi for use in dts
files for a13 q8 based tablets. Compared to sun8i this uses uart1 for the

all known q8 a13 devices. This i
