2015-09-27ARM: dts: sun8i: Add pwm-backlight device for A23/A33 Q8 format tabletsChen-Yu Tsai
The LCD backlight on the A23/A33 Q8 format tablets is enabled with a GPIO controlled regulator, and brightness controlled with the SoC's PWM controller. The backlight is powered from the AXP223 PMIC's DC1SW output, which is not supported yet. A proper bootloader is required to enable it. The brightness levels are arbitrary. The FEX files do not have such information. As such, actual brightness levels may differ from device to device.

2015-09-27ARM: dts: sunxi: Add sun?i-q8-common.dtsi files for q8 tabletsHans de Goede
Cheap allwinner based devices in the q8 enclosure come in many variants, all sharing the case and a number of other basic features. They differ in the display, touchscreen, accelerometer and wifi chips used. This commit adds 2 dtsi files defining the shared features of all the q8 tablets. sunxi-q8-common.dtsi defines features shared amongst all q8 tablets, sun8i-q8-common.dtsi defines features shared amongst all a23 / a33 based q8 tablets, but not with a13 q8 based tablets. a13 based tablets use a different card-detect pin for the mmc, and use uart1 instead of the r_uart for the serial console.
