Hi everyone,
This series add support for MSI's Primo73 tablet. This is a 7" tablet based on Allwinner's A20 SoC.
The tablet uses some unknown LCD panel, with only serial number markings, and what appears to be a part number. Searching the Internet for said part number yielded no usable results. Hence this panel is described solely using the panel-dpi binding. The display timing values were retrieved from the hardware description file from the original Android system.
A new property for the panel-dpi binding is added to describe the color depth of the panel, which is normally included the panel description in panel-simple. Otherwise this would be undefined in the panel-dpi case and left to encoder drivers to make up. I believe this would be separate from the bus format, which was added earlier and then retracted.
Patches 1 and 2 add the new color depth property to the device tree binding and the panel-simple driver.
Patch 3 adds the board compatible string to the list of boards.
Patch 4 adds a pinmux option for LCD0 full 24-bit output, with control signals, for the A20.
Patch 5 adds the device tree file for the Primo73.
Please have a look.
Regards ChenYu
