Re: [U-Boot] Auto-detecting touchscreen controller and dealing with hw configuration differences on q8 tablets

I'm also a user of an A33 Q8 tablet with GSL1680. However, I think a devicetree-per-device structure is not unacceptable... We can still have sun{5,8}i-q8.common.dtsi, and write most of the q8 codes there. Then the device dt can only contain wifi, touchscreen, accelerometer. (after including s

[U-Boot] Auto-detecting touchscreen controller and dealing with hw configuration differences on q8 tablets

Hi All, The sunxi support in the kernel supports (amongst many other devices) the quite popular low cost q8 form factor 7" tablets. These are all based on the same case, with an allwinner SoC inside (there are non allwinner versions, but those are out of scope) and typically all based on the
