I took all three series ( [PATCHv3 0/3] Lost key-up interrupt handling for omap4-keypa [PATCH 1/3] Input: atmel_mxt_ts - use runtime PM instead of [PATCHv5 0/4] n_gsm serdev support and protocol driver for d ) and applied them on top of next-20200320. Good news is that result boots. (So I did partial testing of the patches). Bad news is that I still don't have working backlight. I do have LED and there's backlight device connected to the LED, so I can't control the LED directly, but the screen is black (and I don't see boot messages either). Before I start debugging, does screen work for you in -next, or do you have some fixes I could try?
