"Why do you think that mlsfw in modalias string has anything to do with loading firmware? I must have misunderstood your statement..." Hi Dmitriy, Its rather guessing based on such disovering: On Chuwi Vi10 rev 11 under Android the only touch related module that is loaded is atmel_mxt_ts while I exactly know (and have firmware too) that in this tablet there is Chipone icn8528.h. (drivers from Windows + dmesg provs this). When you rmmod atmel_mxt_ts the touch still continues to work! I guess someone just used atmel_mxt_ts probably as prototype for detecting (wake uping) chip and loading its firmware and after - no need in any module. According specs of Chipone icn85xx it looks that it even has corresponding mode - to be initialized from firmware and work after with it. It looks weird, but this is the clevest explanation that I could provide - I never seen before such behaviour in Android when there is no dedicated driver for touch screen. In anyway - this is only curiousity, the main goal is simple - to create a driver for icn85xx that wakeup it and loads firmware. I have specs, I have firmware, there is for arm open source drivers (including firmware in .h file): https://github.com/bbelos/rk3188-kernel/blob/master/drivers/input/touchscreen/ICN8503/icn85xx.c Current problem - I could not wake up the chip to obtain its permanent presence on i2c-bus. Regards, Serge Kolotylo.
