This commit also breaks the touchscreen on the Samsung GT-I9070 mobile phone. All interrupts stop appearing. If I revert the patch I get interrupts.
dmesg after this commit:
$ dmesg |grep mxt [ 1.967816] atmel_mxt_ts 3-004a: Family: 129 Variant: 1 Firmware V1.0.AA Objects: 18 [ 1.975815] atmel_mxt_ts 3-004a: Enabling RETRIGEN workaround [ 1.982398] atmel_mxt_ts 3-004a: Direct firmware load for maxtouch.cfg failed with error -2 [ 1.992252] atmel_mxt_ts 3-004a: Touchscreen size X479Y799
dmesg with commit reverted: $ dmesg |grep mxt [ 1.967831] atmel_mxt_ts 3-004a: Family: 129 Variant: 1 Firmware V1.0.AA Objects: 18 [ 1.984195] atmel_mxt_ts 3-004a: Direct firmware load for maxtouch.cfg failed with error -2 [ 2.007399] atmel_mxt_ts 3-004a: Touchscreen size X479Y799
And I get interrupts.
Tell me if I need to test some more approaches.
Yours, Linus Walleij
