In preparation of new sdm660-mainline kernel release all downstream ports will become irrelevant. If needed, downstream port can still be chosen as 'xiaomi-lavender-downstream' during pmbootstrap init.

Subject: [PATCH] driver: touchscreen: nvt_touch_f7a: do not report
|
|
ABS_MT_TOUCH_MAJOR/ABS_MT_WIDTH_MAJOR
|
|
|
|
It seems touchscreen chip can only report touch pressure from 0 to 255,
|
|
which should be ABS_MT_PRESSURE according to
|
|
https://www.kernel.org/doc/Documentation/input/multi-touch-protocol.txt.
|
|
|
|
Do not set same values to ABS_MT_TOUCH_MAJOR/ABS_MT_WIDTH_MAJOR to avoid
|
|
breaking libinput and software.
|
|
|
|
Thanks @NotKit!
