Pull input fixes from Dmitry Torokhov: "Just a few driver fixes here" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: elants_i2c - drop zero-checking of ABS_MT_TOUCH_MAJOR resolution Input: elants_i2c - fix division by zero if firmware reports zero phys size Input: nspire-keypad - enable interrupts only when opened Input: i8042 - fix Pegatron C15B ID entry Input: n64joy - fix return value check in n64joy_probe() Input: s6sy761 - fix coordinate read bit shift

Input: elants_i2c - drop zero-checking of ABS_MT_TOUCH_MAJOR resolution

2021-03-29T06:00:17Z

Drop unnecessary zero-checking of ABS_MT_TOUCH_MAJOR resolution since there is no difference between setting resolution to 0 vs not setting it at all. This change makes code cleaner a tad.

Input: elants_i2c - fix division by zero if firmware reports zero phys size

2021-03-28T04:41:09Z

Touchscreen firmware of ASUS Transformer TF700T reports zeros for the phys size. Hence check whether the size is zero and don't set the resolution in this case.

Input: s6sy761 - fix coordinate read bit shift

2021-03-07T23:14:25Z

The touch coordinate register contains the following: byte 3 byte 2 byte 1 +--------+--------+ +-----------------+ +-----------------+ | | | | | | | | X[3:0] | Y[3:0] | | Y[11:4] | | X[11:4] | | | | | | | | +--------+--------+ +-----------------+ +-----------------+ Bytes 2 and 1 need to be shifted left by 4 bits, the least significant nibble of each is stored in byte 3. Currently they are only being shifted by 3 causing the reported coordinates to be incorrect. This matches downstream examples, and has been confirmed on my device (OnePlus 7 Pro).

Input: st1232 - fix NORMAL vs. IDLE state handling

2021-02-23T17:35:33Z

NORMAL (0x0) and IDLE (0x4) are really two different states. Hence you cannot check for both using a bitmask, as that checks for IDLE only, breaking operation for devices that are in NORMAL state. Fix the wait function to report either state as ready.

Prepare input updates for 5.12 merge window.

Merge tag 'v5.11' into next

2021-02-23T05:21:03Z

Merge with mainline to get latest APIs and device tree bindings.

Input: st1232 - add IDLE state as ready condition

2021-02-19T19:03:44Z

The st1232 can switch from NORMAL to IDLE state after the configured idle time (by default 8 s). If the st1232 is not reset during probe, it might already be ready but in IDLE state. Since it does not enter NORMAL state in this case, probe fails. Fix the wait function to report the IDLE state as ready, too.

Input: zinitix - fix return type of zinitix_init_touch()

2021-02-19T19:02:42Z

zinitix_init_touch() returns error code or 0 for success and therefore return type must be int, not bool.
