Input: Switch i2c drivers back to use .probe()

2023-05-17T16:59:11+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

Input: msg2638 - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

2023-01-10T04:25:27+00:00

SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection
against unused function warnings.  The new combination of pm_sleep_ptr()
and DEFINE_SIMPLE_DEV_PM_OPS() allows the compiler to see the functions,
thus suppressing the warning, but still allowing the unused code to be
removed. Thus also drop the __maybe_unused markings.

Input: msg2638 - only read linux,keycodes array if necessary

2022-11-30T23:16:25+00:00

The linux,keycodes property is optional.
Fix the driver not probing when it's not specified.

Some devices with msg2138 have back/menu/home keys.
Add support for them.

Input: msg2638 - add support for msg2138

2022-11-15T01:13:30+00:00

msg2138 only supports 2 fingers presses, and needs different processing
since second finger press is encoded as a delta position wrt. first one
and the packet/touch_event structs are not the same as msg2638.

Add support for it by implementing distinct structs and irq handler.

Input: msg2638 - set max finger number and irqhandler from driver data

2022-11-15T01:13:27+00:00

This will allow us to add other MStar touchscreen variants' support.
No functional change.

Input: add MStar MSG2638 touchscreen driver

2021-04-10T06:22:38+00:00

Add support for the msg2638 touchscreen IC from MStar.
Firmware handling, wakeup gestures and other specialties are not supported.
This driver reuses zinitix.c structure, while the checksum and irq handler
functions are based on out-of-tree driver for Alcatel Idol 3 (4.7").
