[ Upstream commit c0ca3dbd03d66c6b9e044f48720e6ab5cef37ae5 ]
Instead of manually extracting certain bits from registers with binary
ANDs and shifts, the FIELD_GET macro can be used. With this in mind, the
*_SHIFT macros can be dropped.

input/touchscreen: imagis: Correct the maximum touch area value2024-04-13T11:07:36+00:00Markuss Broksmarkuss.broks@gmail.com2024-03-01T16:41:00+00:00urn:sha1:44723bd493cd491a1f03664df61f5d120cb63a08
[ Upstream commit 54a62ed17a705ef1ac80ebca2b62136b19243e19 ]
As specified in downstream IST3038B driver and proved by testing,
the correct maximum reported value of touch area is 16.

Input: Switch i2c drivers back to use .probe()2023-05-17T16:59:11+00:00Uwe Kleine-Königu.kleine-koenig@pengutronix.de2023-05-17T16:55:42+00:00urn:sha1:d8bde56dfd86a0bba9206de8574e58c8aaac4f0f
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: imagis - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()2023-01-10T04:25:26+00:00Jonathan CameronJonathan.Cameron@huawei.com2023-01-02T18:18:22+00:00urn:sha1:a9b113302ca684e4335f9c7ae5a3b78b08030760
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: add Imagis touchscreen driver2022-03-21T05:00:12+00:00Markuss Broksmarkuss.broks@gmail.com2022-03-15T05:56:19+00:00urn:sha1:a23ba3c043db9a2e8c967a3ff66dcedc5725afdf
Add support for the IST3038C touchscreen IC from Imagis, based on
downstream driver. The driver supports multi-touch (10 touch points)
The IST3038C IC supports touch keys, but the support isn't added
because the touch screen used for testing doesn't utilize touch keys.
Looking at the downstream driver, it is possible to add support
for other Imagis ICs of IST30**C series.
