Input: cy8ctma140 - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

2023-01-10T04:25:24+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: cy8ctma140 - Convert to i2c's .probe_new()

2022-12-02T22:53:44+00:00

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20221118224540.619276-233-uwe@kleine-koenig.org Signed-off-by: Dmitry Torokhov

Input: add driver for the Cypress CY8CTMA140 touchscreen

2020-05-10T05:26:48+00:00

This adds a new driver for the Cypress CY8CTMA140 touchscreen. This driver is inspired by out-of-tree code for the Samsung GT-S7710 mobile phone. I have tried to compare the structure and behaviour of this touchscreen to the existing CYTTSP and CYTTSP4 generics and it seems pretty different. It is also different in character from the cy8ctmg110_ts.c. It appears to rather be vaguely related to the Melfas MMS114 driver, yet distinctly different. Dmitry Torokhov rewrote the key scanning code during the submission process so the driver is a joint work.
