Input: tm2-touchkey - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

2022-12-07T21:27:23+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. Signed-off-by: Jonathan Cameron Link: https://lore.kernel.org/r/20221204180841.2211588-13-jic23@kernel.org Signed-off-by: Dmitry Torokhov

Input: tm2-touchkey - Convert to i2c's .probe_new()

2022-12-02T22:53:42+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/20221118224540.619276-206-uwe@kleine-koenig.org Signed-off-by: Dmitry Torokhov

Input: tm2-touchkey - allow changing keycodes from userspace

2021-10-16T03:26:30+00:00

At the moment the touch keys have key codes assigned from the device tree. In some cases, users might want to change the key code from userspace. There is existing functionality for this in the input core using the EVIOCSKEYCODE ioctl, which is integrated for example into udev. Make it possible to use this functionality for tm2-touchkey by simply making the input core aware of the array that holds the keycodes. Similar code also exists in mcs_touchkey and mpr121_touchkey.

Input: tm2-touchkey - report scan codes

2021-10-16T03:26:30+00:00

Report the index of pressed touch key as MSC_SCAN code to userspace so it is possible to identify which of the keys was pressed (not just the function that is currently assigned to the key). This is done similarly also in mcs_touchkey and mpr121_touchkey.

Input: tm2-touchkey - add vddio regulator

2020-12-10T03:47:11+00:00

The Samsung touchkey controllers are often used with external pull-up for the interrupt line and the I2C lines, so we might need to enable a regulator to bring the lines into usable state. Otherwise, this might cause spurious interrupts and reading from I2C will fail. Implement support for a "vddio-supply" that is enabled by the tm2-touchkey driver so that the regulator gets enabled when needed.

Input: tm2-touchkey - add support for Coreriver TC360 variant

The Coreriver TouchCore 360 is like the midas board touchkey, but it is using a fixed regulator. Signed-off-by: Nick Reitemeyer Link: https://lore.kernel.org/r/20200121141525.3404-3-nick.reitemeyer@web.de Signed-off-by: Dmitry Torokhov

Input: tm2-touchkey - acknowledge that setting brightness is a blocking call

2019-02-08T07:41:12+00:00

We need to access I2C bus when switching brightness, and that may block, therefore we have to set stmfts_brightness_set() as LED's brightness_set_blocking() method. Fixes: 72d1f2346ded ("Input: tm2-touchkey - add touchkey driver support for TM2") Acked-by: Andi Shyti Signed-off-by: Dmitry Torokhov

Input: tm2-touchkey - allow specifying custom keycodes

2019-01-07T19:49:41+00:00

Not all devices use the same keycodes in the same order, so add possibility to define keycodes for buttons present on actual hardware. If keycodes property is not present, we assume that device has at least MENU and BACK keys. Signed-off-by: Jonathan Bakker Signed-off-by: Paweł Chmiel Signed-off-by: Dmitry Torokhov
