Input: gpio_decoder - don't use "proxy" headers

2026-01-21T20:22:43+00:00

Update header inclusions to follow IWYU (Include What You Use) principle. Signed-off-by: Andy Shevchenko Link: https://patch.msgid.link/20251113154616.3107676-6-andriy.shevchenko@linux.intel.com Signed-off-by: Dmitry Torokhov

Input: gpio_decoder - make use of the macros from bits.h

Make use of BIT() where it makes sense. Signed-off-by: Andy Shevchenko Link: https://patch.msgid.link/20251113154616.3107676-5-andriy.shevchenko@linux.intel.com Signed-off-by: Dmitry Torokhov

Input: gpio_decoder - replace custom loop by gpiod_get_array_value_cansleep()

2026-01-21T20:22:43+00:00

There is a custom loop that repeats parts of gpiod_get_array_value_cansleep(). Use that in conjunction with bitmap API to make code shorter and easier to follow. With this done, add an upper check for amount of GPIOs given based on the driver's code.

Input: gpio_decoder - switch to using polled mode of input devices

2019-10-30T00:15:47+00:00

We have added polled mode to the normal input devices with the intent of retiring input_polled_dev. This converts gpio_decoder driver to use the polling mode of standard input devices and removes dependency on INPUT_POLLDEV.

Input: add generic input driver to read encoded GPIO lines

2016-08-30T03:24:23+00:00

Add a driver to read group of GPIO lines and provide its status as a numerical value as input event to the system. This will help in interfacing devices, that can be connected over GPIOs, that provide input to the system by driving GPIO lines connected to them like a rotary dial or a switch. For example, a rotary switch can be connected to four GPIO lines. The status of the GPIO lines reflect the actual position of the rotary switch dial. For example, if dial points to 9, then the four GPIO lines connected to the switch will read HLLH(0b'1001 = 9). This value can be reported as an ABS_* event to the input subsystem.
