Input: chipone_icn8505 - 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: icn8505 - Switch to firmware_request_platform for retreiving the fw

2020-03-20T13:57:54+00:00

Unfortunately sofar we have been unable to get permission to redistribute icn8505 touchscreen firmwares in linux-firmware. This means that people need to find and install the firmware themselves before the touchscreen will work Some UEFI/x86 tablets with an icn8505 touchscreen have a copy of the fw embedded in their UEFI boot-services code. This commit makes the icn8505 driver use the new firmware_request_platform function, which will fallback to looking for such an embedded copy when direct filesystem lookup fails. This will make the touchscreen work OOTB on devices where there is a fw copy embedded in the UEFI code.

Input: add support for ChipOne icn8505 based touchscreens

2018-05-09T20:29:35+00:00

The ChipOne icn8505 is an i2c capacitive touchscreen controller typically used in cheap x86 tablets, this commit adds a driver for it. Note the icn8505 is somewhat similar to the icn8318 and I started with modifying that driver to support both, but in the end the differences were too large and I decided to write a new driver instead.
