move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

Input: chipone_icn8505 - remove an unused field in struct icn8505_data

2024-05-13T21:09:57Z

In "struct icn8505_data", the 'wake_gpio' field is unused. There is also nothing about gpio neither in this driver nor in the data-sheet. So, remove it. Found with cppcheck, unusedStructMember.

Input: Switch i2c drivers back to use .probe()

2023-05-17T16:59:11Z

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: chipone_icn8505 - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

2023-01-10T04:25:24Z

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

2020-03-20T13:57:54Z

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

2018-05-09T20:29:35Z

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.
