Input: ili210x - add support for polling mode

2026-01-22T00:17:51+00:00

There are designs incorporating Ilitek ILI2xxx touch controller that do not connect interrupt pin, for example Waveshare 13.3" DSI display. To support such systems use polling mode for the input device when I2C client does not have interrupt assigned to it. Factor out ili210x_firmware_update_noirq() to allow conditional scoped guard around this code. The scoped guard has to be applied only in case the IRQ line is connected, and not applied otherwise.

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

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: ili210x - use kvmalloc() to allocate buffer for firmware update

2024-06-28T22:15:08+00:00

Allocating a contiguous buffer of 64K may fail if memory is sufficiently fragmented, and may cause OOM kill of an unrelated process. However we do not need to have contiguous memory. We also do not need to zero out the buffer since it will be overwritten with firmware data. Switch to using kvmalloc() instead of kzalloc().
