2025-02-25Input: apple_z2 - fix potential confusion in KconfigSasha Finkelstein1-2/+2
Add a dependency on ARCH_APPLE and clarify the description to make it more obvious that this is for ARM machines, not x86 ones.

2025-02-25Input: matrix_keypad - use fsleep for delays after activating columnsMarkus Burri1-1/+1
The delay is specified in a device property, so the duration can be arbitrarily large. fsleep() determines the best way of delaying (sleep vs spin) based on duration. see Documentation/timers/delay_sleep_functions.rst Signed-off-by: Markus Burri <markus.burri@mt.com> Reviewed-by: Manuel Traut <manuel.traut@mt.com> Link: https://lore.kernel.org/r/20250110054906.354296-2-markus.burri@mt.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2025-02-25Input: matrix_keypad - add settle time after enabling all columnsMarkus Burri1-0/+6
Matrix keypads with high capacity need a longer settle time after enabling all columns before re-enabling interrupts. The delay gives the system time to settle and avoids spurious interrupts. Add a new optional device property to configure the delay after enabling all columns. The default is no delay.

2025-02-25dt-bindings: input: Correct indentation and style in DTS exampleKrzysztof Kozlowski3-57/+57
DTS example in the bindings should be indented with 2- or 4-spaces and aligned with opening '- |', so correct any differences like 3-spaces or mixtures 2- and 4-spaces in one binding. No functional changes here, but saves some comments during reviews of new patches built on existing code.
