[PATCH 2/7] Input: s6sy761 - split into core and I2C modules
Lukas Timmermann
foss at timmermann.space
Sun Oct 11 05:44:57 PDT 2026
Split this driver into a bus-agnostic core and I2C transport part in
preparation for adding SPI support. Also add a mutex because the
driver now has a transfer buffer shared between IRQ, sysfs
and PM threads.
The Kconfig is backwards-compatible and should work on boards with an
S6SY761 touchscreen as before. The I2C transfers of the driver should be
byte by byte identical.
The modules are now called s6sy761_core and s6sy761_i2c.
