Merge tag 'input-for-v6.19-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:

- DT bindings for Melfas MIP4 touchscreen controller and TWL4030 keypad
have been converted to the DT schema

- simple touch controller bindings have been consolidated to
trivial-touch.yaml DT schema

- memory allocation failure noise was removed from qnap-mcu-input and
zforce_ts dirvers

- ti_am335x_tsc driver was hardened to handle invalid (too large)
number of coordinates specified in device tree

- a cleanup in Cypress cyttsp5 driver to use %pe to print error code

* tag 'input-for-v6.19-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: ti_am335x_tsc - clamp coordinate_readouts to DT maximum (6)
