[PATCH v2 0/4] ADP5585 GPIO expander, PWM and keypad controller support

From: Laurent Pinchart
Date: Tue May 28 2024 - 15:03:37 EST


Hello,

This patch series introduces support for the Analog Devices ADP5585, a
GPIO expander, PWM and keyboard controller. It models the chip as an MFD
device, and includes DT bindings (1/4), an MFD driver (2/4) and drivers
for the GPIO (3/4) and PWM (4/4) functions.

Support for the keypad controller is left out, as I have no means to
test it at the moment. The chip also includes a tiny reset controller,
as well as a 3-bit input programmable logic block, which I haven't tried
to support (and also have no means to test).

The driver is based on an initial version from the NXP BSP kernel, then
extensively and nearly completely rewritten, with added DT bindings. I
have nonetheless retained original authorship. Clark, Haibo, if you
would prefer not being credited and/or listed as authors, please let me
know.

All review comments from v1 have been taken into account as far as I can
tell. The most notable changes are in the DT binding that now merge all
functions in a single node, and the corresponding changes to the
drivers.
