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.

Compared to v5, this version addresses small review comments. I believe
it is ready to go, pending one last review of the PWM side by Uwe. Once
done, I think the simplest course of action is to merge the whole series
through the MFD tree.
