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 v3, this version addresses small review comments. I believe it is ready to go, pending another review of the PWM side (Uwe reviewed a previous version, and to the best of my knowledge, I've addressed all his concerns) and the MFD driver. Once the PWM driver gets reviewed, I think the simplest course of action is to merge the whole series through the MFD tree.
