Hello, This series adds support for the Maxim 77663 chip that provides PMIC, RTC, GPIO and watchdog timer functionality. The hardware is very similar to the Maxim 77620/20024 hardware units that are already supported by the kernel, hence we will reuse the existing drivers for 77663. The GPIO, regulator, RTC and watchdog timer functionality was tested on a Nexus 7 tablet that has the Max77663 chip, everything is working perfectly fine. I'm looking at upstreaming support for that tablet device and Max77663 is one of the core components that are currently missing in the upstream kernel. Changelog: v4: Addressed review comments from Rob Herring to v3 by making use of generic "system-power-controller" property and making couple other minor cosmetic changes. Added Mark's Brown a-b to the regulator-patch. v3: Dropped "Support device-tree properly" patch since turned out that I2C core takes care of the device-tree matching and I wasn't aware of it. v2: Added PINCTRL sub-device to Max77663 MFD as it looks compatible with 77620. Added new "maxim,system-power-controller" OF property. Patch "Support device-tree properly" now doesn't remove driver's "id_table" since potentially it could have some use in the downstream kernel forks and it doesn't hurt to keep it around.
