Subject: [PATCH v2 0/9] add support for pf1550 PMIC MFD-based drivers

This series adds support for pf1550 PMIC. It provides the core mfd driver and a
set of three sub-drivers for the regulator, power supply and input subsystems.

Patches 1-4 add the DT binding documents. Patches 5-8 add all drivers. Last
patch adds a MAINTAINERS entry for this device.

Changes since v1 [1]:
   1. DT bindings for all devices included
   2. Add onkey driver
   3. Add driver for the regulators
   4. Ensure charger is activated as some variants have it off by default
   5. Update mfd and charger driver per feedback from eballetbo@...il.com
   6. Add myself as maintainer for these drivers

[1]: v1: https://lore.kernel.org/1523974819-8711-1-git-send-email-abel.vesa@nxp.com/
