Subject: [PATCH v3 0/3] Add ZynqMP pinctrl driver

Add support for Xilinx ZynqMP pinctrl driver and also update the
Xilinx firmware driver to support pinctrl functionality.
This driver queries the pin information from the firmware and
allow configuring the pins as per the request.

changes in v3:
- Fixed binding doc comments from Rob.
- Used 'maxItems' for groups and pins properties.
- Updated commit subject and description to have
present tense statements.

changes in v2:
- Use pattern for pin names in yaml file.
- Updated to support multiple groups and pins.
- Added type ref for the vendor specific properties.
- Removed 'schmitt-cmos', instead used common properties.
- Removed macros for drive-strength property.
