Subject: [PATCH 0/4] pinctrl: pinctrl-zynq: yaml conversion and minor driver updates

This patch series does the following
- Covert Zynq pinctrl driver binding file to yaml.
- Update the binding for Zynq pinctrl to replace the 'io-standard' with
'power-source' parameter as recommended by Linus during ZynqMP pinctrl
driver review(https://lkml.org/lkml/2021/3/25/278).
- Update the Zynq pinctrl the driver to remove custom pin
parameter(io-standard) and instead use generic parameter(power-source).
- Update Zynq dts files to replace 'io-standard' with 'power-source'.

Reason for adding the generic parameter 'power-source' in Zynq pinctrl driver
is to maintain common pin parameter across Xilinx Zynq and ZynqMP platforms
for power supply configuration.

Sai Krishna Potthuri (4):
  dt-bindings: pinctrl: pinctrl-zynq: Convert to yaml
  dt-bindings: pinctrl-zynq: Replace 'io-standard' with 'power-source'
  pinctrl: pinctrl-zynq: Add support for 'power-source' parameter
  arm: dts: zynq: Replace 'io-standard' with 'power-source' property
