Subject: [PATCH v3 0/3] Add pinctrl support for Sky1

Patch 1: Add dt-binding doc for pinctrl on Sky1
Patch 2: Add pin-controller driver for sky1
Patch 3: Add pinctrl nodes for sky1

Changes for v3:
- Pass dts build check with below commands:
make O=$OUTKNL dt_binding_check
make O=$OUTKNL dt_binding_check DT_SCHEMA_FILES=cix,sky1-pinctrl.yaml
scripts/checkpatch.pl 000*.patch
make O=$OUTKNL CHECK_DTBS=y W=1 cix/sky1-orion-o6.dtb
- Re-order the patch set, and move dt-bindings to the 1st patch.
- Refine the pinctrl driver with SKY_PINFUNCTION macro
- Fix warnings when make dt_binding_check

Changes for v2:
- restructure the pinctrl driver to support pinmux=<..>
- redefine pinmux macros
- move header file from dt-bindings to dts
- fix the code-style issues

Gary Yang (3):
  dt-bindings: pinctrl: Add cix,sky1-pinctrl
  pinctrl: cix: Add pin-controller support for sky1
  arm64: dts: cix: Add pinctrl nodes for sky1
