Subject: [PATCH v2 2/2] dt-bindings: pinctrl: qcom: add msm8953 pinctrl bindings
Add device tree bindings documentation for Qualcomm MSM8953
pinctrl driver.
Signed-off-by: Vladimir Lypak <junak.pub@...il.com>
---
Changes in V2:
- removed "wakeup-parent" property.
- changed pincfg property pattern to '-pins$' and added its description.
- added "serial-pins" subnode to example.
