Subject: [PATCH v2 1/4] dt-bindings: pinctrl: qcom: Add SM8550 pinctrl
Add device tree binding Documentation details for Qualcomm SM8550
TLMM device
Signed-off-by: Abel Vesa <abel.vesa@...aro.org>
---
Changes since v1:
* based on recent bindings, like Krzysztof asked
* changed gpio-line-names maxItems to 210
* moved required and additionalProperties below
* dropped *-hog since there are no such nodes yet on SM8550
* switch to double quotes everywhere
* dropped qcom,i2c-pull
* dropped if clause for ^gpio*
* added tlmm label
