[PATCH v2] dt-bindings: pinctrl: qcom: move gpio-hog schema to tlmm-common

[PATCH v2] dt-bindings: pinctrl: qcom: move gpio-hog schema to tlmm-common

[Swati Agarwal]

Qualcomm TLMM-based pin controllers share the same gpio-hog binding
semantics across multiple SoCs. The gpio-hog pattern currently defined in
qcom,sdm845-pinctrl.yaml is not specific to SDM845 and applies to all TLMM
controllers.

Move the gpio-hog patternProperties definition to qcom,tlmm-common.yaml so
that it can be reused by other Qualcomm TLMM pinctrl bindings and avoid
duplication.

Please also remove it from qcom,ipq4019-pinctrl, which also includes
tlmm-common

Does not look like v1. That's a DTS patch.

Best regards,
Krzysztof

Hi Krzysztof,

Yes that's correct, v1 is a patch to DTS.
But in v1 , I received comment from Dmitry to move gpio hog bindings
to qcom,tlmm-common.yaml [1] so just gave reference to that v1 version
and splitted DT bindings and DTS patch patch[2].
