From: Sumit Garg Date: Wed, 27 Jul 2022 08:22:04 +0000 (+0530) Subject: arm: dts: qcom: Sync pinctrl DT nodes with Linux bindings X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=0ddabb6830e5aee2c54f86f2430ea0f28f7538c3;p=u-boot.git arm: dts: qcom: Sync pinctrl DT nodes with Linux bindings Currently for all Qcom SoCs/boards there are separate compatibles for GPIO and pinctrl. But this is inconsistent with official (upstream) Linux bindings which requires only a single compatible "qcom,-pinctrl" and there is no such compatible property as "qcom,tlmm-". So fix this inconsistency for Qcom SoCs in order to comply with upstream DT bindings. This is done via removing compatibles from "msm_gpio" driver and via binding to "msm_gpio" driver from pinctrl driver in case "gpio-controller" property is specified for pinctrl node.
