Hi, Changes in v5: - Refactor the pinctrl target files based on the new macro and structure defined as suggested by Andy. Changes in v4: - Fixed the bindings check and rebased on linux-next. Changes in v3: - Rebased the bindings on linux-next as suggested by Krzysztof. Changes in v2: - Updated the bindings to clear the bindings check. This patch series adds pinctrl bindings and tlmm support for SDX75. Thanks, Rohit.
