Convert the bindings of Qualcomm SPMI regulators to DT schema. Signed-off-by: Robert Marko <robimarko@gmail.com> --- I am aware that syscon alone is not really acceptable, its converted directly from the old text bindings. There is also the issue of some MSM8994, MSM8996 and APQ8096 devices using '#address-cells', '#size-cells', some even defining reg property for regulators. Any advice on how to solve these issues is appreciated. Changes in v2: * Remove the forgotten text bindings * Move allOf after patternProperties * Use my private email as the maintainer email --- .../regulator/qcom,spmi-regulator.txt | 347 ------------------ .../regulator/qcom,spmi-regulator.yaml | 176 +++++++++ 2 files changed, 176 insertions(+), 347 deletions(-) delete mode 100644 Documentation/devicetree/bindings/regulator/qcom,spmi-regulator.txt create mode 100644 Documentation/devicetree/bindings/regulator/qcom,spmi-regulator.yaml
