Subject: [PATCH 1/6] dt-bindings: regulator: qcom,spmi-regulator: Convert to dtschema
Convert the bindings of Qualcomm SPMI regulators to DT schema.
Signed-off-by: Robert Marko <robimarko@...il.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.
