I see a lot of Devicetrees wrapping the regulator nodes within a parent node like this
regulators { compatible = "simple-bus"; #address-cells = <1>; #size-cells = <0>; reg_p3v3: regulator@0 { compatible = "regulator-fixed"; [...] regulator-always-on; }; [...]
Contrary to that, patches exist removing the 'regulators' node, because the 'simple-bus' doesn't really exist in hardware. Unfortunately, the documentation is unclear about wrapping regulator nodes like shown above.
Should I avoid the parent 'regulators' node?
Is the given naming schema in fixed-regulator.yaml best practice to follow?
reg_xyz: regulator-xyz { compatible = "regulator-fixed"; regulator-name = "xyz";
Thank you for clarification.
