Although I wont insist on that since > the regulators are optional properties. > In the patch comment I stated it relied on the dummy regulator as the codec is always on but maybe I should have been more precise: it is not out of convenience to keep things on, it is by HW design: I mentioned it in the comment of "ARM: dts: da850: Add basic DTS for the LCDK": "the main PMIC, different and hard-wired on the LCDK (the LDOs and DCDCs are always on)" after reviewing the schematics. I could add that in the patch comment. Thanks for reviewing.
