The PWC IP found in the RZ/V2M family of chips fits the Multi-Function Device (MFD) model quite well, and comes with the below capabilities: * external power supply on/off sequence generation * on/off signal generation for the LPDDR4 core power supply (LPVDD) * key input signals processing * general-purpose output pins With this new version I have changed model for the DT/dt-bindings. I have dropped syscon, simple-mfd, regmap, offset, and the child nodes.
