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 This series introduces a driver to address GPIO support, and a driver to address power off support, alongside the corresponding dt-bindings.
