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 new version of the series merges the 3 drivers from version 2 (MFD core driver, GPIO driver, and poweroff driver) into a single driver.
