Subject: [PATCH v3 0/2] Driver support for RZ/V2M PWC

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.

Thanks,
Fab
