[v4,0/2] 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

Version 4 of this series basically just moves the dt-bindings
file under Documentation/devicetree/bindings/soc/renesas.

Thanks,
Fab

The subject line now needs changing.

This patch doesn't have anything to do with MFD.

Doh, you are absolutely right, I'll send a v5 to address that.
