Subject: [PATCH v2 0/4] 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

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.

Thanks,
Fab

Fabrizio Castro (4):
  dt-bindings: mfd: Add RZ/V2M PWC
  mfd: Add RZ/V2M PWC core driver
  gpio: Add support for the Renesas RZ/V2M PWC GPIOs
  power: reset: Add new driver for RZ/V2M PWC poweroff
