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.

Thanks,
Fab

Fabrizio Castro (5):
  dt-bindings: gpio: Add RZ/V2M PWC GPIO driver bindings
  dt-bindings: power: reset: Add RZ/V2M PWC Power OFF bindings
  dt-bindings: mfd: Add RZ/V2M PWC global registers bindings
  gpio: Add support for Renesas RZ/V2M PWC
  power: reset: Add new driver for RZ/V2M PWC poweroff
