The new Khadas VIM2, VIM3 and Edge boards embeds an on-board microcontroller
connected via I2C.

This Microcontroller is present on the Khadas VIM1, VIM2, VIM3 and Edge
boards.

It has multiple boot control features like password check, power-on
options, power-off control and system FAN control on recent boards.

Thie serie adds :
- the bindings
- the MFD driver
- the HWMON cell driver
- the NVMEM cell driver
- updates MAINTAINERS
- add support into the Khadas VIM3/VIM3L DT

Neil Armstrong (8):
  dt-bindings: mfd: add Khadas Microcontroller bindings
  mfd: add support for the Khadas System control Microcontroller
  hwmon: add support for the MCU controlled FAN on Khadas boards
  nvmem: add support for the Khadas MCU Programmable User Memory
  MAINTAINERS: add myself as maintainer for Khadas MCU drivers
  arm64: dts: meson-g12b: move G12B thermal nodes to meson-g12b.dtsi
  arm64: dts: meson-sm1: add cpu thermal nodes
  arm64: dts: meson-khadas-vim3: add Khadas MCU nodes

These two could/should be sent separately from this RFC series and
queued for v5.8.
