[PATCH v2 0/4] amlogic: vim3: add support for dynamic PCIe enable

[Neil Armstrong]

The VIM3 on-board  MCU can mux the PCIe/USB3.0 shared differential
lines using a FUSB340TMX USB 3.1 SuperSpeed Data Switch between
an USB3.0 Type A connector and a M.2 Key M slot.
The PHY driving these differential lines is shared between
the USB3.0 controller and the PCIe Controller, thus only
a single controller can use it.

This serie adds a VIM3 specific board support and adds this dynamic
switching right before booting Linux.

Changes since v1:
- add missing khadas-mcu.h
- add documentation to switch pcie on/off

Neil Armstrong (4):
  ARM: dts: sync amlogic G12A/SM1 DT from Linux 5.9-rc1
  board: amlogic: add a vim3 specific board support
  configs: vim3: use the vim3 board support
  board: amlogic: vim3: add support for dynamic PCIe enable
