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

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 adds this dynamic switching right before booting Linux.

This file doesn't exist in this series, so it doesn't compile.
Copying it from Linux, it compiles and works fine.
