Subject: arm64: dts: rockchip: use USB host by default on rk3399-rock-pi-4
|
|
|
|
Based on the board schematics at
|
|
https://dl.radxa.com/rockpi4/docs/hw/rockpi4/rockpi_4c_v12_sch_20200620.pdf
|
|
on page 19 there is an USB Type-A receptacle being used as an USB-OTG port.
|
|
|
|
But the Type-A connector is not valid for OTG operation, for this reason
|
|
there is a switch to select host or device role.
|
|
This is non-compliant and error prone because switching is manual.
|
|
So, use host mode as it corresponds for a Type-A receptacle.
