USB2:
The usb2 port only works reliable with:
dr_mode = "host";
Question for Heiko:
Should we change that in rk3328.dtsi or in rk3318-a95x-z2.dts?
///////////////////////////
USB3:
The usb3 port does work with the drivers phy-rockchip-inno-usb3.c and
dwc3-rockchip-inno.c. This work around however still gives a warning for
storage devices..
Disconnect a ttyUSB device gives this log:
[ 25.215260] cp210x 4-1:1.0: cp210x converter detected
[ 25.219970] usb 4-1: cp210x converter now attached to ttyUSB1

When we disconnect a USB Mass Storage device it give a warning about the
cable.

The remote control has 2 buttons for KEY_VOLUMEDOWN and KEY_VOLUMEUP.
The linux definitions have only definitions for 1 key set.
Question:
How can I differentiate between them?
