Subject: [PATCH 0/4] arm64: dts: rockchip: enable further peripherals on
 ArmSoM Sige5

Add support for the two USB type A ports, link up the CPU regulators for
DVFS, enable WiFi and Bluetooth.

The bluetooth part might warrant some discussion and thoughts from the
list, given that it's connected over UART and thus not discoverable. At
the same time, there are two revisions of the board which have different
Bluetooth chips soldered on: Realtek based on v1.1 and Broadcom based on
v1.2. I'm not sure if there is any way to determine board version from
software. Mine is v1.2, so the respective patch deals with the Broadcom
case only, but maybe it's better to move it into a .dtso and thus kick
the can down the road (i.e. make the user deal with board identification
and loading of the right overlay)? Thoughts welcome.

Best regards,
Alexey
