[PATCH] arm64: dts: rockchip: orangepi-5-plus: Enable USB 3.0 ports
Posted by Chen-Yu Tsai 1 month ago
From: Chen-Yu Tsai <wens@csie.org>

The Orange Pi 5 Plus has its first USB 3.0 interface on the SoC wired
directly to the USB type C port next to the MASKROM button, and the
second interface wired to a USB 3.0 hub which in turn is connected to
the USB 3.0 host ports on the board, as well as the USB 2.0 connection
on the M.2 E-key slot.

CCing the DTS author would be nice. :)

Thanks for submitting this. I found a few issues. See below:

This is named vbus5v0_typec in the schematic.

The board can't sink power from this port. It's a source only port. So sink-pdos
can be lower, so that if you plug this into type-c hub as a peripheral, the hub
doesn't need to reserve 5W for this port.

op-sink-microwat can also be lower. The port will not sink any power when
connected to 5V VBUS externally.

Otherwise you can probably keep power-role = "dual";

This port can't source 3A. U22 (SY6280AAC) is configured via Rset for 1.44A
limit. So let's say 1.5A.

This is the default. No need to have it here.

I guess it should just be power-role = "source";
And then drop all the sink related properties.

Probably 1.4A to be safe?

You probably mean vcc5v0_sys?

The power switch that feeds the ports is controlled by the hub directly.
The hub is powered off vcc5v0_sys.

Ack.

Probably not. The board is not powered from that port, but I should still be able
to plug it via that port to a PC, and in that case it should not act as power
source (vbus should be disabled), because PC's port will provide power. (say
via USB-A <-> USB-C cable connected to PC's USB host port)

It should still be capable of being in power sink mode on that port, but it will
just not physically sink anything. Just the board's vbus will be disabled.

We should just describe that in sink mode it will not sink much of anything.

Sorry, ignore this request completely. I was mis-looking at quartzpro DTS, when
reviewing this part of the patch.

Thank you,
