[PATCH 0/2] Add support for the dual-role dwc3 controllers on rk3588-tiger

[Heiko Stuebner]

A comment fix and then the addition of the nodes for the dwc3 controllers
using the newly merged usbdp phys.

[PATCH 1/2] arm64: dts: rockchip: fix comment for upper usb3 port

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

The comment for the host2_xhci points to the wrong port on the board.
The upper usb3 port is the correct one, so fix the comment to prevent
confusion.

Missing the same update to the comments above &usb_host0_ohci and 
&usb_host0_ehci.

[PATCH 2/2] arm64: dts: rockchip: add dual-role usb3 hosts to rk3588 Tiger-Haikou

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

Apart from the host-only usb3 controller (host2) the rk3588 also provides
two dual-role controllers. On the Tiger-Haikou combination these are
connected to the lower usb3-host port in host-only mode and the micro-usb3
port for dual-role operation.

Add the necessary controllers, phys and usb-id extcon to the Tiger-Haikou
board. The Q7 standard defines the pin as usb-id, but it will only ever
get used if the baseboard actually provides an OTG port. So the extcon
stays disabled in the dtsi and only gets enabled in the haikou dts.

Would have preferred two separate commits but the content is fine and 
it's not that difficult to review, so

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


New warnings running 'make CHECK_DTBS=y rockchip/rk3588-tiger-haikou.dtb' for 20240418210332.2394871-1-heiko@sntech.de:

This follows the txt-binding from
	https://www.kernel.org/doc/Documentation/devicetree/bindings/extcon/extcon-usb-gpio.txt
so in mainline there is no yaml binding yet for the usb-id-extcon.

Though I did find a still pending yaml conversion for it in
	https://lore.kernel.org/linux-arm-kernel/20240215093214.796821-1-alexander.stein@ew.tq-group.com/T/

Though not sure what the holdup is there as it got a Review from you?
Can you just pick this for the main dt-tree?


Heiko
