Subject: [PATCH v4 00/10] RK3588 USBDP support
Hi,
This adds Rockchip RK3588 USBDP PHY support, which is used for two of the three
USB3 controllers in the RK3588 (the third one uses a different PHY, which is
already supported). The USBDP PHY offers USB3 dual-role and DisplayPort. The
driver and bindings being upstreamed contains the DP parts, but only USB3 has
been tested by me (upstream does not yet have a DRM DP bridge driver for this
platform).
What has been tested:
- USB3 Type A ports on Rock 5A, Rock 5B, EVB1
- USB Type C port on EVB1 in Host mode
I did not yet include a patch to enable the Type-C from the Rock 5B, since that
requires enabling proper support for the fusb302. Since the system is usually
supplied via USB-C and without any battery backup, this easily results in
system reset when the power-delivery negotiation happens. As this issue is
independent from the USBDP PHY, I skipped enabling that port on Rock 5B for
now.
You can find a branch with these patches here:

* USBDP PHY DT binding: add Reviewed-by from Conor Dooley

* USBDP PHY driver: add newline after break; in switch cases
* USBDP PHY driver: make some functions void
Changes since PATCHv1:
* https://lore.kernel.org/all/20240209181831.104687-1-sebastian.reichel@collabora.com/
* VO GRF DT binding: Collect Acked-by from Conor Dooley
* USB3 syscon DT binding: Collect Acked-by from Conor Dooley
* USBDP PHY DT binding: fix spelling
* USBDP PHY DT binding: add maxItems: 1 to gpios
* USBDP PHY driver: use rk_udphy_ prefix everywhere
* USBDP PHY DT addition: fix nodenames and property order
* USBDP PHY DT addition: fix position of the GRF nodes
* add new patches fixing existing USB2 PHY nodenames/property order
Not changed:
* rockchip,dp-lane-mux: Why "mux" and not "map"?
- This is about muxing DP lanes vs USB3 lanes. I kept mux instead
of map, since that's used downstream and there does not seem to
be a good reason to diverge?
