[PATCH v1 00/10] RK3588 USBDP support

[PATCH v1 00/10] RK3588 USBDP support

[Sebastian Reichel]

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 by me:
 - 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:

https://gitlab.collabora.com/hardware-enablement/rockchip-3588/linux/-/commits/rk3588-usbdp

The binding updates introduces one DT warning, for vo1 grf, which is already
upstream and does not describe its clock. Fixing that requires this series,
which adds the necessary clock ID for vo1:

[PATCH v1 01/10] dt-bindings: soc: rockchip: add clock to RK3588 VO grf

[Sebastian Reichel]

The RK3588 VO GRF needs a clock. This adds the clock to the allowed
properties, makes it mandatory for the RK3588 VO grf and disallows it
for any other Rockchip grf.

If we are talking nits, the first use of "dp" should be "DisplayPort (DP)"
and s/dp/DP/ elsewhere.

"If DP lanes are mapped by" "not needed."

[PATCH v1 04/10] phy: rockchip: add usbdp combo phy driver

[Sebastian Reichel]

This adds a new USBDP combo PHY with Samsung IP block driver.

The driver get lane mux and mapping info in 2 ways, supporting
DisplayPort alternate mode or parsing from DT. When parsing from DT,
the property "rockchip,dp-lane-mux" provide the DP mux and mapping
info. This is needed when the PHY is not used with TypeC Alt-Mode.
For example if the USB3 interface of the PHY is connected to a USB
Type A connector and the DP interface is connected to a DisplayPort
connector.

When do DP link training, need to set lane number, link rate, swing,
and pre-emphasis via PHY configure interface.

For Linux FTRACE filters it is needed that all functions in a driver start with the same function prefix.
Currently there's a mix of udphy_* and rockchip_*
Maybe use rk_udphy_* ??? similar to for example rk_nfc_* in rockchip-nand-controller.c

[PATCH v1 05/10] arm64: defconfig: enable Rockchip Samsung USBDP PHY

[Sebastian Reichel]

The USBDP Phy is used by RK3588 to handle the Dual-Role USB3
controllers. The Phy also supports Displayport Alt-Mode, but
the necessary DRM driver has not yet been merged.

Align with the (new) documentation
about property ordering.

Interesting. I would have expected that to pop up in dtbs_check, but
it does not for some reason. I will fix it for all usb2phy instances
in rk3588.

The above follows everything from [0], which does not specify an
order for the "standard/common  properties". For those this follows
the order of existing usb2phy nodes. Did I miss any other new
Documentation?

While reading the text below I think it's in need for a clarification that the property order for common and vendor category is alpha-numerical as is for nodes.
For Rockchip DT in this case "reset*" below "clock*", so that the person after you can add properties in a sort list.

Johan

.===

The following order of properties in device nodes is preferred:

    "compatible"

    "reg"

    "ranges"

    Standard/common properties (defined by common bindings, e.g. without vendor-prefixes)

    Vendor-specific properties

    "status" (if applicable)

    Child nodes, where each node is preceded with a blank line

The "status" property is by default "okay", thus it can be omitted.
