Good Morning,

This is my patch series that I have maintained out of tree until the
combophy driver landed.

Patch 1 fixes the grf dt binding from the combophy merge.
Patch 2 adds the dt bindings for the grf changes necessary.
Patch 3 adds support to the grf driver to set the rk3566 otg clock
source.
Patch 4 is a downstream patch ported forward to shut down the usb3 clock
when the controller is operating in usb2 mode.
Patch 5 adds the dwc3 nodes to the rk356x device tree includes.
Patch 6 enables the dwc3 nodes on the Quartz64 Model A.
Patch 7 enables the dwc3 nodes on the rk3568-evb.

Note, there are functional changes from previous versions.

Please review and apply.

Very Respectfully,
Peter Geis

Changelog:
v3:
- Drop the dwc-of-simple method in favor of using dwc core.
- Drop all quirks except snps,dis_u2_susphy_quirk, which is necessary to
  prevent device detection failures in some states.
- Drop the reset-names.

v2:
- Add a dt-bindings fix for grf.yaml
- Unify the reset names.
- Constrain the force usb2 clock dwc3 patch to only supported variants of
the ip.
- Change dwc3-of-simple to support of-match-data.
- Drop the PCLK-PIPE clk.
- Rename the usb nodes to be more friendly.
- Add the rk3568-evb enable patch.

compatible = "rockchip,rk3568-dwc3", "snps,dwc3";

compatible strings must be SoC orientated.
Add binding like you did before.

Okay, should this go in the core yaml, since it's not really handled
by of-simple?
Also, should I add in the compatible for rk3328 as well?

I wonder what the correct place for this extcon property is. You defined
it on SoC (RK3566) level, in my patch for the RK3568 EVB1 it is added on
board level. Is this common to all RK356x variants?

Best regards,
Michael

Nothing to change in core.c, because the fall back string does the
trick, so we don't have to change the driver for every new SoC.
Change the node compatible here and add the binding.
That's it. The rest comes later if needed.

> Also, should I add in the compatible for rk3328 as well?

No, same story the fall back string does the trick in core.c

Yes, the usb2phy is always available as an extcon unless you make a
device that doesn't have usb2 capability.
In that case you'd have to override the device anyways.
If we want to turn on default role otg here, we'd need this defined
here as well or things break.

It's the binding I'm referring to here.
snps,dwc3.yaml seems the logical place, but I want to make sure you
concur first.

Same thing here, since I'm in snps,dwc3.yaml anyways I can add the
rk3328 binding in and silence that error in one go.

rockchip,dwc3.yaml is the place be!
Hurry up!

Use Michael's patch, because his commit message is better.(no reference
to rk3399)

It's been done already:

OK, so it seems to me that the extcon could or should enter the
rk356x.dtsi (and can be removed from the rk3566.dtsi and the
rk3568-evb1-v10.dts in this series). Is that correct?

Best regards,
Michael

Apologies it seems I just missed this.
Yes, this could get moved to the base dtsi.
I'd prefer to do it as part of the next series supporting otg, as I've
only been doing OTG development on the rk3566 and would prefer it be
fully tested.
However if Johan prefers I can send another revision accomplishing this now.
