[PATCH v4 0/8] enable usb support on rk356x

[Peter Geis]

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 the SoC specific binding.
Patch 4 adds support to the grf driver to set the rk3566 otg clock
source.
Patch 5 is a downstream patch ported forward to shut down the usb3 clock
when the controller is operating in usb2 mode.
Patch 6 adds the dwc3 nodes to the rk356x device tree includes.
Patch 7 enables the dwc3 nodes on the Quartz64 Model A.
Patch 8 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:
v4:
- Add SoC specific binding, fall back to core.
 
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.
