Pull phy updates from Vinod Koul:
"This contains bunch of new device support and one new Sunplus driver
along with updates which include another big round of qmp phy
conversion.
New support:
- Qualcomm SC8280XP eDP & DP and USB3 UNI phy (Bjorn Andersson)
- Rockchip rk3568 inno dsidphy (Chris Morgan)
- ocelot-serdes phy yaml binding (Colin Foster)
- Renesas gen2-usb phy yaml binding (Geert Uytterhoeven)
- RGMII suport in lan966x driver (Horatiu Vultur)
- Qualcomm SM6375 usb snps-femto-v2 bindings (Konrad Dybcio)
- Rockchip rk356x csi-dphya (Michael Riesch)
- Qualcomm sdm670 usb2 bindings (Richard Acayan)
- Sunplus USB2 PHY (Vincent Shih)
Updates:
- Mediatek hdmi, ufs, tphy and xsphy updates to use bitfield helpers
(Chunfeng Yun)
- Continued Qualcomm qmp phy driver split and cleanup. More patches
are under review and expected that next cycle might see completion
of this activity (Dmitry Baryshkov & Johan Hovold)
- TI wiz driver support for j7200 10g (Roger Quadros)
- Qualcomm femto phy driver support for override params to help with
tuning (Sandeep Maheswaram)
- SGMII support in TI wiz driver (Siddharth Vadapalli)
- dev_err_probe simplification (Yuan Can)"
