2022-08-30phy: qcom-qmp: Add SC8280XP USB3 UNI phyBjorn Andersson
The SC8280XP platform has two instances of the 5nm USB3 UNI phy attached to the multi-port USB controller, add definition for these.

Other PHYs tables directly reference QPHY_PLL_LOCK_CHK_DLY_TIME register without using reglayout. Define corresponding register to be used by msm8996 PHY tables and use it directly.

2022-07-07phy: qcom-qmp: split PCS_UFS V3 symbols to separate headerDmitry Baryshkov
Several registers defined in the PCS V3 namespace in reality belong to the PCS_UFS V3 register space. Move them to the separate header and rename them to explicitly mention PCS_UFS. While we are at it, correct one register in the msm8998_usb3_pcs_tbl table to use PCS register name.

2022-07-07phy: qcom-qmp-combo,usb: add support for separate PCS_USB regionDmitry Baryshkov
Different QMP USB PHYs might have different offset from PCS to PCS_USB register space, but the same PCS_USB register layout. Add separate PCS_USB region space and merge related PCS_USB definitions.

2022-07-05phy: qcom-qmp-usb: clean up pipe clock handlingJohan Hovold
Clean up the pipe clock handling by using dev_err_probe() to handle probe deferral and dropping the obsolete comment that claimed that the pipe clock was optional for some other PHY types.
