All currently known QMP UFS PHYs have the same offsets for register sub-regions. Instead of using qmp_ufs_offsets_v5 for older generations of PHYs, rename the offsets struct instance to remove _v5 suffix. Signed-off-by:

The WIZ acts as a wrapper for SerDes and has Lanes 0 and 2 reserved for USB for type-C lane swap if Lane 1 and Lane 3 are linked to the USB PHY that is integrated into the SerDes IP. The WIZ control register has to be configured to support this lane swap feature. The support for swapping lanes 2 and 3 is missing and therefore add support to configure the control register to swap between lanes 2 and 3 if PHY type is USB. Signed-off-by:

It's possible that the Type-C plug orientation on the DIR line will be implemented through hardware design. In that situation, there won't be an external GPIO line available, but the driver still needs to address this since the DT won't use the typec-dir-gpios property. Add code to handle LN10 Type-C swap if typec-dir-gpios property is not specified in DT. Signed-off-by:

UFS PHY in SC8280XP SoC is capable of operating at HS G4 mode and the init sequence is compatible with SM8350. Hence, add the tbls_hs_g4 instance reusing the G4 init sequence of SM8350. Reviewed-by:

SM8350 default init sequence sets some PCS registers to HS G3, thereby disabling HS G4 mode. This has the effect on MPHY capability negotiation between the host and the device during link startup and causes the PA_MAXHSGEAR to G3 irrespective of device max gear. Due to that, the agreed gear speed determined by the UFS core will become G3 only and the platform won't run at G4. So, let's remove setting these registers for SM8350 as like other G4 compatible platforms. One downside of this is that, when the board design uses non-G4 compatible device, then MPHY will continue to run in the default mode (G4) even if UFSHCD runs in G3. But this is the case for other platforms as well. Tested-by: Andrew Halaney <ahalaney@redhat.com> # Qdrive3/sa8540p-ride Signed-off-by:

Since now there is support for configuring the HS Rate B mode properly, let's move the register setting to tbls_hs_b struct for all SoCs. This allows the PHY to be configured in Rate A initially and then in Rate B if requested by the UFS driver. Reviewed-by:

Add separate tables_hs_g4 instance to allow the PHY driver to configure the PHY in HS G4 mode. The individual SoC configs need to supply the Rx, Tx and PCS register setting in tables_hs_g4 and the UFS driver can request the Hs G4 mode by calling phy_set_mode_ext() with submode set to UFS_HS_G4.

As done for Qcom PCIe PHY driver, let's move the register settings to the common qmp_phy_cfg_tbls struct. This helps in adding any additional PHY settings needed for functionalities like HS-G4 in the future by adding one more instance of the qmp_phy_cfg_tbls. Reviewed-by:

Document SoC-specific compatibles with generic fallback (e.g. qcom,usb-snps-hs-7nm-phy) already used in DTSI. Add SoC-specific compatibles for PHY on SDX55 and SDX65.

Do not touch remaining two compatibles - qcom,usb-snps-femto-v2-phy and qcom,sc8180x-usb-hs-phy - because there are no upstream users, so not sure what was the intention for them.

Add r8a779f0_eth_serdes_power_on() to initialize the hardware for each channel from the step 9 or later on the datasheet. In other words, the procedure from the step 1 to 8 is for all channel and it is needed once only. So, the .init() in any channel instance is called, this driver initializes the hardware from step 1 to 8. And then, .power_on() is called, this driver initializes the hardware from step 9 or later.

So far we were assigning some crude "type" (SoC name, really) to each Allwinner USB PHY model, then guarding certain quirks based on this. This does not only look weird, but gets more or more cumbersome to maintain. Remove the bogus type names altogether, instead introduce flags for each quirk, and explicitly check for them. This improves readability, and simplifies future extensions. Signed-off-by:
