It never happened before. > I need to check my mail client. Sorry for the noise. I don't see it, but I did not check each patch thoroughly. I also do not know to which patch do you refer to. It is the easiest to reply inline under the block which is corrupted. If you suspect you email client is the cause, just check on lore. Best regards, Krzysztof
Currently the DWC3 driver supports only single port controller which requires at most two PHYs ie HS and SS PHYs. There are SoCs that has DWC3 controller with multiple ports that can operate in host mode. Some of the port supports both SS+HS and other port supports only HS mode. This change primarily refactors the Phy logic in core driver to allow multiport support with Generic Phy's. Chananges have been tested on QCOM SoC SA8295P which has 4 ports (2 are HS+SS capable and 2 are HS only capable). Changes in v6: Updated comments in code after. Updated variables names appropriately as per review comments. Updated commit text in patch-2 and added additional info as per review comments. The patch header in v5 doesn't have "PATHCH v5" notation present. Corrected it in this version. Changes in v5: Added DT support for first port of Teritiary USB controller on SA8540-Ride Added support for reading port info from XHCI Extended Params registers. Changes in RFC v4: Added DT support for SA8295p. Changes in RFC v3: Incase any PHY init fails, then clear/exit the PHYs that are already initialized. Changes in RFC v2: Changed dwc3_count_phys to return the number of PHY Phandles in the node. This will be used now in dwc3_extract_num_phys to increment num_usb2_phy and num_usb3_phy. Added new parameter "ss_idx" in dwc3_core_get_phy_ny_node and changed its structure such that the first half is for HS-PHY and second half is for SS-PHY. In dwc3_core_get_phy, for multiport controller, only if SS-PHY phandle is present, pass proper SS_IDX else pass -1.
