Currently the DWC3 driver supports only single port controller which

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.

Changes have been tested on QCOM SoC SA8295P which has 4 ports (2
are HS+SS capable and 2 are HS only capable).


I think I said it few times on the lists to Qualcomm folks, although I
cannot remember whether exactly in this patchset. Please split DTS from
USB, because Greg prefers to grab everything and DTS *should go* via
Qualcomm SoC.

Hi Krzyztof,

Apologies !

Do you mean to send the DTS just to linux-arm-msm list and not linux-usb list ? I don't think it was posted on this series and I am not on linux-arm-msm mailing list, so missed that comment. Sorry for that. I saw some series where DT, Driver and bindings were sent as one set to linux-usb list as well and so wanted to follow suite. Will make sure to send DT just to linux-arm-msm list from now on. Thanks for the comments :-)

Regards,
Krishna,
