Currently the DWC3 driver supports only single port controller
which requires at most one HS and one SS PHY.

But the DWC3 USB controller can be connected to multiple ports and
each port can have their own PHYs. Each port of the multiport
controller can either be HS+SS capable or HS only capable
Proper quantification of them is required to modify GUSB2PHYCFG
and GUSB3PIPECTL registers appropriately.

Add support for detecting, obtaining and configuring phy's supported
by a multiport controller and limit the max number of ports
supported to 4.

Note that this patch no longer applies and you need to rebase the series
on mainline (e.g. including commit 1d72fab47656 ("USB: dwc3: refactor
phy handling").

Hi Johan,

This series is rebased on top of usb-next (on top of the above mentioned patch). Probably that is why its not applying on top of linux-next.

Krishna,
