This patchset adds the support for USB SS qmp phy for Qualcomm SM6115
SoC. For the previous versions of this patch there were conversations
on irc as to whether this was a 'qcom,usb-ssphy-qmp-usb3-or-dp' or a
'qcom,usb-ssphy-qmp-dp-combo' as per downstream code and hardware
documentation.

But after a careful look at downstream dtsi (see [1]) it appears that
this indeed is a 'qcom,usb-ssphy-qmp-usb3-or-dp' phy and not a
'dp-combo' phy.

[PATCH v9 1/4] dt-bindings: phy: qcom,qmp-usb: Drop legacy bindings and move to newer one (SM6115 & QCM2290)

[Bhupesh Sharma]

'qcom,msm8996-qmp-usb3-phy.yaml' defines bindings for several PHYs
which predate USB -> USB+DP migration. Since SM6115 and QCM2290
nodes for USB QMP phy are being added to dtsi files by followup patches,
move these bindings instead to the newer style
'qcom,sc8280xp-qmp-usb3-uni-phy.yaml' file.

Since no device trees use these bindings presently, so we have no ABI breakages
with this patch.

[PATCH v9 2/4] phy: qcom-qmp-usb: add support for updated qcm2290 / sm6115 binding

[Bhupesh Sharma]

Add support for the new qcm2290 / sm6115 binding.

The USB QMP phy on these devices supports 2 lanes. Also note that the
binding now does not describe every register subregion and instead
the driver holds the corresponding offsets. This also includes
the PCS_MISC region.

pcs_misc should also be usable for a single-lane PHYs.

I replied with R-B, but then I noticed that the length of the region is
