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 v10 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 v10 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. Note that the
binding now does not describe every register subregion and instead
the driver holds the corresponding offsets.

While at it also include support for PCS_MISC region which was left
out earlier.

I am pretty sure I acked it and there were no changes here... but since
you did not include it, then lets keep the clock order the same as
sc8280xp. ABI is anyway affected, right?

Yes, I forgot to include your Ack in this version :(
Ok, I will fix the clock order in v11.

> Ok, I will fix the clock order in v11.

I just noticed that the clock orders are actually the same as sc8280xp.
The only clock diff between sm6115 and sc8280xp is actually 'cfg_ahb' 
clock used by sm6115 instead of 'aux' used by sc8280xp.

So, the clock order for sc8280xp is:
+            - const: aux
+            - const: ref
+            - const: com_aux
+            - const: pipe

whereas the same for sm6115 is:
+            - const: cfg_ahb
+            - const: ref
+            - const: com_aux
+            - const: pipe


Or, am I missing something? If not, may be I can include your Ack to 
help get this applied :)

Bhupesh
