Subject: [PATCH v2] dt-bindings: phy: qcom,usb-snps-femto-v2: Add bindings
 for QCS9100

Document the compatible string for USB phy found in Qualcomm QCS9100
SoC.
QCS9100 is drived from SA8775p. Currently, both the QCS9100 and SA8775p
platform use non-SCMI resource. In the future, the SA8775p platform will
move to use SCMI resources and it will have new sa8775p-related device
tree. Consequently, introduce "qcom,qcs9100-usb-hs-phy" to describe
non-SCMI based USB phy.

Introduce support for the QCS9100 SoC device tree (DTSI) and the
QCS9100 RIDE board DTS. The QCS9100 is a variant of the SA8775p.
While the QCS9100 platform is still in the early design stage, the
QCS9100 RIDE board is identical to the SA8775p RIDE board, except it
mounts the QCS9100 SoC instead of the SA8775p SoC.

The QCS9100 SoC DTSI is directly renamed from the SA8775p SoC DTSI, and
all the compatible strings will be updated from "SA8775p" to "QCS9100".
The QCS9100 device tree patches will be pushed after all the device tree
bindings and device driver patches are reviewed.

The final dtsi will like:
