[PATCH v2 0/2] clk: qcom: rpmh: Add QCS9100 rpmh compatible

[PATCH v2 0/2] clk: qcom: rpmh: Add QCS9100 rpmh compatible

[Tengfei Fan]

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:

[PATCH v2 1/2] dt-bindings: clock: qcom-rpmhcc: Add RPMHCC bindings for QCS9100

[Tengfei Fan]

Add bindings and update documentation for clock rpmh driver on 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-rpmh-clk" to describe
non-SCMI based rpmhcc.

[PATCH v2 2/2] clk: qcom: rpmh: Add support for QCS9100 rpmh clocks

[Tengfei Fan]

Adds the RPMH clocks present in 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-rpmh-clk" to the rpmh clock
device match table.

After considering the feedback provided on the subject, We have decided
to keep current SA8775p compatible and ABI compatibility in drivers.
Let's close this session and ignore all the current patches here.
Thank you for your input.
