[PATCH v2 0/2] soc: qcom: llcc: Add QCS9100 LLCC 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: cache: qcom,llcc: Add QCS9100 description

[Tengfei Fan]

Add the cache controller compatible and register region descriptions for
QCS9100 platform.
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-llcc" to describe non-SCMI
based LLCC.

Add llcc configuration support for the QCS9100 platform.
QCS9100 is drived from SA8775p. Currently, both the QCS9100 and SA8775p
platform use non-SCMI resource. In the future, the SA8775p platform will

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.
