[PATCH v5 00/19] clk: qcom: Add DISPCC and GPUCC support for the Qualcomm Shikra SoC

[Imran Shaik]

This series adds support for the Display clock controller (DISPCC) and
GPU Clock Controller (GPUCC) on Qualcomm Shikra SoC, by reusing the
respective QCM2290 SoC drivers.

This series extends the QCM2290 DISPCC bindings by adding support for the
DSI1 PHY and sleep clock inputs, as well as the CX power rail. The Agatti
device tree is updated accordingly to comply with the revised bindings.
As a result, the existing DISPCC binding and corresponding DT ABI are
changed, making this an ABI-breaking update.

Changes in v5:
- Collected all Reviewed-by tags received on v4.
- Updated the commit text of the bindings patches [Krzysztof]
- Converted only the critical GCC clocks to the latest clk_cbcr convention
- Reorganize the series into logically independent patches [Krzysztof/Dmitry]
- Added CX power domain support for DISPCC [Konrad]
- Dropped DSI1 PHY clock input support from the driver, as these clocks
  are not referenced by any frequency table.
- Link to v4: https://lore.kernel.org/r/20260604-shikra-dispcc-gpucc-v4-0-8204f1029311@xxxxxxxxxxxxxxxx

Changes in v4:
- Included new patch for Shikra DISPCC/GPUCC DT node support
- Link to v3: https://lore.kernel.org/r/20260601-shikra-dispcc-gpucc-v3-0-61c1ba3735e8@xxxxxxxxxxxxxxxx

Changes in v3:
- Updated the QCM2290 GCC patch to use the .clk_cbcr convention
- Extended the QCM2290 GPUCC bindings to add DSI1 PHY and Sleep clocks
- Separated the patches as per the review comments in v2 series
- Added Agatti DISPCC DT node changes as per the latest bindings changes
- Link to v2: https://lore.kernel.org/r/20260528-shikra-dispcc-gpucc-v2-0-953f246a0fbb@xxxxxxxxxxxxxxxx

Changes in v2:
- Dropped QCM2290 GCC critical clocks modelling to kept them ON from probe.
- Updated the QCM2290 DISPCC/GPUCC bindings to align for Shikra drivers reuse.
- Reused the QCM2290 DISPCC driver for Shikra without modernizing
  (keeping the clock-names approach) for now to avoid potential bindings ABI breakage.
- Modernized QCM2290 GPUCC driver to use commmon qcom_cc_probe() model
  and reuse for Shikra.
