[PATCH v6 00/16] 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, and adds fix-ups for the QCM2290 Clock
drivers.

Changes in v6:
- Rebased on next-20260716, as the dependent RPMCC/GCC and Shikra base DTS
  changes were merged.
- Collected all Reviewed-by tags received on v5.
- Added the Fixes tags to relevant patches [Dmitry/Konrad]
- Reordered the series to place the fix patches at top of the series [Dmitry]
- Updated the DISPCC driver to use use_rpm, as required by the
  power-domain fix-up changes [Konrad]
- Dropped the additional external clock, index-based driver, and DTS
  changes to avoid an ABI change that has no functional impact [Krzysztof/Konrad]
- Updated the commit text for few patches [Konard/Dmitry]
- Link to v5: https://lore.kernel.org/r/20260703-shikra-dispcc-gpucc-v5-0-cc13826d4d5a@xxxxxxxxxxxxxxxx

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.
- Dropped moving dispcc driver to DT index approach patch as the
  external sleep_clk is not there in the DTS, and no functional impact.
- Dropped HW_CTRL_TRIGGER patch as it is not applicable [Konrad]
- 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 common qcom_cc_probe() model
  and reuse for Shikra.
