This series adds support for camera clock controller base driver, bindings and DT support on sc8180x platform.
Signed-off-by: Satya Priya Kakitapalli quic_skakitap@quicinc.com --- Changes in v3: - Drop Fixes tag in patch [1/4]. Dropped unused gpu_iref and aggre_ufs_card_2 clk bindings. - Move the allOf block below required block in bindings patch. - Remove the unused cam_cc_parent_data_7 and cam_cc_parent_map_7 in the driver patch. Reported by kernel test bot. - Link to v2: https://lore.kernel.org/r/20250430-sc8180x-camcc-support-v2-0-6bbb514f467c@q...
Changes in v2: - New patch [1/4] to add all the missing gcc bindings along with the required GCC_CAMERA_AHB_CLOCK - As per Konrad's comments, add the camera AHB clock dependency in the DT and yaml bindings. - As per Vladimir's comments, update the Kconfig to add the SC8180X config in correct alphanumerical order. - Link to v1: https://lore.kernel.org/r/20250422-sc8180x-camcc-support-v1-0-691614d13f06@q...

Best regards,
The multi-media AHB clocks are needed to create HW dependency in the multimedia CC dt blocks and avoid any issues. They were not defined in the initial bindings. Add all the missing clock bindings for gcc-sc8180x.

Drop, we already asked for this: you are not fixing any bug.
Read carefully stable kernel rules.
