Add driver for Eliza SoC camera, graphics and Video clock controllers.
The camera clock controller supports the cambist clock controller and
the regular camera clock controller.
Eliza camcc and videocc are on CX and MX rails and doesn't have MMCX
and MXC rails dependency. Add explicit power-domain voting for Milos
which are required. Hence extended the Milos camcc & videocc
documentation bindings for Eliza.
The patches have been tested on Qualcomm Eliza MTP board.
Changes in v7:
- Add missing 'power-domains' and 'required-opps' properties to the
Milos camcc and videocc dt-bindings, and the corresponding device
tree nodes, since the Eliza bindings extend the Milos ones. [Konrad]
- Update the camcc, videocc driver to 'use_rpm' flag for Eliza.
- Add the RB-by tags from patchset v6.
- Link to v6: https://lore.kernel.org/r/20260609-b4-eliza_mm_cc_v6-v6-0-17df09e5940c@oss.qualcomm.com
Changes in v6:
- Update device tree to latest linux-next.
- Update commit text for no ABI breakage for VideoCC and CAMCC
binding [Krzysztof]
- Added the RB-by from patchset v5.
- Link to v5: https://lore.kernel.org/r/20260525-eliza_mm_cc_v2-v5-0-a1d125619a5a@oss.qualcomm.com
Changes in v5:
- Taken care of comments from v3, v4.
- Update milos-videocc and milos-camcc bindings to add '#power-domain-cells'
as required property in bindings.
- Remove duplicate clock 'gpu_cc_gpu_smmu_vote_clk' from driver and
bindings.
- Add '#power-domain-cells' for 'camcc' and 'cambistmclkcc' device node.
- Link to v4: https://lore.kernel.org/r/20260513-eliza_mm_cc_v2-v4-0-e61b5434e8d9@oss.qualcomm.com
Changes in v4:
- Update the clock ordering for camcc and cambistmclkcc in milos.dtsi.
- Link to v3: https://lore.kernel.org/r/20260513-eliza_mm_cc_v2-v3-0-b59c370dc281@oss.qualcomm.com
Changes in v3:
- Dropped new documentation bindings & extended Milos documentation bindings for Eliza videocc & camcc.
- Dropped the defconfig patch and included the drivers as m from Kconfig itself.
- Update the header inclusion in the milos.dtsi.
- Link to v2: https://lore.kernel.org/r/20260409-eliza_mm_cc_v2-v2-0-bc0c6dd77bc5@oss.qualcomm.com
Changes in v2:
- rebased the patches on the latest linux-next.
- Add new bindings for Video and Camcc.
- Remove commented code in GPUCC (limiter code).
- Add device nodes for the corresponding clock controllers.
- Add RB-by tags for VideoCC and CamCC/Cambistmclk from v1.
