Subject: [PATCH v4 00/13] media: qcom: camss: Add sm8550 support

v4:
- Update dt-bindings based on comments - Krzysztof, bod, Vladimir
- Move common code into csid core and vfe core driver - bod
- Remove *_relaxed in the csid and vfe drivers - Krzysztof
- Reorganize patches in logical junks, make sure that new added
structures have users in current patch - Krzysztof
- Remove notify function  and add new functions in camss for buf done
and reg update - bod
- Remove custom code to get csid base - bod
- Remove ISR function in vfe780 driver since it is never fired - bod
- Move csid_top_base to camss structure since we only have one csid
top block, and just need to get base once for csid top
- Add Vladimir's RB
- Remove prerequisite-patch-id in the cover letter since the changes
have been merged
- Add dtsi patch link for reference - Krzysztof

- Link to v3: https://lore.kernel.org/all/20240709160656.31146-1-quic_depengs@quicinc.com/

v3:
- Rebased the change based on below change which will be merged firstly.
"Move camss version related defs in to resources"
Link: https://lore.kernel.org/all/20240522154659.510-1-quic_grosikop@quicinc.com/
- Rebased the change based on Bryan's csiphy optimization change and add
these changes into this series, so that the new csiphy-3ph driver don't
need to add duplicate code. This has got Bryan's permission to add his
patches into this series.
- Refactor some changes based on the comments to move the random code to
patches where they are used.
- Remove the vfe780 irq function since it isn't doing the actual work.
- Add dt-binding for sm8550 camss driver.
Link to V2: https://lore.kernel.org/all/20240320141136.26827-1-quic_depengs@quicinc.com/

v2:
- Update some commit messages
Link to V1: https://lore.kernel.org/all/20240320134227.16587-1-quic_depengs@quicinc.com/

v1:
SM8550 is a Qualcomm flagship SoC. This series adds support to
bring up the CSIPHY, CSID, VFE/RDI interfaces in SM8550.

SM8550 provides

- 3 x VFE, 3 RDI per VFE
- 2 x VFE Lite, 4 RDI per VFE
- 3 x CSID
- 2 x CSID Lite
- 8 x CSI PHY
