Add support for the RDI only CAMSS camera driver on SM8750. Enabling
RDI path involves adding the support for a set of CSIPHY, CSID and TFE
modules, with each TFE having multiple RDI ports. This hardware
architecture requires 'qdss_debug_xo' clock for CAMNOC to be functional.
SM8750 camera subsystem provides:
- 6 x CSIPHY (CSI Physical Layer)
- 3 x TPG (Test Pattern Generator)
- 3 x CSID (CSI Decoder)
- 2 x CSID Lite
- 3 x VFE (Video Front End), 5 RDI per VFE
- 2 x VFE Lite, 4 RDI per VFE Lite
This series has been tested using the following commands with a
downstream driver for S5KJN5 sensor.
- media-ctl --reset
- media-ctl -V '"msm_csiphy2":0[fmt:SGBRG10/4096x3072]'
- media-ctl -V '"msm_csid0":0[fmt:SGBRG10/4096x3072]'
- media-ctl -V '"msm_vfe0_rdi0":0[fmt:SGBRG10/4096x3072]'
- media-ctl -l '"msm_csiphy2":1->"msm_csid0":0[1]'
- media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
- yavta --capture=20 -I -n 5 -f SGBRG10P -s 4096x3072 -F /dev/video0

Changes in v4:
- Update dependency to kaanapali camss v14 and rebase to resolve conflict
- Link to v3: https://lore.kernel.org/r/20260508-add-support-for-camss-...
Changes in v3:
- Revert binding from full hardware description to CAMSS-only scope for
modular and incremental development - bod
- Rename icc path names and vfe clock names to drop redundancies - Krzysztof
- Separate port index from VC value in csid_configure_stream(). Previously
vc was used as both the loop iterator and the hardware VC, causing
misconfiguration on RDI path starting from 1 - bod
- Link to v2: https://lore.kernel.org/all/20260119-add-support-for-cams...
Changes in v2:
- Rebase this series due to conflict - bod
- Add module descriptions in binding commit message and cover letter
- Update property names to align with previous generations - Krzysztof
- Update the vdd supply names with 0p88 to 0p9 in binding to keep such name
style consistency - Krzysztof/Vladimir
- Add missing Kaanapali dependency - Krzysztof
- Add regulator current in csiphy resource due to interface changed - bod
- Make csid board level code style consistent and add comments to explain
the differences between csid full and lite configurations - bod
- Remove redundant initialization for empty set in csid and vfe - bod
- Remove DTS patch due to conflict with camcc dependency. Will post it
as an individual series.
- Update vfe commit message as renaming work done in Kaanapali series
- Revert change-id to v1 to avoid increasing reviewers' workload
- Link to v1: https://lore.kernel.org/r/20251126-add-support-for-camss-...
