Subject: [PATCH v4 0/9] Add sa8775p camss support
From: Vikram Sharma <vikramsa@....qualcomm.com>
SA8775P is a Qualcomm SoC. This series adds bindings and devicetree to bring
up CSIPHY, TPG, CSID, VFE/RDI interfaces in SA8775P.
SA8775P provides
- 2 x VFE, 3 RDI per VFE
- 5 x VFE Lite, 6 RDI per VFE
- 2 x CSID
- 5 x CSID Lite
- 3 x TPG
- 4 x CSIPHY
Changes in v4 compared to v3:
- Bindings and Device Tree: Reordered the csid_wrapper to be the first
entry in the register list. (Suggested by Bryan)
- CSIPHY Driver: Added comments indicating the CSIPHY process node number.
- VFE Configuration: Defined bit fields for vfe_top_core_cfg.
- Clock Optimization: Trimmed down the clock list for VFE.
- Cleanup: Removed newly added deadlines from the CSIPHY, CSID, and VFE
files.
- Link to v3:
https://lore.kernel.org/all/20250703171938.3606998-1-quic_vikramsa@quicinc.com/
Changes compared to v2:
- Renaming camss-vfe-780.c to camss-vfe-gen3.c and camss-csid-780 to
camss-csid-gen3 to avoid code duplication for SA8775P.SA877P have csid
690 and vfe 690 which is almost same as csid/vfe 780 with very minor
change in register bitfield.
- Restructure vfe and csid addition to reuse existing files.
- Updated commit text for Bindings patch.
- renamed cpas_ife_lite clock to cpas_vfe_lite.
- added voltage rails for csiphy in documentation.
- removed sf and icp clocks.
- removed sf_0 interconnect.
- Link to v2:
https://lore.kernel.org/linux-arm-msm/20250427070135.884623-1-quic_vikramsa@quicinc.com/
Changes compared to v1:
- Renaming camss-vfe-780.c to camss-vfe-gen2.c and camss-csid-780 to
camss-csid-gen3 to avoid code duplication for SA8775P.SA877P have csid
690 and vfe 690 which is almost same as csid/vfe 780 with very minor
change in register bitfield.
- Restructure vfe and csid addition to reuse existing files.
- Updated cisd-lite and vfe-lite interuppt names.
- add enumeration changes as seprate patch.
- Update required fileds in bindings.
- Link to v1:
DT: https://lore.kernel.org/linux-arm-msm/20250210155605.575367-1-quic_vikramsa@quicinc.com/

Sanity check for these patches:
- make CHECK_DTBS=y W=1 DT_SCHEMA_FILES=media/qcom,sa8775p-camss.yaml
- make DT_CHECKER_FLAGS=-m W=1
DT_SCHEMA_FILES=media/qcom,sa8775p-camss.yaml dt_binding_check
- checkpatch.pl
- Smatch: make CHECK="smatch --full-path" M=drivers/media/platform/qcom/camss/
- make -j32 W=1
We have tested this on qcs9100-ride board with 'Test Pattern Generator'
https://lore.kernel.org/all/20250717-lemans_tpg-v2-0-a2538659349c@quicinc.com/
A rebased version of the TPG driver, built on top of this series, will be
shared as v3 in a follow-up post.
