Subject: [PATCH v8 0/5] media: qcom: camss: Add sc7280 support
SC7280 is a Qualcomm SoC. This series adds support to bring up the CSIPHY,
CSID, VFE/RDI interfaces in SC7280.
SC7280 provides
- 3 x VFE, 3 RDI per VFE
- 2 x VFE Lite, 4 RDI per VFE
- 3 x CSID
- 2 x CSID Lite
- 5 x CSI PHY
We have tested this on qcs6490-rb3gen2-vision-mezzanine board having IMX577
sensor. Verified both TPG and IMX577 sensor.
Used following tools for the sanity check of these changes.
- make CHECK_DTBS=y W=1 DT_SCHEMA_FILES=media/qcom,sc7280-camss.yaml
qcom/qcs6490-rb3gen2-vision-mezzanine.dtb
- make DT_CHECKER_FLAGS=-m W=1
DT_SCHEMA_FILES=media/qcom,sc7280-camss.yaml dt_binding_check
- Smatch: make CHECK="smatch --full-path"
M=drivers/media/platform/qcom/camss/
- Sparse: make C=2 M=drivers/media/platform/qcom/camss/
- coccicheck : make coccicheck M=drivers/media/platform/qcom/camss/
- make -j32 W=1
- ./scripts/checkpatch.pl
Changes in V8:
- Changed node name from camss to isp.
- Added QCOM_ICC_TAG_ACTIVE_ONLY and QCOM_ICC_TAG_ALWAYS tags for
interconnects.
- Added blank lines when required.
- Modified power-domain-names from horizontal to vertical list.
- Sorted pinctrl nodes based on gpio index.
- Link to v7: https://lore.kernel.org/linux-arm-msm/20241204100003.300123-1-quic_vikramsa@quicinc.com/
Changes in V7:
- Changed unit address for camss in documention and dts.
- Added avdd-supply and dvdd-supply for sensor.
- Changed reg/clocks/interrupts name for vfe_lite and csid_lite.
- Link to v6: https://lore.kernel.org/linux-arm-msm/20241127100421.3447601-1-quic_vikramsa@quicinc.com/
Changes in V6:

- Renamed power-domains-names -> power-domain-names.
- Link to v4: https://lore.kernel.org/linux-arm-msm/20241030105347.2117034-1-quic_vikramsa@quicinc.com/
Changes in V4:
- V3 had 8 patches and V4 is reduced to 6.
- Removed [Patch v3 2/8] as binding change is not required for dtso.
- Removed [Patch v3 3/8] as the fix is already taken care in latest
kernel tip.
- Updated alignment for dtsi and dt-bindings.
- Adding qcs6490-rb3gen2-vision-mezzanine as overlay.
- Link to v3: https://lore.kernel.org/linux-arm-msm/20241011140932.1744124-1-quic_vikramsa@quicinc.com/
Changes in V3:
- Added missed subject line for cover letter of V2.
- Updated Alignment, indentation and properties order.

Changes in V2:
- Improved indentation/formatting.
- Removed _src clocks and misleading code comments.
- Added name fields for power domains and csid register offset in DTSI.
- Dropped minItems field from YAML file.
- Listed changes in alphabetical order.
- Updated description and commit text to reflect changes
- Changed the compatible string from imx412 to imx577.
- Added board-specific enablement changes in the newly created vision
board DTSI file.
- Fixed bug encountered during testing.
- Moved logically independent changes to a new/seprate patch.
- Removed cci0 as no sensor is on this port and MCLK2, which was a
copy-paste error from the RB5 board reference.
- Added power rails, referencing the RB5 board.
- Discarded Patch 5/6 completely (not required).
- Removed unused enums.
