Subject: [PATCH v5 0/2] qcom: qcs8300: Add qcs8300 camss support
QCS8300 is a Qualcomm SoC. This series adds bindings and devicetree
and driver changes to bring up CSIPHY, TPG, CSID, VFE/RDI interfaces
in QCS8300.
QCS8300 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
- 3 x CSIPHY
Changes in v5:
- Added Fixes: tag - Bryan
- Removed empty lines between single properties - Vladimir
- Modified binding phy supply description - Vladimir
- Link to v4:
https://lore.kernel.org/all/8966ddaf-9c10-4626-a4cc-36efd3fc93e2@kernel.org
Changes in v4 compared to v3:
- Added supplies in bindings to enable camera sensor.
This change was earlier added as V3.1 of Binidings which was
reviewed by Krzysztof and Bryan. Link to this discussion:
https://lore.kernel.org/all/20250910104915.1444669-1-quic_vikramsa@quicinc.com/
- Droped the zero-prefix from the size field un DT patch - Konrad
- Link to v3:
https://lore.kernel.org/all/20250813053724.232494-1-quic_vikramsa@quicinc.com/
Changes in v3 compared to v2:
- Bindings and Device Tree: Reordered csid_wrapper to appear first in the
register list (as suggested by Bryan).
- CSIPHY Driver: Updated the commit message for the CSIPHY patch.
- VFE/CSID Resource Data: Reused the same resource data as sa8775p for VFE
and CSID.
- Patch Series Order: Rearranged the patch sequence and moved the DTSI
update to the final patch in the series.
- Code Cleanup: Removed duplicate data structures and reused existing
ones.
- Optimization: Simplified and optimized conditional checks.
- Link to v2:
https://lore.kernel.org/linux-arm-msm/20250711131134.215382-1-quic_vikramsa@quicinc.com/
Changes compared to v1:
- Changed the order for register entries in bindings - Krzysztof
- Changed the naming for interrupts for consistency - Krzysztof
- Combined separate series for driver and dtsi into one.
- Rebased on top of latest version of sa8775p camss patches.
- Link to v1:
Driver: https://lore.kernel.org/all/20250214095611.2498950-1-quic_vikramsa@quicinc.com
DTSI: https://lore.kernel.org/all/20250214094747.2483058-1-quic_vikramsa@quicinc.com
We have tested this on qcs8300-ride board with 'Test Pattern Generator'
https://lore.kernel.org/all/20250925-camss_tpg-v4-0-d2eb099902c8@oss.qualcomm.com/
Used following tools for the sanity check of these changes.
