[PATCH v3 0/7] qcom: qcs8300: Add qcs8300 camss support

[Vikram Sharma]

From: Vikram Sharma <vikramsa@xxxxxxxxxxxxxxxx>

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 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@xxxxxxxxxxx/

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@xxxxxxxxxxx
  DTSI: https://lore.kernel.org/all/20250214094747.2483058-1-quic_vikramsa@xxxxxxxxxxx  

Dependencies:

We have tested this on qcs8300-ride board with 'Test Pattern Generator'
https://lore.kernel.org/all/20250717-qcs8300_tpg-v2-1-0946c69c2c8b@xxxxxxxxxxx/

A rebased version of the TPG driver, built on top of this series, will be
shared in a follow-up post.

Used following tools for the sanity check of these changes.
