[PATCH v4 0/2] qcom: qcs8300: Add qcs8300 camss support

[Vikram Sharma]

From: Vikram Sharma <vikramsa at qti.qualcomm.com>

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 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:

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/
