Subject: [PATCH v2 0/7] qcom: qcs8300: Add qcs8300 camss support

From: Vikram Sharma <vikramsa@....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 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  

Dependencies:
https://lore.kernel.org/all/20250703171938.3606998-1-quic_vikramsa@quicinc.com

Driver side changes for TPG will be submitted as a separate series which will be
rebased on top of these patches.

Tested with following commands:
- media-ctl -d /dev/media0 --reset
- yavta --no-query -w '0x009f0903 0' /dev/v4l-subdev0
- media-ctl -d /dev/media0 -V '"msm_tpg0":0[fmt:SRGGB10/1920x1080
  field:none]'
- media-ctl -d /dev/media0 -V '"msm_csid0":0[fmt:SRGGB10/1920x1080
  field:none]'
- media-ctl -d /dev/media0 -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/1920x1080
  field:none]'
- media-ctl -d /dev/media0 -l '"msm_tpg0":1->"msm_csid0":0[1]'
- media-ctl -d /dev/media0 -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
- yavta --no-query -w '0x009f0903 9' /dev/v4l-subdev0
- yavta -B capture-mplane -n 5 -f SRGGB10P -s 1920x1080 /dev/video0
