Subject: [PATCH 0/3] media: qcom: camss: Add qcs615 support

QCS615 is a Qualcomm flagship SoC. This series adds support to
bring up the CSIPHY, CSID, VFE/RDI interfaces in QCS615.

QCS615 provides

- 2 x VFE, 3 RDI per VFE
- 1 x VFE Lite, 4 RDI per VFE
- 2 x CSID
- 1 x CSID Lite
- 3 x CSI PHY

Tested this on QCS615 ADP AIR board with CSID TPG.

Tested with following commands:
media-ctl --reset
v4l2-ctl -d /dev/v4l-subdev3 -c test_pattern=0
media-ctl -V '"msm_csid0":0[fmt:SRGGB10/1920x1080 field:none]'
media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/1920x1080 field:none]'
media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
v4l2-ctl -d /dev/v4l-subdev3 -c test_pattern=9
yavta -B capture-mplane -n 5 -f SRGGB10P -s 1920x1080 /dev/video0 --capture=7
