Subject: [PATCH v6 0/5] media: qcom: camss: Add sc7280 support

SC7280 is a Qualcomm SoC. This series adds support to bring up the CSIPHY,
CSID, VFE/RDI interfaces in SC7280.

SC7280 provides

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

The changes are verified on SC7280 qcs6490-rb3gen2 board, with attached vision mezzanine
the base dts for qcs6490-rb3gen2 is:
