Add support for the RDI only CAMSS camera driver on SM8750. Enabling
RDI path involves adding the support for a set of CSIPHY, CSID and TFE
modules, with each TFE having multiple RDI ports. This hardware
architecture requires 'qdss_debug_xo' clock for CAMNOC to be functional.
SM8750 camera subsystem provides
- 3 x VFE, 5 RDI per VFE
- 2 x VFE Lite, 4 RDI per VFE Lite
- 3 x CSID
- 2 x CSID Lite
- 6 x CSI PHY
- 2 x ICP
- 1 x IPE
- 2 x JPEG DMA & Downscaler
- 2 x JPEG Encoder
- 1 x OFE
- 5 x RT CDM
- 3 x TPG
This series has been tested using the following commands with a
downstream driver for S5KJN5 sensor.
- media-ctl --reset
- media-ctl -V '"msm_csiphy2":0[fmt:SGBRG10/4096x3072]'
- media-ctl -V '"msm_csid0":0[fmt:SGBRG10/4096x3072]'
- media-ctl -V '"msm_vfe0_rdi0":0[fmt:SGBRG10/4096x3072]'
- media-ctl -l '"msm_csiphy2":1->"msm_csid0":0[1]'
- media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'
- yavta --capture=20 -I -n 5 -f SGBRG10P -s 4096x3072 -F /dev/video0
