The pins and functions in these device tree nodes are not changeable, a board file should just select proper pairs.

Since I'm able to reproduce it, I'll take the analysis on myself, and it does not interfere with your patch series. -- Best wishes, Vladimir

Ah, I think I have it pretty much narrowed down now. Needed to switch off modules entirely. First probe fails, second probe succeeds. Thanks anyway, I think I'm close to fix. --- bod

The IMX577 is on CCI1/CSI2 providing four lanes of camera data. An example media-ctl pipeline is: media-ctl --reset media-ctl -v -d /dev/media0 -V '"imx412 '20-001a'":0[fmt:SRGGB10/4056x3040 field:none]' media-ctl -V '"msm_csiphy2":0[fmt:SRGGB10/4056x3040]' media-ctl -V '"msm_csid0":0[fmt:SRGGB10/4056x3040]' media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4056x3040]' media-ctl -l '"msm_csiphy2":1->"msm_csid0":0[1]' media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]' yavta -B capture-mplane -c -I -n 5 -f SRGGB10P -s 4056x3040 -F /dev/video0 Signed-off-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org> --- arch/arm64/boot/dts/qcom/qrb5165-rb5.dts | 98 ++++++++++++++++++++++++ 1 file changed, 98 insertions(+)
