Monaco EVK board does not include a camera sensor in its default hardware
configuration. Introducing a device tree overlay to support optional
integration of the IMX577 sensor via CSIPHY1.
Camera reset is handled through an I2C expander, and power is enabled
via TLMM GPIO74.
An example media-ctl pipeline for the imx577 is:
media-ctl --reset
media-ctl -V '"imx577 3-001a":0[fmt:SRGGB10/4056x3040 field:none]'
media-ctl -V '"msm_csiphy1":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_csiphy1":1->"msm_csid0":0[1]'
media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'

Please remove 'clock-lanes' property here.

data-lanes property value should be '1 2 3 4>', 0 is for the clock lane.
On CAMSS side this cannot be changed, unfortunately it's a lingering issue.

If only one of 3 defined from 4/5 regulators is used, do you really wish
to describle all 3 in advance? You may consider to remove 2 currently unused
GPIO controlled regulator descriptions, and squash this change with 4/5.

So, I should set data-lanes = <1 2 3 4> in imx577_ep1, and keep csiphy1_ep as <0 1 2 3>, correct?
Is there a reason CAMSS side can’t change this? We should handle it properly in future targets.

As discussed, we agreed to add support for other sensors: https://lore.kernel.org/all/4b73f64a-1e28-4f25-80d2-3d59575b9da2@oss.qualcomm.com
Regulator changes are in monaco-evk.dts, and sensor overlay changes are present in monaco-evk-camera-imx577.dtso
It’s better to keep these as separate patches rather than merging them into one.
