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.
