Thanks for the link; I had not seen it.

Will drop it in v4. The dump agrees with my read of the file.

Will add vreg_l7b_2p8 and avdd-supply in v4.

One question for dvdd. The sensor's DVDD pin is 1.2 V, so a regulator
on the module or the board must step it down. On the schematic, which
rail feeds that regulator: L7B, as Tudor's patch has it, or the 1.8 V
behind GPIO 91? That decides whether dvdd-supply goes on vreg_l7b_2p8
or on vreg_cam_1p8.

Thanks,
Liviu
