Right, in the imx219, on exit from s_power(), the clock and data lanes must be placed in the LP-11 state. This has been done in the ov5640 and tc358743 subdevs.
If we want to bring in the patch that adds a .prepare_stream() op, the csi-2 bus would need to be placed in LP-11 in that op instead.
Philipp, should I go ahead and add your .prepare_stream() patch?
