With this version, I get:

[28762.892053] imx6-mipi-csi2: LP-11 timeout, phy_state = 0x00000000
[28762.899409] ipu1_csi0: pipeline_set_stream failed with -110

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?
