Just like with version 4, version 5 is completely useless with IMX219:

imx6-mipi-csi2: LP-11 timeout, phy_state = 0x00000200
ipu1_csi0: pipeline start failed with -110
imx6-mipi-csi2: LP-11 timeout, phy_state = 0x00000200
ipu1_csi0: pipeline start failed with -110
imx6-mipi-csi2: LP-11 timeout, phy_state = 0x00000200
ipu1_csi0: pipeline start failed with -110

So, like v4, I can't do any further testing.

Is the imx219 placing the csi-2 bus in LP-11 state on exit
from s_power(ON)?

I realize that probably means bringing the chip up to a
completely operational state and then setting it to stream
OFF in the s_power() op.

The same had to be done for the OV5640.
