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

If it's too difficult to get the imx219 csi-2 transmitter into the
LP-11 state on power on, perhaps the csi-2 receiver can be a little
more lenient on the transmitter and make the LP-11 timeout a warning
instead of error-out.

Can you try the attached change on top of the version 5 patchset?

If that doesn't work then you're just going to have to fix the bug
in imx219.
