We're using imx_v6_v7_defconfig on our Wandboards. After upgrading to v4.14.67, reboot no longer works (or, well, takes a very long time when the watchdog is configured).

v4.14.66 works fine, the breakage bisects to 2059e527a659cf16d6bb709f1c8509f7a7623fc4 (ARM: imx_v6_v7_defconfig: Select ULPI support), and reverting that on top of v4.14.67 again works.

FWIW, v4.18 (the mainline release containing the upstream commit 157bcc0609) works fine, while v4.17.19 which also has that commit backported (as df06ca1f56) fails. So I'm guessing there must be some other commits in v4.18 that happen to make imx_v6_v7_defconfig work.

Thanks for reporting.

Commit 157bcc06094c3 ("ARM: imx_v6_v7_defconfig: Select ULPI support") was meant to be applied for 4.18 only.

I think we should revert it from earlier stable versions.

Or a better solution would be to port a930d8bd94d8db7715d1af74299f710b1fb22fc8 from upstream.

Please test the attached patch adjusted for 4.14.67.

Thanks
