3.18.1->3.19-rc2: In-band Error seen by MPU

["Peter Kümmel" <syntheticpp@gmx.net>]

When updating (custom DM3730 board) from 3.18.1 ro 3.19-rc2 I see a "In-band ERROR" warning which wasn't present in 3.18.1.
Could it be that I missed some DT updates?

And  should I care of "irq: no irq domain found for /ocp/pinmux@48002030"?

Many thanks!
