I've just tried to apply your patch as the series seems about to be
merged. After the resolution of a few merge conflict it was applied.

But I still have a problem see below:

With this line you created a dependency with the patch "irqchip:
irq-mvebu-icu: new driver for Marvell ICU". And without it the dtb is
not buidable.

So either I wait for the next kernel release to apply it or I will need
a stable branch with the commit adding the mvebu-icu.h file.
