    Hey Aaro.

    It is actually two patches that cause the breakage. The other is:

    commit e55aeb6ba4e8cc3549bff1e75ea1d029324bce21
    of/irq: Mark interrupt controllers as populated before initialisation

    I needed to revert both of these in order to get MMC working on our 71xx
    and 78xx boards. For our MMC, I got error messages from the MMC core of
    "Invalid POWER GPIO" until I applied the second patch. I will have a fix
    worthy of upstreaming today which will be posted today.
