    The device ID should be 0xd300. This is the actual value read from the switch regs.
    This also requires an entry in the 'b53_switch_chips' structure in b53_common.c.

    Other wise this patch set looks good.

    I was testing a similar change (except for the above, which doesn't
    affect the functionality) to get the switch working and it works.

    Thanks
