But this will not work for a 7445-based chip or other BCM7xxx chips that either have a memory region extension or a non-zero system memory offset. IIRC, similar regulator code was submitted before as part of the complete driver that could handle our curious DMA situation, but was rejected because someone objected to us using a generic list of regulators without specific explanation for each in the device tree documentations.
