It mentions a dependency, which makes it harder to apply.  I see that
dependency seems to have been applied, so maybe post an updated
version of the series, including both patches.

The series touches both ATA and PCI, so not immediately obvious where
it should go.  It looks like the ATA part is bigger, but only 2/2 went
to linux-pci, so it's harder to figure this out than it should be.  I
poked around a bit on lore, but I can't find 1/2 at all:

  https://lore.kernel.org/linux-arm-kernel/20201216214106.32851-1-james.quinlan@broadcom.com/

Maybe also include Nicolas Saenz Julienne <nsaenzjulienne@...e.de>
directly in "To:".  I know I look at stuff addressed directly to me
first; the "CC:" flood gets overwhelming fast.  I assume Lorenzo will
look for at least an ack from Nicolas before doing anything.

If you repost, it's nice if you match existing style, e.g.,

  - PCI: brcmstb: use reset/rearm instead of deassert/assert
  + PCI: brcmstb: Use reset/rearm instead of deassert/assert
