Subject: [PATCH v3 0/2] ata: ahci_brcm: Fix use of BCM7216 reset controller

v3 -- discard commit from v2; instead relay on the new function
      reset_control_rearm provided in a recent commit [1] applied
      to reset/next.
   -- New commit to correct pcie-brcmstb.c usage of a reset controller
      to use reset/rearm verses deassert/assert.

v2 -- refactor rescal-reset driver to implement assert/deassert rather than
      reset because the reset call only fires once per lifetime and we need
      to reset after every resume from S2 or S3.
   -- Split the use of "ahci" and "rescal" controllers in separate fields
      to keep things simple.

v1 -- original


[1] Applied commit "reset: make shared pulsed reset controls re-triggerable"
    found at git://git.pengutronix.de/git/pza/linux.git
    branch reset/shared-retrigger
