+Subject: ata: ahci_brcm: Allow optional reset controller to be used
+
+From: Florian Fainelli <f.fainelli@gmail.com>
+
+commit 2b2c47d9e1fe90311b725125d6252a859ee87a79 upstream.
+
+On BCM63138, we need to reset the AHCI core prior to start utilizing it,
+grab the reset controller device cookie and do that.
