Subject: [PATCH 6/8] ata: ahci_brcm: Add a shutdown callback
Date: Tue, 10 Dec 2019 10:53:49 -0800 [thread overview]
Message-ID: <20191210185351.14825-7-f.fainelli@gmail.com> (raw)
In-Reply-To: <20191210185351.14825-1-f.fainelli@gmail.com>
Make sure that we quiesce the controller and shut down the clocks in a
shutdown callback.
