Subject: [PATCH 1/7] ARM: dts: sunxi: Add regulator-boot-on property to ahci-5v regulator
Date: Thu, 13 Nov 2014 09:31:43 +0000 [thread overview]
Message-ID: <1415871109-28332-1-git-send-email-hdegoede@redhat.com> (raw)
This avoids it getting briefly turned off between when the regulator getting
registered and the ahci driver turning it back on, thus avoiding the disk
going into emergency head park mode.
