Subject: [PATCH v3 4/4] ARM: bcm2835: Add the Raspberry Pi power domain driver to the DT.
Date: Tue, 15 Dec 2015 13:40:22 -0800 [thread overview]
Message-ID: <1450215622-27394-5-git-send-email-eric@anholt.net> (raw)
In-Reply-To: <1450215622-27394-1-git-send-email-eric@anholt.net>
From: Alexander Aring <alex.aring@gmail.com>
This connects the USB driver to the USB power domain, so that USB can
actually be turned on at boot if the bootloader didn't do it for us.
