Subject: [PATCH v2 5/5] ARM: bcm2835: Add the Raspberry Pi power domain driver to the DT.
Date: Fri, 4 Dec 2015 09:45:48 -0800 [thread overview]
Message-ID: <1449251148-19344-6-git-send-email-eric@anholt.net> (raw)
In-Reply-To: <1449251148-19344-1-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.
