Subject: [PATCH 9/9] usb: {ohci,ehci}-platform: Use new OF big-endian helper function
Date: Tue, 25 Nov 2014 16:49:54 -0800	[thread overview]
Message-ID: <1416962994-27095-10-git-send-email-cernekee@gmail.com> (raw)
In-Reply-To: <1416962994-27095-1-git-send-email-cernekee@gmail.com>

This handles the existing "big-endian" case, and in addition, it also does
the right thing when "native-endian" is specified.
