Subject: [PATCH 3/3] ARM: dove: remove temporary clock and non-DT device probing
Date: Thu, 15 Aug 2013 15:24:19 +0200	[thread overview]
Message-ID: <1376573059-15055-4-git-send-email-sebastian.hesselbarth@gmail.com> (raw)
In-Reply-To: <1376573059-15055-1-git-send-email-sebastian.hesselbarth@gmail.com>

With OF clock providers, we can now remove temporary clocks and clock
aliases. Also, non-DT device probing for timer and serial is removed.
