+From: Mark Brown <broonie@opensource.wolfsonmicro.com>
+Subject: [PATCH] ARM: S3C64XX: Define some additional always off clocks
+
+Add entries to clocks_off for some additional clocks which are not
+currently used by any mainline drivers. They default on at power up
+but are never actually used so
+
+If these blocks are actually supported some of these bindings would need
+to be redone properly, for example hooking up to the muxes that use them,
+but that can be done incrementally.
