Now, that cleans it up nicely! I thought that was fishy :-)

[PATCH 3/4 v9] TVP7002 driver for DM365
From: Santiago Nunez-Corrales
This patch provides the implementation of the TVP7002 decoder
driver for DM365. Implemented using the V4L2 DV presets API.
Removed shadow register values. Testing shows that the device
needs not to be powered down and up for correct behaviour.
