From dd2ceb1a4028dc9644ed4df80cea9c05ca0b5f6d Mon Sep 17 00:00:00 2001 From: Muralidharan Karicheri Date: Fri, 3 Jul 2009 05:23:07 -0300 Subject: V4L/DVB (12250): v4l: dm355 ccdc module for vpfe capture driver Adds ccdc hw module for DM355 CCDC. This registers with the bridge driver a set of hw_ops for configuring the CCDC for a specific decoder device connected to vpfe.
