Hi Mauro,
Please pull from http://www.linuxtv.org/hg/~hverkuil/v4l-dvb-vpfe-cap for the following:
- tvp514x: Migration to sub-device framework
- tvp514x: formatting comments as per kernel documentation
- v4l: vpfe capture bridge driver for DM355 and DM6446
- v4l: ccdc hw device header file for vpfe capture
- v4l: dm355 ccdc module for vpfe capture driver
- v4l: dm644x ccdc module for vpfe capture driver
- v4l: ccdc types used across ccdc modules for vpfe capture driver
- v4l: common vpss module for video drivers
- v4l: Makefile and config files for vpfe capture driver
- v4l: davinci drivers should only be compiled for kernels >= 2.6.31.
Hopefully these changes can be merged into 2.6.31.
I have attached two arch/arm patches that need to be applied to the git tree.
These patches should be applied after merging this tree.
I've compiled this driver against the latest Linus' git tree.
Thanks,
Hans
