From: Vaibhav Hiremath <hvaibhav@xxxxxx>
This is second version of OMAP3EVM Mulit-Media/Mass Market
Daughter Card support.
Fixes:
- Cleaned unused header files, struct formating, and unused
comments.
- Pad/mux configuration handled in mux.ch
- mux.ch related changes moved to seperate patch
- Renamed file board-omap3evm-dc.c to board-omap3evm-dc-v4l.c
to make more explicit.
- Added some more meaningful name for Kconfig option
TODO:
- Camera sensor support (for future development).
- Driver header file inclusion (dependency on ISP-Camera patches)
I am working with Sergio to seperate/move header file to standard
location.
- Still need to fix naming convention for DC
Tested:
- TVP5146 (BT656) decoder interface on top of
Sergio's ISP-Camera patches.
- Loopback application, capturing image through TVP5146
and saving it to file per frame.
- Basic functionality of HSUSB Transceiver USB-83320
