video processing front end mutex usage and parameter passing

Hi, In reviewing vpfe_capture.c, we are seeing some code that seems wrong. We don't fully understand when the VPFE device lock needs to be held, but it seems the lock is not used consistently. Also in some cases we found a pointer to a structure was passed in as a parameter and instead of

Status of DM6446 support in

Sekhar, I have been seeing some DM6446 related activity on this list. We need to update from 2.6.18 to something more recent for the DM6446. Do you have a suggestion on what kernel source would be best to use as our starting point (maybe a tag on linux-davinci repo)? Are you away of any

DM365 deep sleep

Sekhar, What is the status for deep sleep support on the DM365? If it is available, where can I find it? If not available, I was planning on starting adding DM365 deep sleep support using the mach-davinci pm.c and sleep.S code from the latest davinci-linux git repo unless you have another

[PATCH 2/2] TPS6507x touch screen driver board specific initialization values.
