OMAP 2 camera driver + other stuff

Hello,

I'm about to send new patches of OMAP 2 camera driver, OMAP 
camera/sensor interface and TCM825x sensor to the V4L2 list. They are 
modified versions of older drivers from Montavista (camera) and INdT 
(sensor).

Both drivers use a modified camera/sensor interface. The original 
interface has been used in the OMAP 1 and older OMAP 2 camera drivers 
and associated sensor drivers. (The original interface plus other 
related stuff can be found under the same name in linux-omap tree in 
git://source.mvista.com/git/linux-omap-2.6.git .)

These patches are against the vanilla Linux kernel and they contain just 
the drivers and the interface without machine-specific parts i.e. they 
are not usable as such.

Especially the interfaces between camera and sensor are important. Now 
the camera interface structure is a global variable (omap24xxcam in 
omap24xxcam.c) to which the sensor driver will get a pointer as a part 
of its machine-specific configuration. Do you think this is okay?

The other subject of interest is IMO the camera driver. Currently mmap, 
vbq and DMA parts are a bit ugly. Luckily they are not in any kind of 
central role in the driver.

The sensor driver is there mostly as a reference.

Comments about the patches are most welcome.

Especially to Trilok and Khasim: there are not so much changes between 
these and the ones I sent to linux-omap-open source, mostly cleanups and 
reset handling updates. And the number of files is smaller again. ;)

Regards,
