DM814x V4L2 driver implementation inputs

Prodigy 10 points

Hi,

I am using TI814x processor, linux kernel(or psp) has support of Fbdev and VPSS components and also support FVID2 interface.

The v4L2 driver is required to display the decoded video data on LCD screen and the LCD working fine with the graphics input data.

As my understanding  the v4l2 driver needs the interafce/support from VPSS/FVID2 components to interact with the binary running on M3 side.

For the implementation of V4L2 driver for TI814x, which is better example source to refer (many examples like davinci, omap4 exist - whose code flow similar to TI814x).

How the v4l2 related platform device and overall device structure and per device structure to be declared and provide some pointers to it.

 

Regards,

anil

    Hi,

    All board/platform related data structures for vpss drivers are defined in arch/arm/mach-omap2/ti81xx_fb.c or ti81xx_vpss.c based on release you are using. Media controller binary doesnt touch any of platform/board dependent structures. Its all done with Linux drivers.
