Difference between ADV7511 and ADV7511W

Hi,

I would like to know the difference between ADV7511 and ADV7511W.

I have to implement the ADV7511W i2c driver in Linux, but Linux BSP source code is having adv7511.c file. Is this file compatible to adv7511w. Please tell me the difference and support to implement the Linux driver code for adv7511w.

Thanks & Regards,

Ramanjineyulu.

  • Hi Guenter,

    Thanks for your reply.

    In Linux BSP adv7511.c driver code is there it is located at "drivers/media/i2c/adv7511.c" is this driver is compatible to adv7511w. I have taken this file into temporary directory and written Makefile, compiled this driver as a module and generated adv7511.ko file. When I insert this module its getting error.
