Yes, I inserted the driver, but I didn't use any device-tree for this device. To be completely honest I read the AD9834 Analog wiki page, I thought about adding the ad9834_platform_data and spi_board_info but then I saw that the ad9834_platform_data structure was removed in commit 80109c32, so I thought 'I'm missing something...' that's why I asked. I will try using the files in the Analog tree you pointed to. Thanks a lot!
