[srinivasanshanm]

Hi,

As am newbiee to this I.mx28 BSP's , & new to audio amp & AM/FM tuner, I found there are no drivers for audio amplifier ( TDA7563B Audio Amp) & (Si4743 AM/FM tuner ) interfaced through i2c in L2.6.35_10.12.01_ER_source, could you pls let me know how to get started with it or if we have any other drivers for the same,

Thanks in advance,

Awaiting for your replies,

On i.MX28 EVK, the audio codec is SGTL5000 where the control is also via I2C interface. It is enabled by default in Linux BSP. You may port the TDA753B driver by taking the SGTL5000 as the reference. Please also check your vendor if they already have linux driver code for their chips.
