Thanks Jarkko for the support. I have applied the patch. I am kernel 2.6.29. In my board CLKR and FSR are connected so I am calling functions as: snd_soc_dai_set_sysclk(cpu_dai, OMAP_MCBSP_CLKR_SRC_CLKR, 0, SND_SOC_CLOCK_IN); snd_soc_dai_set_sysclk(cpu_dai, OMAP_MCBSP_FSR_SRC_FSR, 0, SND_SOC_CLOCK_IN); I checked pin muxing is also fine but still I am getting the same error.
