Hi ,
Our Am3351 custom board has TLV320AIC3100 codec interface. We are facing problem in getting BCLK and LRCLK from the codec. Here we configured codec as master and McAsp as slave.

When kernel boot, audio card is get detected and it is list in aplay -l
During audio play, codec driver initialized as follow,
tlv320aic31xx-codec 1-0018: ## aic31xx_set_dai_sysclk: clk_id = 0, freq = 24000000, dir = 1
tlv320aic31xx-codec 1-0018: ## aic31xx_hw_params: width 16 rate 48000
tlv320aic31xx-codec 1-0018: pll 8.1920/2 dosr 128 n 8 m 2 aosr 128 n 8 m 2 bclk_n 8
But after this it is getting hang and does not setting the bias level to make PLL core on.
