* Peter Ujfalusi [off-list ref] [160209 03:48]:
The tlv320aic3104 codec's master clock is coming from the SoC's CLKOUT2. Select the SYS_CLK2 (via divider) as parent clock for CLKOUT2 and select the same clock (SYS_CLK2) for McASP3 AHCLKX clock as well. SYS_CLK2 is sourced from an external oscillator running 22.5792MHz and it is coming in to the SoC via the X1_OSC1. Signed-off-by: Peter Ujfalusi <redacted>
Applying into omap-for-v4.5/fixes thanks. Tony
