--------------------------------
[ Upstream commit 63e5aa69b821472a3203a29e17c025329c1b151f ]
The TLV320AIC3106 audio codec is interfaced on the i2c-1 bus. With the default rate of 400Khz the i2c register writes fail to sync:
[ 36.026387] tlv320aic3x 1-001b: Unable to sync registers 0x16-0x16. -110 [ 38.101130] omap_i2c 20010000.i2c: controller timed out
Dropping the rate to 100Khz fixes the issue.
