Here probes and plays from headset fine on top of
1c999c47a9f1 Merge tag 'dm-3.19-fixes-3' of
git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
I have above patches and these two:
http://marc.info/?l=devicetree&m=142264840506833&w=2
http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=8294/1
Your error code -121, -EREMOTEIO suggests that chip doesn't acknowledge
its address on i2c bus when trying to communicate with it. I don't know
what can cause it. Could it be some timing or probe ordering issue? I
have CONFIG_I2C_OMAP=y and sound drivers including
CONFIG_SND_SOC_TPA6130A2 as modules.
