The sys_nirq2 is used for twl6040, make sure the pin is configured
correctly.

Should remove the boot-loader pin-muxing dependency.
Was this the reason, Audio had some issues on OMAP4430
SDP as reported by Russell ?

FWIW:

The boot loader never configured the sys_nirq2, I have sent a patch for u-boot
to do this, but it is said that the kernel should take care of this.

We did not had jack detection working with upstream u-boot, kernel (I have
patched u-boot so I have not seen this issue).
Now if the board is booted without HS connected, upon connecting the HS we
will recognize it and it should be all fine.
So yes this was the reason why Russell had issues with audio.

Thanks Peter for tracking it down.

Please ignore this two patch, I'll resend them with the correct MUX config.
By mistake I have set MUX_MODE1, while it must be set MUX_MODE0.
It was working with MUX_MODE1, but it is not aligned with the TRM...

Sorry,
Péter
