In order to have audio functional on mx6qsabrelite, it is necessary to setup
the IOMUX for MX6Q_PAD_GPIO_0__CCM_CLKO pins as it provides the audio clock.

The commit messages should generally be wrapped at column 72.  I fixed
it up and queued the patch for 3.6-rc.  Thanks.

Ok, thanks.

With this patch applied audio is probed correctly now:

sgtl5000 0-000a: Using internal LDO instead of VDDD
sgtl5000 0-000a: sgtl5000 revision 0x11
imx-sgtl5000 sound.11:  sgtl5000 <-> 2028000.ssi mapping ok

,but I get error during aplay:

,and I guess this happens because of the missing mx6 sdma firmware.

Where can I get the mx6 sdma firmware binary from?

Thanks,
