From: Victor Rodriguez <victor.rodriguez@xxxxxxxxxx>
This patch adds sound support for the Hawkboard-L138 system
It is under the machine name "omapl138_hawkboard".
This system is based on the da850 davinci CPU architecture.
Signed-off-by: Victor Rodriguez <victor.rodriguez@xxxxxxxxxx>

Notes:
This patch works with da8xx_omapl_defconfig
In order to test ALSA utils select in menuconfig like insmodule:
Sound card support --->
Advanced Linux Sound Architecture --->
ALSA for SoC audio support --->
SoC Audio for the TI DAVINCI chip
SoC Audio support for DA850/OMAP-L138 EVM/Hawkboard
