[PATCH 14/17] ARM: ux500: Rename MSP board file to something more meaningful
Lee Jones
lee.jones at linaro.org
Fri Aug 24 10:01:50 EDT 2012
The 'msp' board file does more than just register MSP devices. It
also registers some other components necessary to get audio working
on ux500 based platforms; such as the PCM and Machine Drivers. For
that reason we're changing the filename to be more encompassing -
'audio'.
