From 25acf553aeed86f93f2cf39227b59fc6eb3e8c78 Mon Sep 17 00:00:00 2001 From: Chaithrika U S Date: Fri, 5 Jun 2009 06:28:08 -0400 Subject: davinci: ASoC: Add the platform devices for ASP 1) Registers the platform devices for ASP on dm355, dm644x and dm646x so that the machine driver can probe to get ASP related platform data. 2) Move towards definition of the asp clocks using physical name(for dm355 and dm644x) 3) Add platform data to board specific files.
