[alsa-devel] [PATCH v3 2/6] ARM: DaVinci: ASoC: Add the platform devices for ASP
Chaithrika U S
chaithrika at ti.com
Thu May 28 11:09:34 CEST 2009
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 phyisical name(for dm355 and
dm644x)
3) Add platform data to board specific files.
