Subject: [PATCH] ASoC: omap: convert per-board modules to platform drivers
This converts the per-board modules to platform drivers for a
device created by in main platform setup. These drivers call
snd_soc_register_card() directly instead of going via a "soc-audio"
device and the corresponding driver in soc-core.
Signed-off-by: Mans Rullgard <mans.rullgard@...aro.org>
---
Tested on Beagleboard. Other boards only compile-tested.
