[alsa-devel] [PATCH v2] ASoC: omap: convert per-board modules to platform drivers
Mans Rullgard
mans.rullgard at linaro.org
Thu Sep 8 19:34:56 CEST 2011
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 at linaro.org>
---
Platform device names fixed.
N8x0 changed to get clocks before registering card.
