From 9b0a25f0386f9775b69c46ced9b5632b649f00ba Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 7 Mar 2011 08:04:55 +0100 Subject: ASoC: neo1973_wm8753: Move lm4857 specefic code to its own module This patch moves the code for the lm4857 AMP from the neo1973_wm8753 sound board driver to its own module. The lm4857 is a generic AMP IC and not specific to the neo1973.

They both use the same codec with the same routing to the gsm modem and bluetooth chip. But they do use different AMPs though and there are some minor differences in the speaker setup. As a result most of the code of those two drivers is identical. So from a maintenance point of view it makes sense to merge them into a single driver. It also reduces the size of kernel images supporting both the GTA01 and GTA02. As a side-effect of this merge the GTA01 for example gains support for routing audio to and from the bluetooth DAI.

The patch also modifies the neo1937_wm8753 sound board driver to use the new driver instead of registering the bluetooth DAI manually. Previously there was a name mismatch between the bluetooth DAI and the bluetooth DAI link and the sound card was not instantiated, with this patch the issue is no longer present and sound support works again.
