Subject: [PATCH] audio:am3517evm support for AIC23

This patch aims to fix the registration of the AIC23-based audio
module on the AM3517-EVM, with the following two changes:

1. The i2c_board_info entry supporting aic23 codec was added into
the i2c2 bus.
2. The i2c client device name (".2-001a" in this case, including
the separator period) was appended to the codec_name member of
am3517evm_dai to resolve the names mismatch happening in
soc_bind_dai_link().

First, your patch does the correct things.

I investigated a bit and it looks like the sound/soc/omap/am3517evm.c
never worked in mainline since the patch below adding codec to
board-am3517evm.c wasn't applied by reason or another.

This means that you should split this patch into two and they can be
sent as independent patches. am3517evm.c change via alsa-devel
and board-am3517evm.c via linux-omap & linux-arm-kernel. Some comments
below.

This is ok and don't need anything else as the rest pieces from
original missing patch are added by another patches.

Subject for this part could be something like
"ASoC: AM3517: Update codec name after multi-component update".

Remember to cc ASoC maintainers Mark Brown and Liam Girdwood.

You could add my acks to splitted patches.
