Mark, I have always viewed alsa drivers as split to two parts

1. the "PC world" where mostly individual often amateur developers post 
patches improving support of the hardware they own.

2. the ASoC world of embedded solutions, where mostly vendors contribute 
patches for the hardware they produce. All ASoC posts are prefixed by 
ASoC and I have always viewed them as something I do not have to care 
about when fixing and developing stuff for PCI.

Even the until recently highly active intel-hda section does not use any 
of the ASoC infrastructure. If you read the ASoC documentation 
http://alsa-project.org/main/index.php/ASoC, it would not occur to me I 
should be using asoc codecs infrastructure for ice1724 card.

If you want these independent contributors to start using the kernel 
infrastructure common in the ASoC "tree", please tell them clearly on 
the alsa-project.org website, at best directly at 
http://alsa-project.org/main/index.php/Developer_Zone

Working hard on series of patches and being met with cold attitude as 
for not adhering to ASoC standards (quoting the alsa-project.org: "The 
overall project goal of the ALSA System on Chip (ASoC) layer is to 
provide better ALSA support for embedded system on chip procesors") the 
developer had no idea he was supposed to follow is not really 
motivating. And I think every helpful hand and brain counts here.

I can understand the very active ASoC subproject is defining current 
standards for the rest of alsa tree but please tell the currently valid 
rules to all the developers.

Thanks a lot for understanding,

Pavel.
