I raised the same query when Andrey sent an off-list copy to me by
mistake - he said that in future he intends to extend the driver to 
have additional features not present on the EVM (though for me that
could always change the || later).

Andrey, with Linux kernel patches reply to all is generally the way
forward.

Mark,

Understood. Shall I change if if to if || then?

Honestly I'm not that bothered, I was mostly following up to the list so
that readers and the archives could see the answer to the query (I
guessed you may have mistakenly replied off list).

This doesn't apply against current ASoC.  Could you please regenerate
against this branch:

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound-2.6.git for-2.6.33

Hi,

I wish I knew how to do this. I'm new with git and anly learn how to
work with one tree.
Complex operations confuse me a little. I generated something, but it
doesn't look different from what I had before.

P.S. Reading alsa-project wiki didn't shed more light. For my main tree
is davinci tree and git is damn tricky.

Hi Mark,

Are you sure you have the latest davinci soc support in your tree?
Mine file davinci_evm.c is 7.5k size, in your

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound-2.6.git

repo your is 5.5k. Quick glance shows that in your repo davinci support
lacks of da830_evm support.
I'm confused which one is I have to use and apply patch to?

Please, disregard my previous message. It's me stupid enough to forget
