Lars-Peter Clausen May 27, 2014, 8:53 a.m. UTC
The ADAU1X61 and ADAU1X81 are very similar in the digital domain, but are quite
different in the analog domain. This patch adds support for the common parts of
the ADAU1X61 and ADAU1X81 CODECs.

The patch also restores some of the alphabetical order in the Makfile and
Kconfig.

Applied all, thanks.  We really ought to be able to get simple card to
be able to set up the PLLs for the cards but that's a separate issue.

As ever please try to keep the lines on your commit messages a little
shorter.

I ended up adding following into my ~/.vimrc after accidentally creating 
commit message couple times in a wider terminal:

autocmd Filetype gitcommit set textwidth=76

Not sure is that possible to do independently from editor.
