Subject: ALSA: hda - Add support for MacBook Pro 10,1
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ef596a57b4d7d8b258beb570ed309ef85bf24dd1;p=linux-beck.git

ALSA: hda - Add support for MacBook Pro 10,1

MacBook Pro 10,1 needs a few adjustments to make it working:
- more COEF verbs
- some pin config overrides to disable the unused pin (0x0d, 0x12),
  and fix the internal mic (0x0e)

In addition, it uses GPIO 1 and 3 like other MacBooks.

The internal digital mic on the machine is still problematic: it seems
that only the right channel is used and the left is always static.
This looks like a hardware design, so we need to cope in the software
side somehow...

The primary information and test were brought from Daniel J Blueman.
