commit: 16337e028a6dae9fbdd718c0d42161540a668ff3 From: Daniel J Blueman <[email protected]> Date: Sun, 4 Nov 2012 13:19:03 +0800 Subject: ALSA: HDA: Fix digital microphone on CS420x
Correctly enable the digital microphones with the right bits in the right coeffecient registers on Cirrus CS4206/7 codecs. It also prevents misconfiguring ADC1/2. This fixes the digital mic on the Macbook Pro 10,1/Retina.
