Subject: CHROMIUM: ALSA: ASoC: max98095 0 Add built in EQ for 44.1k and 48k.
X-Git-Url: http://git.cascardo.eti.br/?a=commitdiff_plain;h=b5d52a499b5b443e43c614af59fec1536cb973bb;p=cascardo%2Flinux.git

CHROMIUM: ALSA: ASoC: max98095 0 Add built in EQ for 44.1k and 48k.

EQ setting supplied by Maxim after tuning a snow PVT device.
We need to move this to device tree eventually, but Samsung says it is
important for speaker protection to get it in right away.

BUG=chrome-os-partner:12039
TEST=listen to youtube with EQ enabled and disabled.
