X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a5fe6be42e5cadac4c2aef2b3714cfa8fadb6092;p=linux-beck.git

ASoC: Tegra: Enable Kaen HP_MUTE at boot

We want the default state of the HP_MUTE signal to be asserted, so that
the headphones are muted before the first audio playback. Without this,
the headphones are left unmuted until shortly after the first audio
playback completes.
