Subject: GPIO control from ALSA
Date: Wed, 20 Apr 2016 10:03:48 +0200	[thread overview]
Message-ID: <571737E4.5030908@barix.com> (raw)

Hello,

I'm writing a driver for ASoC "sound card" hardware which uses CPU GPIO 
to mute/unmute an analogue amplifier and another GPIO to control an 
analogue switch for line/mic switching. Is there an abstraction in ALSA 
to model this kind of hardware?

Thanks
Petr
