Subject: ASoC CODEC power management on reboot
Date: Mon, 22 Jun 2009 12:13:23 +0100 [thread overview]
Message-ID: <20090622111323.GM14476@trinity.fluff.org> (raw)
I've run into a problem where when the system reboots the audio
starts playing random data. I suspect that this is due to the CODEC
being left powered and when the during/after the reset process the
GPIO lines which form the I2S bus are left floating.
Should the ASoC (possibly DAPM) layer sort out powering down the CODEC
before reboot, or should it be down to the codec or the mapping driver
to do this?
