Subject: [PATCH] ARM: dts: am335x-wega: Add audio support
Date: Wed, 10 Aug 2016 17:12:15 +0200	[thread overview]
Message-ID: <1470841935-14190-1-git-send-email-s.mueller-klieser@phytec.de> (raw)

The wega board has a TLV320AIC3007 connected via McASP0. In the default
configuration, no external crystal is mounted. We run a system clock of
25 MHz, so we use the audio codec PLL for audio clock generation.
