Subject: [PATCH 1/2] ASoC: rockchip-i2s: dt: add i2s_clkout to list of clocks
Date: Wed, 19 Nov 2014 11:06:04 +0800 [thread overview]
Message-ID: <1416366365-4632-2-git-send-email-jay.xu@rock-chips.com> (raw)
In-Reply-To: <1416366365-4632-1-git-send-email-jay.xu@rock-chips.com>
Add i2s_clkout property, which enables output clock to chip outside,
this is generally for audio codec outside.
Also add it to example.
