Subject: [PATCH v2 1/2] ASoC: dt-bindings: rockchip-i2s: add an optional property "i2s_clk_out"
Date: Wed,  3 Dec 2014 15:18:37 +0800	[thread overview]
Message-ID: <1417591118-18695-2-git-send-email-jay.xu@rock-chips.com> (raw)
In-Reply-To: <1417591118-18695-1-git-send-email-jay.xu@rock-chips.com>

Add an property "i2s_clk_out", which enables to output clock to outside
of rockchip SoCs. Let's make it optional since not each board needs it.
