Subject: [PATCH 2/2] ARM: dts: Add sound node for Peach-pit board
Date: Thu, 24 Apr 2014 11:46:59 +0530	[thread overview]
Message-ID: <1398320219-23362-3-git-send-email-tushar.behera@linaro.org> (raw)
In-Reply-To: <1398320219-23362-1-git-send-email-tushar.behera@linaro.org>

The audio setup on Peach-pit board is similar to Snow board, hence the
sound-card driver used on Snow board can be reused on Peach-pit board.

Peach-pit board uses MAX98090 audio codec.
