Subject: [RFC PATCH 11/14] ASoC: qcom: Add apq8016 lpass driver support
Date: Thu, 30 Apr 2015 18:17:59 +0100 [thread overview]
Message-ID: <1430414279-11342-1-git-send-email-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <1430414148-10869-1-git-send-email-srinivas.kandagatla@linaro.org>
This patch adds apq8016 lpass driver support. APQ8016 has 4 MI2S which
can be routed to one internal codec and 2 external codec interfaces.
Primary, Secondary, Quaternary I2S can do Rx(playback) and Tertiary and
Quaternary can do Tx(capture).
