Subject: [PATCH V6 3/3] ASoC: fsl_asrc: Unify the supported input and output rate
Date: Mon, 22 Apr 2019 04:52:08 +0000	[thread overview]
Message-ID: <aa3757e2fb4ec4e1cf2b1fe3de651257a2a89350.1555908545.git.shengjiu.wang@nxp.com> (raw)
In-Reply-To: <cover.1555908545.git.shengjiu.wang@nxp.com>

Unify the supported input and output rate, add the
12kHz/24kHz/128kHz to the support list
