Subject: [PATCH V1 1/2] ASoC: fsl: esai: refine esai for tdm support
Date: Wed, 6 Aug 2014 18:23:03 +0800 [thread overview]
Message-ID: <e68d8fbaaed7000b13688b0f1757b5b9557889d7.1407320232.git.shengjiu.wang@freescale.com> (raw)
In-Reply-To: <cover.1407320232.git.shengjiu.wang@freescale.com>
Add parameter for slots, and caculate the number of TX/RX pins and bclk with
slots. Then driver will be compatible with slots > 2 in TDM mode.
