From fd94eeef06ed4abc08f58e42f46341d0bc4f7793 Mon Sep 17 00:00:00 2001 From: Harsha Priya Date: Fri, 28 Jan 2011 22:26:53 +0530 Subject: [PATCH] ASoC: sn95031: add capture support This patch adds the support for capture path in sn95031 codec. This codec supports upto 6DMICs, 2 AMICs and Linein. The linein and AMICs are connected through a MUX to ADC. The TX paths can be assigned to any of the ADCs or DMICs.
