From bccf9c7e14830af0004399d42d861b33c92eacff Mon Sep 17 00:00:00 2001 From: Codrin Ciubotariu Date: Mon, 18 Feb 2019 16:10:34 +0000 Subject: [PATCH] ASoC: codecs: ad193x: Add runtime support for DSP_A and I2S modes The driver only supports DPS_A for DAC, which is configured at probe. This patch adds support for DSP_A and I2S modes by using the set_fmt() callback. A trivial break is also removed from a case's default branch.
