[PATCH 4/5] ASoC: codecs: ad193x: Add runtime support for DSP_A and I2S modes

From: Codrin.Ciubotariu
Date: Mon Feb 18 2019 - 11:10:46 EST


From: Codrin Ciubotariu <codrin.ciubotariu@xxxxxxxxxxxxx>

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.
