From a5c6951c49fbf7509419d877620625ca3cdae9b1 Mon Sep 17 00:00:00 2001 From: Robert Jarzmik Date: Wed, 13 Sep 2017 21:37:17 +0200 Subject: mfd: wm97xx-core: core support for wm97xx Codec The WM9705, WM9712 and WM9713 are highly integrated codecs, with an audio codec, DAC and ADC, GPIO unit and a touchscreen interface. Historically the support was spread across drivers/input/touchscreen and sound/soc/codecs. The sharing was done through ac97 bus sharing. This model will not withstand the new AC97 bus model, where codecs are discovered on runtime.
