From c001bf633a910cfc8a5b84b80634db4636bf1724 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Tue, 14 Nov 2017 01:04:08 +0000 Subject: [PATCH] ASoC: use internal reg_cache on uda1380 Codec reg_cache is legacy feature and very few driver only are using it. But, ALSA SoC framework needs to support it. Codec will be merged into Component in the future, so, let's remove legacy and unused feature from framework. This patch implements ALSA SoC reg_cache feature into driver, and don't use ALSA SoC framework's feature.
