From fb509fa962243e20bddcc5cab74c4a2153c01ff6 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Tue, 8 May 2018 17:35:50 +0200 Subject: ASoC: rt5640: Allow specifying dmic data pins through device-properties Allow specifying dmic data pins through device-properties / dt. This will allow us to stop exporting rt5640_dmic_enable() once all callers of it have been converted to setting device-properties for this instead.
