From cdab0d4ecc1a890aece7102c2074bf73175b9935 Mon Sep 17 00:00:00 2001 From: Anatol Pomozov Date: Thu, 29 Oct 2015 15:31:59 -0700 Subject: ASoC: rt5677: use 'active low' logic for reset pin According to the datasheet RESET is active low pin, i.e. system goes to reset state when pin signal is low. The previous implementeation was assuming the pin is configured as 'active high' in DTS. Changle the gpio handling code and DTS configuration to 'active low'.
