From 14f0413ce3c400a74213a861bc8f47dca5e4d231 Mon Sep 17 00:00:00 2001 From: Howard Mitchell Date: Mon, 23 Mar 2015 21:17:01 +0000 Subject: ASoC: pcm512x: Remove hardcoding of pll-lock to GPIO4 Currently GPIO4 is hardcoded to output the pll-lock signal. Unfortunately this is after the pll-out GPIO is configured which is selectable in the device tree. Therefore it is not possible to use GPIO4 for pll-out. Therefore this patch removes the configuration of GPIO4.
