From 6ddd5fce849a5d06bee7e5cf10ad7db21b68aa7b Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Mon, 24 Aug 2015 10:20:04 +0300 Subject: [PATCH] ARM: dts: dra72-evm: Add gpio hog for vin6_sel_s0 to select audio The GPIO expander's p1 on i2c5 bus 0x26 address is used for selecting between audio and VIN6 functionality. For VIN6 use an add on card is needed while audio is present on the board itself. Select the audio functionality over the VIN6 in the dts file.
