Subject: [PATCH] ARM: dts: omap3-gta04: add pulldown/up settings for twl4030 gpio
Date: Mon, 24 Sep 2018 19:29:57 +0200	[thread overview]
Message-ID: <20180924172957.20366-1-andreas@kemnade.info> (raw)

Pullup and down settings were missing, so add them to avoid
floating pins and make headset detection working.
