From f6b6631478d7708d86dc0b268671d5191b96946e Mon Sep 17 00:00:00 2001 From: Hans Verkuil <hverkuil@xs4all.nl> Date: Fri, 20 Apr 2018 04:13:53 -0400 Subject: [PATCH] media: cec-gpio: use GPIOD_OUT_HIGH_OPEN_DRAIN This driver needs a pull up output GPIO, but devm_gpiod_get() is called with GPIOD_IN. This apparently works fine for the RPi3 where the DT correctly specifies a pull up GPIO, but on the i.MX6 it also needs to be specified with devm_gpiod_get().
