From b1b8f45b3130dbd8704e5ea0d82b49b1d929498e Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Sat, 21 Apr 2018 13:28:35 +0200 Subject: [PATCH] ARM: dts: bcm2837: Add missing GPIOs of Expander After commit a98d90e7d588 ("gpio: raspberrypi-exp: Driver for RPi3 GPIO expander via mailbox service") we are able to control the rest of the GPIOs of the RPi 3. So add all the missing parts (ACT LED, Wifi & BT control, HDMI detect) to the DT.
