From 76931ca6e1b934d3a798146ec6f7498df9276b71 Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Sun, 13 Oct 2019 12:53:23 +0200 Subject: [PATCH] ARM: dts: bcm2837-rpi-cm3: Avoid leds-gpio probing issue bcm2835-rpi.dtsi defines the behavior of the ACT LED, which is available on all Raspberry Pi boards. But there is no driver for this particual GPIO on CM3 in mainline yet, so this node was left incomplete without the actual GPIO definition. Since commit e3fe42ad074c ("gpio: Fix return value mismatch of function gpiod_get_from_of_node()") this causing probe issues of the leds-gpio driver for users of the CM3 dtsi file. leds-gpio: probe of leds failed with error -2 Until we have the necessary GPIO driver hide the ACT node for CM3 to avoid this.
