Subject[PATCH 4.14 40/77] ARM: dts: bcm2835-rpi-zero-w: Fix led polarity
Date
From: Vincent Stehlé <vincent.stehle@laposte.net>

[ Upstream commit 58bb90ab415562eededb932455046924e65df342 ]

The status "ACT" led on the Raspberry Pi Zero W is on when GPIO 47 is low.

This has been verified on a board and somewhat confirmed by both the GPIO
name ("STATUS_LED_N") and the reduced schematics [1].
