Subject: [PATCH 4.19 53/95] ARM: dts: bcm2835-rpi-zero-w: Fix led polarity

From: Vincent Stehlé <vincent.stehle@...oste.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].
