Subject: [PATCH] ARM: dts: bcm2835-rpi-zero-w: Fix led polarity
Date: Sat, 18 Apr 2020 14:35:22 +0200 [thread overview]
Message-ID: <20200418123522.6390-1-vincent.stehle@laposte.net> (raw)
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].

Fixes: 2c7c040c73e9 ("ARM: dts: bcm2835: Add Raspberry Pi Zero W")
