Subject: [PATCH 3/9] ARM: dts: bcm2711: Add firmware usb reset node
Date: Mon,  8 Jun 2020 21:26:55 +0200	[thread overview]
Message-ID: <20200608192701.18355-4-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20200608192701.18355-1-nsaenzjulienne@suse.de>

Now that the reset driver exposing Raspberry Pi 4's firmware based USB
reset routine is available, let's add the device tree node exposing it.
