Subject: [PATCH v2 1/9] dt-bindings: reset: Add a binding for the RPi Firmware reset controller
Date: Tue,  9 Jun 2020 19:49:54 +0200	[thread overview]
Message-ID: <20200609175003.19793-2-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20200609175003.19793-1-nsaenzjulienne@suse.de>

The firmware running on the RPi VideoCore can be used to reset and
initialize HW controlled by the firmware.

Signed-off-by: Nicolas Saenz Julienne <nsaenzjulienne@suse.de>
