Subject: [PATCH v2 2/5] dt-bindings: Document brcm,irq-can-wake for brcm,bcm7038-l1-intc.txt
Date: Fri, 13 Sep 2019 12:15:39 -0700 [thread overview]
Message-ID: <20190913191542.9908-3-f.fainelli@gmail.com> (raw)
In-Reply-To: <20190913191542.9908-1-f.fainelli@gmail.com>
The BCM7038 L1 interrupt controller can be used as a wake-up interrupt
controller on MIPS and ARM-based systems, document the brcm,irq-can-wake
which has been "standardized" across Broadcom interrupt controllers.
