Subject: [PATCH 2/2] ARM: dts: brcmstb: add IRQ0 controller
Date: Wed, 18 Mar 2015 17:31:32 -0700 [thread overview]
Message-ID: <1426725092-16392-2-git-send-email-computersforpeace@gmail.com> (raw)
In-Reply-To: <1426725092-16392-1-git-send-email-computersforpeace@gmail.com>
This L2 controller handles multiplexing a few different interrupts. We
also need it for configuring the interrupt forwarding masks for the
UART.
With this, we can *now* boot BCM7445 to a prompt using the upstream
kernel + DTB.
