Subject: [PATCH 08/11] ARM: dts: sun9i: a80-optimus: Add AXP809 PMIC device
 node and regulators
In-Reply-To: <1454408864-24112-1-git-send-email-wens@csie.org>
References: <1454408864-24112-1-git-send-email-wens@csie.org>
Message-ID: <1454408864-24112-9-git-send-email-wens@csie.org>
To: linux-arm-kernel@lists.infradead.org
List-Id: linux-arm-kernel.lists.infradead.org

The AXP809 PMIC is the primary PMIC. It provides various supply voltages
for the SoC and other peripherals. The PMIC's interrupt line is
connected to NMI pin of the SoC.
