From mboxrd@z Thu Jan 1 00:00:00 1970 From: wens@csie.org (Chen-Yu Tsai) Date: Sat, 27 Aug 2016 15:55:42 +0800 Subject: [PATCH v2 6/8] ARM: dts: sun9i: a80-optimus: Add AXP806 PMIC device node and regulators In-Reply-To: <20160827075544.26316-1-wens@csie.org> References: <20160827075544.26316-1-wens@csie.org> Message-ID: <20160827075544.26316-7-wens@csie.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The AXP806 PMIC is the secondary 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.
