From 1c72060511a46eee7166e4e3f6de689850bf5bcc Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Tue, 6 Feb 2018 12:49:02 +0800 Subject: [PATCH] ARM: dts: sun8i: h3: add SY8113B regulator used by Orange Pi One board Orange Pi One board has a SY8113B regulator, which is controlled via GPIO and capable of outputing 1.1V when the PL6 GPIO is set to output 0 or 1.3V when the PL6 GPIO is set to input or output 1, and the output is the power supply of the ARM cores in H3 SoC. Add the device tree node of this regulator and set the cpu's cpu-supply property to it.
