From 31f0491da62061b90a1069cbec63b9e13cd9ee7f Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 24 May 2017 13:40:15 +0800 Subject: [PATCH] ARM: sun8i: a83t: cubietruck-plus: Enable PMIC part of AXP818 PMIC The AXP813/AXP818 PMICs used with the A83T/H8 SoCs are actually 2 dies in one package sharing the serial bus (I2C/RSB) pins. One die is the actual PMIC. The other is an AC100 codec / RTC combo chip. This patch enables the RSB controller and adds a device node for the PMIC die to the Cubietruck Plus device tree. Since the AXP813 and AXP818 are virtually identical, this patch uses the compatible string for the former as a fallback.
