From 8c51c65273628a3da3c18b258cecb27835e52727 Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Mon, 26 Oct 2020 22:19:34 +0800 Subject: [PATCH] sunxi: allow to use AXP20[39] attached to I2C0 on V3 series The reference design of Allwinner V3 series uses an AXP203 or AXP209 PMIC attached to the I2C0 bus of the SoC, although the first community-available V3s board, Lichee Pi Zero, omitted it. Allow to introduce support for the PMIC on boards with it.
