From 7221675c70d147f2ae6f044697dff046f3805224 Mon Sep 17 00:00:00 2001 From: Quentin Schulz Date: Tue, 18 Apr 2017 09:34:16 +0200 Subject: [PATCH] dt-bindings: power: supply: add AXP20X/AXP22X battery DT binding The X-Powers AXP20X and AXP22X PMICs can have a battery as power supply. This patch adds the DT binding documentation for the battery power supply which gets various data from the PMIC, such as the battery status (charging, discharging, full, dead), current max limit, current current, battery capacity (in percentage), voltage max and min limits, current voltage and battery capacity (in Ah).
