This patch adds devicetree bindings documentation for battery charging controller as the subnode of MAX8998 PMIC.
Signed-off-by: Paweł Chmiel <[email protected]> --- Changes from v3: - Property prefix should be maxim, not max8998 - Describe what End of Charge in percent means Changes from v2: - Make charge-restart-level-microvolt optional. - Make charge-timeout-hours optional. Changes from v1: - Removed unneeded Fixes tag - Correct description of all charger values - Added missing property unit --- .../devicetree/bindings/mfd/max8998.txt | 26 +++++++++++++++++++ 1 file changed, 26 insertions(+) diff --git a/Documentation/devicetree/bindings/mfd/max8998.txt b/Documentation/devicetree/bindings/mfd/max8998.txt index 5f2f07c09c90..368f787d6079 100644 --- a/Documentation/devicetree/bindings/mfd/max8998.txt +++ b/Documentation/devicetree/bindings/mfd/max8998.txt @@ -48,6 +48,25 @@ Additional properties required if max8998,pmic-buck2-dvs-gpio is defined: - max8998,pmic-buck2-dvs-voltage: An array of 2 voltage values in microvolts for buck2 regulator that can be selected using dvs gpio. +Charger: Configuration for battery charging controller should be added +inside a child node named 'charger'. + Required properties: + - maxim,end-of-charge-percentage: End of Charge in percent. + When the charge current in constant-voltage phase drops below + end-of-charge-percentage of it's start value, charging is terminated. + If value equals 0, leave it unchanged.
