Re: [PATCH v11 01/10] devicetree: power: Add battery.txt

From: Liam Breck <redacted>

Documentation of static battery characteristics that can be defined
for batteries which cannot self-identify. This information is required
by fuel-gauge and charger chips for proper handling of the battery.

+Battery Characteristics
+
+The devicetree battery node provides static battery characteristics. 
+In smart batteries, these are typically stored in non-volatile memory 
+on a fuel gauge chip. The battery node should be used where there is 
+no appropriate non-volatile memory, or it is unprogrammed/incorrect.
+
+Required Properties:
+ - compatible: Must be "simple-battery"
+
+Optional Properties:
+ - voltage-min-design-microvolt: drained battery voltage
+ - energy-full-design-microwatt-hours: battery design energy
+ - charge-full-design-microamp-hours: battery design capacity
+
+Battery properties are named, where possible, for the corresponding 
+elements in enum power_supply_property, defined in
+https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/linux/power_supply.h#n86
