10 - Sebastian Reichel <sre@kernel.org>
13 The devicetree battery node provides static battery characteristics.
14 In smart batteries, these are typically stored in non-volatile memory
15 on a fuel gauge chip. The battery node should be used where there is
16 no appropriate non-volatile memory, or it is unprogrammed/incorrect.
