This doesn't match the change. You're adding a whole new device binding. > Signed-off-by: Matheus Castello <matheus@castello.eng.br> > --- > .../power/supply/max17040_battery.txt | 33 +++++++++++++++++++ Part of an MFD?

For configure low level state of charge threshold alert signaled from max17040 we add "maxim,alert-low-soc-level" property.
