+ This is a part of device tree bindings for the MAX77759 companion Power
+ Management IC for USB Type-C applications.
+
+ The MAX77759 includes Battery Charger, Fuel Gauge, temperature sensors, USB
+ Type-C Port Controller (TCPC), NVMEM, and a GPIO expander.

The Maxim MAX77759 is a companion PMIC for USB Type-C applications and includes Battery Charger, Fuel Gauge, temperature sensors, USB Type-C Port Controller (TCPC), NVMEM, and a GPIO expander. This describes the top-level device. Signed-off-by: André Draszik <andre.draszik@linaro.org> --- v2: * rename expected nvmem subdev nodename to 'nvmem-0' I'd have preferred just 'nvmem', but that matches nvmem-consumer.yaml and fails validation. Note: MAINTAINERS doesn't need updating, the binding update for the first leaf device (gpio) adds a wildcard matching all max77759 bindings --- .../devicetree/bindings/mfd/maxim,max77759.yaml | 104 +++++++++++++++++++++ 1 file changed, 104 insertions(+)
