Subject: [PATCH 1/6] dt-bindings: mfd: add max77759 binding
Add device tree binding for the Maxim MAX77759 companion PMIC 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.
This describes the core mfd device.
