2025-05-09mfd: max77759: Add Maxim MAX77759 core driverAndré Draszik
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. Fuel Gauge and TCPC have separate and independent I2C addresses, register maps, and interrupt lines and are therefore excluded from the MFD core device driver here. The GPIO and NVMEM interfaces are accessed via specific commands to the built-in microprocessor. This driver implements an API that client drivers can use for accessing those.
