Maxim MAX77802 is a power management chip that contains 10 high efficiency Buck regulators, 32 Low-dropout (LDO) regulators used to power up application processors and peripherals, a 2-channel 32kHz clock outputs, a Real-Time-Clock (RTC) and a I2C interface to program the individual regulators, clocks outputs and the RTC. This patch adds support for MAX77802 to the MAX77686 driver and is based on a driver added to the Chrome OS kernel 3.8 by Simon Glass.
