Add device tree binding documentation for the Analog Devices LTC4284 High Power Negative Voltage Hot Swap Controller with Energy Monitor. The LTC4284 is designed for high power negative voltage hot swap applications, primarily in -48V distributed power systems, supporting up to 2500W applications with dual-gate operation modes, comprehensive voltage/current/power monitoring, and advanced protection features. Key features supported in binding: - Dual current sense resistor configuration - Configurable operation modes (single, parallel, staged start) - Voltage mode selection for various input ranges - Current limit and protection settings - Fault logging and retry configuration Signed-off-by: Carlos Jones <carlosjr.jones@analog.com>

Add driver for Analog Devices LTC4284 High Power Negative Voltage Hot Swap Controller with Energy Monitor. The LTC4284 is a high power hot swap controller designed for -48V distributed power systems supporting up to 2500W applications. It features dual-gate MOSFET drivers with multiple operation modes, comprehensive monitoring capabilities, and advanced protection. Key features: - Dual current sensing with independent sense resistors - Voltage, current, power, and energy monitoring - Four operation modes: single, parallel, staged start (high/low stress) - Programmable current limiting (15mV-30mV sense voltage range) - Min/max history tracking with reset capability - Comprehensive fault detection and logging - I2C interface with regmap support The driver integrates with the hwmon subsystem providing standard sysfs interfaces for monitoring and configuration. Device tree properties allow configuration of sense resistors, operation modes, voltage ranges, and protection settings. Signed-off-by: Carlos Jones <carlosjr.jones@analog.com>
