Add comprehensive PMBus driver for LTM4700 dual-channel regulator family. Includes support for device identification (LTM4700/LTM4777 variants), dual-channel monitoring, and complete LINEAR format conversion. Key features: - PMBus 1.3 compliant I2C interface (400kHz) - Dual-channel 50A per channel or single 100A operation - LINEAR11/LINEAR16 data format support - Device variant detection via MFR_SPECIAL_ID - Comprehensive status monitoring - Complete telemetry reading (VIN, IIN, VOUT, IOUT, temperatures) - Peak value tracking and management - NVM operations for configuration storage Signed-off-by: $(git config user.name) <$(git config user.email)>
Add comprehensive Industrial I/O (IIO) framework integration for LTM4700 dual-channel regulator with real-time telemetry and control interface. Key features: - 13 IIO channels covering all telemetry (VIN, IIN, VOUT0/1, IOUT0/1, etc.) - Real-time voltage/current/power/temperature monitoring - Write support for VOUT control and operation mode - Device identification and variant detection via IIO - Peak value management and fault clearing - Engineering unit conversion (mV, mA, m°C, mW) - Multi-channel configuration support - Complete Linux IIO subsystem compliance IIO Channels: - Input: VIN, IIN, PIN, IC temperature - Output: VOUT0/1, IOUT0/1, POUT0/1, external temperatures - Control: Operation mode, voltage commands, margins - Frequency: Per-channel switching frequency monitoring Signed-off-by: $(git config user.name) <$(git config user.email)>
