Detailed Description

Unified handler for MAX22200 octal solenoid and motor driver.

Provides HAL-level integration for the MAX22200 on shared SPI2 using BaseSpi and BaseGpio. Features:

• CRTP SPI adapter bridging BaseSpi to the MAX22200 two-phase CMD-pin SPI protocol (CMD HIGH = command byte, CMD LOW = data)
• 8-channel high/low-side output control with CDR/VDR drive modes
• Channel-pair modes (independent, parallel, half-bridge, full-bridge)
• Comprehensive fault monitoring and DPM (Detect Plunger Movement)
• Convenience APIs with real-unit parameters (mA, %, ms)
• Thread-safe operations with RtosMutex (WithDriver preferred)
• Lazy initialization pattern
• Raw driver access through GetDriver for single-threaded bring-up only

Note

Which channels are populated and with what part is defined by pw_hal/valve_hardware.hpp. Unpopulated channels keep their open-load detectors disabled so they cannot contribute OLF/OCP faults.
