Detailed Description

NXP PF1550 family I2C register map, bit-field constants, and OTP keys.

Covers MC34PF1550*, MC32PF1550*, and the unprogrammed-OTP variant MC34PF1550A0EP used on Arduino Portenta H7 eval modules.

Register addresses follow the NXP PF1550 datasheet (Rev. 7, September 2021) Section 12 Register map:

12.1 Specific PMIC registers — base I2C offset 0x00 (DEVICE_ID, interrupts, regulators, power control).
12.2 Specific Charger registers — base I2C offset 0x80 (CHG_INT, VBUS_SNS, CHG_SNS …).

Per-bit details are intentionally kept compact here; consult docs/datasheet/PF1550-i2c-register-reference.md (auto-generated extract of Section 12) for the authoritative bit semantics.

Versioning: Driver version exposed via HF_PF1550_VERSION (see pf1550_version.h).
