STM32G0 provides an integrated USB Type-C and power delivery interface [1]. It can be programmed with a firmware [2] to act as a PPM. Currently it implements UCSI protocol over I2C interface. A GPIO is used as an interrupt line.
This series adds a driver to support it, including: - dt-bindings documentation - optional STM32G0 firmware control and update, over a secondary I2C address - power management
