Subject[PATCH v2 0/4] usb: typec: ucsi: add support for stm32g0
Date
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

[2] https://github.com/STMicroelectronics/x-cube-ucsi

Changes in v2:
- Krzysztof's review comments on dt-bindings: update commit message, use ports,
use unevaluatedProperties: false for usb-connector schema, define maxItems
for power-domains, adopt generic node names, remove quotes.
- Christophe's comments on driver:
use kmalloc instead of kzalloc
Use-after-free of buf: directly print the offset
