Usermode UCSI PPM implementation for evaluation and testing usage. Try using this with the ucsi_um_test kernel driver.
For usermode implementations, we use libi2c and libgpiod to provide an smbus implementation. You will need the right libraries to build:
sudo apt-get install libi2c-dev libgpiod-dev

The usermode ppm implementation consists of the PPM task, the PD driver and the I2C driver backing it. The OPM will either be a CLI (for locally triggering some functionality) or the ucsi_um_test kernel module.
