The ChromeOS EC implements a UCSI PPM. This driver is being developed in drivers/platform/chrome since 1) Most other drivers which depend on ChromeOS EC reside there. 2) Our architecture might undergo a few revisions rapidly, so platform/chrome seems like a good place while we finalize our design. This patch series creates a public include/usb/ucsi.h that can be used by transport drivers outside drivers/usb/typec/ucsi. Then, we use this interface and ChromeOS EC host commands to send UCSI commands in drivers/platform/chrome/cros_ec_ucsi.c.
