[PATCH 0/3] usb: typec: Implement UCSI driver for ChromeOS

[Pavan Holla]

We are developing a UCSI ChromeOS EC transport driver. 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.
