Subject[PATCH 00/10] platform/chrome: cros_ec_typec: VDM support
Date
This series adds support for sending and receiving USB PD Vendor
Defined Messages (VDMs) between the Application Processor's Type-C
ports and connected peripherals.

Thir enables the Application processor to enter alternate modes and
process VDMs directly, instead of relying on state machines that exist
inside of co-processors like the ChromeOS Embedded Controller (EC).

Patch 1/10 reverts an incorrect EC header modification.
Patch 2/10 to 5/10 update headers and existing Type-C structs to
accommodate the VDM code.
Patch 6/10 and 7/10 prepare the Type-C driver to have more than 1 file.
Patch 8/10 to 10/10 introduce the VDM functionality.

Patch submissions suggestion (if approved):
- Even though Patch 1 touches drivers/mfd, it would be better to take
the entire series through the cbrome-platform branch, to avoid
cross-dependencies across maintainer trees.
