Update to ChibiOS 18.2.1
Another big ChibiOS update, this time to the first stable release in the 18.2.x series. This time a few pieces of API that the firmware and library used were renamed, so there were some changes that had to be made there. The build system is nicer now, as the included makefiles add paths to the necessary variables so the main Makefile is much less verbose in a few places.
This library implements a subset of the USB Power Delivery Specification, Revision 2.0, Version 1.3, and Revision 3.0, Version 1.1, for microcontrollers running ChibiOS and connected to an FUSB302B USB Power Delivery PHY.
The library’s API is not yet considered stable, and is not documented outside of source code comments. For an example of its use, see the PD Buddy Sink Firmware.
