Add device tree binding for the board (micro)controller on Ten64 family boards[1]. The schema is simple and is (presently) only consumed by U-Boot, but it is possible nvmem, watchdog and other features could be described in the future, as well as extension to future Traverse boards.

dt-bindings: mfd: Move embedded controllers to own directory

2025-10-01T09:28:27+00:00

Move several embedded controller bindings (like ChromeOS EC, Gateworks System Controller and Kontron sl28cpld Board Management) to new subdirectory "embedded-controller" matching their purpose. An embedded controller (EC) is a discrete component that contains a microcontroller (i.e. a small CPU running a small firmware without operating system) mounted into a larger computer system running a fully fledged operating system that needs to utilize the embedded controller as part of its operation. So far the EC bindings were split between "mfd" and "platform" directory. MFD name comes from Linux, not hardware, and "platform" is a bit too generic. Rename Gateworks GSC and Huawei Gaokun filenames to match compatible, as preferred for bindings.
