While there is currently no mainline driver for these binding, there is an open source out-of-tree kernel-side driver available[1]. Having a stable and upstream binding for these devices allows us to describe this hardware in device tree. This is my vision for how these bindings should look, along with some example uses in several SoC DT files. The compatible names have been updated to match what was decided on for Series6+, but otherwise most is the same as we have been using in our vendor tree for many years. Thanks, Andrew Based on next-20231204.
