Most of NXP's contributions to Zephyr occur in the upstream repository at https://github.com/zephyrproject-rtos/zephyr . Zephyr support is enabled by boards, see the upstream supported boards for the latest list of boards. Each board has a board document, which includes a Supported Features table of all the features currently supported on that board. For example, this is the upstream FRDM-MCXN947 board page.
NXP also provides a downstream ecosystem called the Zephyr Software Developement Kit (ZSDK). Some devices/boards have additional support in the NXP ZSDK. To review the NXP ZSDK support, see the release notes. To learn more, see Introduction to ZSDK Downstream and ZSDK Getting Started.
