Tom Rini 6a042f830f Subtree merge tag 'v6.12-dts' of dts repo [1] into dts/upstream
[1] https://git.kernel.org/pub/scm/linux/kernel/git/devicetree/devicetree-rebasing.git

Based on what "git diff" suggests, rename a device tree for
imx8mm_venice_defconfig and imx8mp_venice_defconfig

description: |
Surface devices use a standardized embedded controller to let the
operating system interface with various hardware functions. The
specific functionalities are modeled as subdevices and matched on
five levels: domain, category, target, instance and function.
