Pull devicetree fixes from Rob Herring:

 - Disable kunit tests for arm64+ACPI

 - Fix refcount issue in kunit tests

 - Drop constraints on non-conformant 'interrupt-map' in fsl,ls-extirq

 - Drop type ref on 'msi-parent in fsl,qoriq-mc binding

 - Move elgin,jg10309-01 to its own binding from trivial-devices

* tag 'devicetree-fixes-for-6.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux:
