Merge tag 'devicetree-fixes-for-6.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree fixes from Rob Herring:

 - Disable #address-cells/#size-cells warning on coreboot (Chromebooks)
   platforms

 - Add missing root #address-cells/#size-cells in default empty DT

 - Fix uninitialized variable in of_irq_parse_one()

 - Fix interrupt-map cell length check in of_irq_parse_imap_parent()

 - Fix refcount handling in __of_get_dma_parent()

 - Fix error path in of_parse_phandle_with_args_map()

 - Fix dma-ranges handling with flags cells

 - Drop explicit fw_devlink handling of 'interrupt-parent'

 - Fix "compression" typo in fixed-partitions binding

 - Unify "fsl,liodn" property type definitions
