Merge tag 'devicetree-for-5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull Devicetree updates from Rob Herring: - Fix a unittest failure on UML. Preparation for converting to kunit test framework. - Add annotations to dtx_diff output - Fix unittest reporting of expected error - Move DMA configuration for virtual devices into the driver that needs it (s5p-mfc) - Vendor prefixes for feiyang and techstar - Convert ARM GIC, GICv3, and L2x0 to DT schema - Add r8a7778/9 HSCIF serial bindings * tag 'devicetree-for-5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: of: unittest: unflatten device tree on UML when testing dt-bindings: Add vendor prefix for feiyang dt-bindings: Add vendor prefix for techstar dt-bindings: display: add missing semicolon in example of: mark early_init_dt_alloc_reserved_memory_arch static of: add dtc annotations functionality to dtx_diff of: unittest: add caution to function header comment of: unittest: remove report of expected error dt-bindings: interrupt-controller: Convert ARM GICv3 to json-schema dt-bindings: interrupt-controller: Convert ARM GIC to json-schema dt-bindings: arm: l2x0: Convert L2 cache to json-schema media: s5p-mfc: Fix memdev DMA configuration dt-bindings: serial: sh-sci: Document r8a7778/9 HSCIF bindings
