Merge tag 'devicetree-for-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull Devicetree updates from Rob Herring: "The biggest highlight here is the start of using json-schema for DT bindings. Being able to validate bindings has been discussed for years with little progress. - Initial support for DT bindings using json-schema language. This is the start of converting DT bindings from free-form text to a structured format. - Reworking of initrd address initialization. This moves to using the phys address instead of virt addr in the DT parsing code. This rework was motivated by CONFIG_DEV_BLK_INITRD causing unnecessary rebuilding of lots of files. - Fix stale phandle entries in phandle cache - DT overlay validation improvements. This exposed several memory leak bugs which have been fixed. - Use node name and device_type helper functions in DT code - Last remaining conversions to using %pOFn printk specifier instead of device_node.name directly - Create new common RTC binding doc and move all trivial RTC devices out of trivial-devices.txt. - New bindings for Freescale MAG3110 magnetometer, Cadence Sierra PHY, and Xen shared memory - Update dtc to upstream version v1.4.7-57-gf267e674d145" * tag 'devicetree-for-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (68 commits) of: __of_detach_node() - remove node from phandle cache of: of_node_get()/of_node_put() nodes held in phandle cache gpio-omap.txt: add reg and interrupts properties dt-bindings: mrvl,intc: fix a trivial typo dt-bindings: iio: magnetometer: add dt-bindings for freescale mag3110 dt-bindings: Convert trivial-devices.txt to json-schema dt-bindings: arm: mrvl: amend Browstone compatible string dt-bindings: arm: Convert Tegra board/soc bindings to json-schema dt-bindings: arm: Convert ZTE board/soc bindings to json-schema dt-bindings: arm: Add missing Xilinx boards dt-bindings: arm: Convert Xilinx board/soc bindings to json-schema dt-bindings: arm: Convert VIA board/soc bindings to json-schema dt-bindings: arm: Convert ST STi board/soc bindings to json-schema dt-bindings: arm: Convert SPEAr board/soc bindings to json-schema dt-bindings: arm: Convert CSR SiRF board/soc bindings to json-schema dt-bindings: arm: Convert QCom board/soc bindings to json-schema dt-bindings: arm: Convert TI nspire board/soc bindings to json-schema dt-bindings: arm: Convert TI davinci board/soc bindings to json-schema dt-bindings: arm: Convert Calxeda board/soc bindings to json-schema dt-bindings: arm: Convert Altera board/soc bindings to json-schema ...
