Merge tag 'devicetree-for-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull DeviceTree updates from Rob Herring: - remove most of_platform_populate() calls in arch code. Now the DT core code calls it in the default case and platforms only need to call it if they have special needs - use pr_fmt on all the DT core print statements - CoreSight binding doc improvements to block name descriptions - add dt_to_config script which can parse dts files and list corresponding kernel config options - fix memory leak hit with a PowerMac DT - correct a bunch of STMicro compatible strings to use the correct vendor prefix - fix DA9052 PMIC binding doc to match what is actually used in dts files * tag 'devicetree-for-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (35 commits) documentation: da9052: Update regulator bindings names to match DA9052/53 DTS expectations xtensa: Partially Revert "xtensa: Remove unnecessary of_platform_populate with default match table" xtensa: Fix build error due to missing include file MIPS: ath79: Add missing include file Fix spelling errors in Documentation/devicetree ARM: dts: fix STMicroelectronics compatible strings powerpc/dts: fix STMicroelectronics compatible strings Documentation: dt: i2c: use correct STMicroelectronics vendor prefix scripts/dtc: dt_to_config - kernel config options for a devicetree of: fdt: mark unflattened tree as detached of: overlay: add resolver error prints coresight: document binding acronyms Documentation/devicetree: document cavium-pip rx-delay/tx-delay properties of: use pr_fmt prefix for all console printing of/irq: Mark initialised interrupt controllers as populated of: fix memory leak related to safe_name() Revert "of/platform: export of_default_bus_match_table" of: unittest: use of_platform_default_populate() to populate default bus memory: omap-gpmc: use of_platform_default_populate() to populate default bus bus: uniphier-system-bus: use of_platform_default_populate() to populate default bus ...
