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 ...

+ Report driver source files that match the compatibles in the device
+ tree file and the kernel config options that enable the driver source
+ files.
+
+ This program must be run in the root directory of a Linux kernel
+ source tree.
+
+ The default format is a report that is intended to be easily human
+ scannable.
+
+ An alternate format can be selected by --config-format. This will
+ create output that can easily be edited to create a fragment that can
+ be appended to the existing kernel config file. Each entry consists of
+ multiple lines. The first line reports flags, the node path, compatible
+ value, driver file matching the compatible, configuration options, and
+ current values of the configuration options. For each configuration
+ option, the following lines report the current value and the value that
+ is required for the driver file to be included in the kernel.
+
+ If a large number of drivers or config options is listed for a node,
+ and the '$pr_flag_value[$pr_flag_pos_hard_coded]' flag is set consider using --white-list-config and/or
+ --white-list-driver. If the white list option suppresses the correct
+ entry please report that as a bug.
+
+ CAUTION:
+ This program uses heuristics to guess which driver(s) support each
+ compatible string and which config option(s) enables the driver(s).
+ Do not believe that the reported information is fully correct.
+ This program is intended to aid the process of determining the
+ proper kernel configuration for a device tree, but this is not
+ a fully automated process -- human involvement may still be
+ required!
+
+ The driver match heuristic used is to search for source files
+ containing the compatible string enclosed in quotes.
+
+ This program might not be able to find all drivers matching a
+ compatible string.
+
+ Some makefiles are overly clever. This program was not made
+ complex enough to handle them. If no config option is listed
+ for a driver, look at the makefile for the driver source file.
+ Even if a config option is listed for a driver, some other
+ available config options may not be listed.
