Merge tag 'devicetree-for-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull DeviceTree updates from Rob Herring: "A fairly large (by DT standards) pull request this time with the majority being some overdue moving DT binding docs around to consolidate similar bindings. - DT binding doc consolidation moving similar bindings to common locations. The majority of these are display related which were scattered in video/, fb/, drm/, gpu/, and panel/ directories. - Add new config option, CONFIG_OF_ALL_DTBS, to enable building all dtbs in the tree for most arches with dts files (except powerpc for now). - OF_IRQ=n fixes for user enabled CONFIG_OF. - of_node_put ref counting fixes from Julia Lawall. - Common DT binding for wakeup-source and deprecation of all similar bindings. - DT binding for PXA LCD controller. - Allow ignoring failed PCI resource translations in order to ignore 64-bit addresses on non-LPAE 32-bit kernels. - Support setting the NUMA node from DT instead of only from parent device. - Couple of earlycon DT parsing fixes for address and options" * tag 'devicetree-for-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (45 commits) MAINTAINERS: update DT binding doc locations devicetree: add Sigma Designs vendor prefix of: simplify arch_find_n_match_cpu_physical_id() function Documentation: arm: Fixed typo in socfpga fpga mgr example Documentation: devicetree: fix reference to legacy wakeup properties Documentation: devicetree: standardize/consolidate on "wakeup-source" property drivers: of: removing assignment of 0 to static variable xtensa: enable building of all dtbs mips: enable building of all dtbs metag: enable building of all dtbs metag: use common make variables for dtb builds h8300: enable building of all dtbs arm64: enable building of all dtbs arm: enable building of all dtbs arc: enable building of all dtbs arc: use common make variables for dtb builds of: add config option to enable building of all dtbs of/fdt: fix error checking for earlycon address of/overlay: add missing of_node_put of/platform: add missing of_node_put ...

-The main purpose of this PHY driver is to enable the USB PHY reference clock

-an NOP PHY driver. Hence this node is referenced as both the usb2 and usb3
-phy node in the USB Glue layer driver node.

- optimizations for the devices that are always connected. e.g. modem.
- - dr_mode : dual role mode. Indicates the working mode for the PHY. Can be
- "host", "peripheral", or "otg". Defaults to "host" if not defined.
- host means this is a host controller
- peripheral means it is device controller

- contains the UTMI pad control registers common to all USB controllers.

-VBUS control (required for dr_mode == otg, optional for dr_mode == host):
- - vbus-supply: regulator for VBUS
