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 ...

+LIS302 accelerometer devicetree bindings
+
+This device is matched via its bus drivers, and has a number of properties
+that apply in on the generic device (independent from the bus).
+
+
+Required properties for the SPI bindings:
+ - compatible: should be set to "st,lis3lv02d_spi"
+ - reg: the chipselect index
+ - spi-max-frequency: maximal bus speed, should be set to 1000000 unless
+ constrained by external circuitry
+ - interrupts: the interrupt generated by the device
+
+Required properties for the I2C bindings:
+ - compatible: should be set to "st,lis3lv02d"
+ - reg: i2c slave address
+ - Vdd-supply: The input supply for Vdd
+ - Vdd_IO-supply: The input supply for Vdd_IO
+
+
+Optional properties for all bus drivers:
+
+ - st,click-single-{x,y,z}: if present, tells the device to issue an
+ interrupt on single click events on the
+ x/y/z axis.
+ - st,click-double-{x,y,z}: if present, tells the device to issue an
+ interrupt on double click events on the
+ x/y/z axis.
+ - st,click-thresh-{x,y,z}: set the x/y/z axis threshold
+ - st,click-click-time-limit: click time limit, from 0 to 127.5msec
+ with step of 0.5 msec
+ - st,click-latency: click latency, from 0 to 255 msec with
+ step of 1 msec.
+ - st,click-window: click window, from 0 to 255 msec with
+ step of 1 msec.
+ - st,irq{1,2}-disable: disable IRQ 1/2
+ - st,irq{1,2}-ff-wu-1: raise IRQ 1/2 on FF_WU_1 condition
+ - st,irq{1,2}-ff-wu-2: raise IRQ 1/2 on FF_WU_2 condition
+ - st,irq{1,2}-data-ready: raise IRQ 1/2 on data ready contition
+ - st,irq{1,2}-click: raise IRQ 1/2 on click condition
+ - st,irq-open-drain: consider IRQ lines open-drain
+ - st,irq-active-low: make IRQ lines active low
+ - st,wu-duration-1: duration register for Free-Fall/Wake-Up
+ interrupt 1
+ - st,wu-duration-2: duration register for Free-Fall/Wake-Up
+ interrupt 2
+ - st,wakeup-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for
+ upper/lower limit
+ - st,wakeup-threshold: set wakeup threshold
+ - st,wakeup2-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for
+ upper/lower limit for second wakeup
+ engine.
+ - st,wakeup2-threshold: set wakeup threshold for second wakeup
+ engine.
+ - st,highpass-cutoff-hz=: 1, 2, 4 or 8 for 1Hz, 2Hz, 4Hz or 8Hz of
+ highpass cut-off frequency
+ - st,hipass{1,2}-disable: disable highpass 1/2.
+ - st,default-rate=: set the default rate
+ - st,axis-{x,y,z}=: set the axis to map to the three coordinates.
+ Negative values can be used for inverted axis.
+ - st,{min,max}-limit-{x,y,z} set the min/max limits for x/y/z axis
+ (used by self-test)
+
+
+Example for a SPI device node:
+
+ lis302@0 {
+ compatible = "st,lis302dl-spi";
+ reg = <0>;
+ spi-max-frequency = <1000000>;
+ interrupt-parent = <&gpio>;
+ interrupts = <104 0>;

+ st,wakeup-x-hi;
+ st,wakeup-y-lo;
+ st,wakeup-y-hi;
+ st,wakeup-z-lo;
+ st,wakeup-z-hi;
+ };
+
+Example for a I2C device node:
+
+ lis331dlh: lis331dlh@18 {

+ reg = <0x18>;
