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"

+EEPROMs (SPI) compatible with Atmel at25.
+
+Required properties:
+- compatible : "atmel,at25".
+- reg : chip select number
+- spi-max-frequency : max spi frequency to use
+- pagesize : size of the eeprom page
+- size : total eeprom size in bytes
+- address-width : number of address bits (one of 8, 16, or 24)
+
+Optional properties:
+- spi-cpha : SPI shifted clock phase, as per spi-bus bindings.
+- spi-cpol : SPI inverse clock polarity, as per spi-bus bindings.
+- read-only : this parameter-less property disables writes to the eeprom
+
+Obsolete legacy properties are can be used in place of "size", "pagesize",
+"address-width", and "read-only":
+- at25,byte-len : total eeprom size in bytes
+- at25,addr-mode : addr-mode flags, as defined in include/linux/spi/eeprom.h
+- at25,page-size : size of the eeprom page
+
+Additional compatible properties are also allowed.
+
+Example:
+	at25@0 {
+		compatible = "atmel,at25", "st,m95256";
+		reg = <0>
+		spi-max-frequency = <5000000>;
+		spi-cpha;
+		spi-cpol;
+
+		pagesize = <64>;
+		size = <32768>;
+		address-width = <16>;
+	};
