Pull devicetree updates from Rob Herring:
 "DT core:

   - Add support for handling multiple cells in "iommu-map" entries

   - Support only 1 entry in /reserved-memory "reg" entries. Support for
     more than 1 entry has been broken

   - Fix a UAF on alloc_reserved_mem_array() failure

   - Make "ibm,phandle" handling logic specific to PPC

   - Use memcpy() instead of strcpy() for known length strings

   - Ensure __of_find_n_match_cpu_property() handles malformed "reg"
     entries

   - Add various checks that expected strings are strings before
     accessing them

   - Drop redundant memset() when unflattening DT

  DT bindings:

   - Add a DTS style checker. Currently hooked up to dt_binding_check to
     check examples

   - Convert st,nomadik platform, ti,omap-dmm, and ti,irq-crossbar
     bindings to DT schema

   - Add Apple System Management Controller hwmon, Qualcomm Hamoa
     Embedded Controller, Qualcomm IPQ6018 PWM controller, fsl,mc1323,
     Samsung SOFEF01-M DDIC panel, Freescale i.MX53 Television Encoder,
     Samsung S2M series PMIC extcon, and MT6365 PMIC AuxADC schemas

   - Extend bindings for QCom Maili and Nord PDC, QCom Hali fastrpc,
     qcom,eliza-imem, qcom,oryon-1-5 CPU, and MT6365 Keys

   - Consolidate "sram" property definitions

   - Fix constraints on "nvmem" properties which only contain phandles
     and no arg cells

   - Another pass of fixing "phandle-array" constraints

   - Add Gira vendor prefix"
