  arm/dts: OMAP3: Add i2c controller nodes
  arm/dts: OMAP4: Add i2c controller nodes
  ARM: OMAP2+: Set Kconfig dependencies for PROC_DEVICETREE
  arm/dts: OMAP3&4: Remove the '0x' prefix for serial nodes
  ARM: OMAP1: kconfig: Enable IRQ_DOMAIN by default for OMAP1 platforms
  ARM: OMAP2+: pm: Do not init statically the SR and voltage layer with DT
  ARM: OMAP2+: omap_device: Replace dev_warn by dev_dbg in omap_device_build_from_dt
  ARM: OMAP2+: board-generic: Remove un-needed .atag_offset for DT_MACHINE
  ARM: OMAP2+: kconfig: Enable devicetree by default for OMAP2+ systems
  arm/dts: OMAP: Remove bootargs node from board files
