Merge tag 'soc-part2-for-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc

Pull "part 2 of omap SoC changes" from Tony Lindgren:

Few hwmod changes to support upcoming 8250 driver with DMA,
start using the SRAM driver for some omaps, and update the
defconfig.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>

* tag 'soc-part2-for-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP4+: Remove static iotable mappings for SRAM
  ARM: OMAP4+: Move SRAM data to DT
  ARM: AM335x: Get rid of unused sram init function
  ARM: omap2plus_defconfig: Enable some display features
  ARM: omap2plus_defconfig: Enable battery and reset drivers
  ARM: omap2plus_defconfig: Add support for distros with systemd
  ARM: omap2plus_defconfig: Add cpufreq to defconfig
  ARM: omap2plus_defconfig: Shrink with savedefconfig
  ARM: OMAP3: Use manual idle for UARTs because of DMA errata
  ARM: OMAP2+: Add hwmod flag for HWMOD_RECONFIG_IO_CHAIN
