SoC updates for omaps for v4.14. Most of the chages are to add 

support for new dra762 SoC. The other changes are are for legacy
 DMA code removal, and MMC quirk and iodelay config for dra7.

Pull "soc changes for omaps for v4.14" from Tony Lindgren:

SoC updates for omaps for v4.14. Most of the chages are to add
support for new dra762 SoC. The other changes are are for legacy
DMA code removal, and MMC quirk and iodelay config for dra7.

* tag 'omap-for-v4.14/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP: dra7: powerdomain data: Register SoC specific powerdomains
  ARM: dra762: Enable SMP for dra762
  ARM: dra7: hwmod: Register dra76x specific hwmod
  ARM: dra762: Add support for device identification
  ARM: OMAP2+: board-generic: add support for dra762 family
  ARM: OMAP2+: Select PINCTRL_TI_IODELAY for SOC_DRA7XX
  ARM: OMAP2+: Add pdata-quirks for MMC/SD on DRA74x EVM
