Merge tag 'at91-soc4' of git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91 into next/soc

Merge "at91: cleanup/soc for 3.20 #4" from Nicolas Ferre:

Fourth cleanup/soc batch for 3.20:
- merge all the at91sam9 code and remove the empty SoC-specific files
- remove the at91_boot_soc that is now useless in a DT context
- move the sram code in PM code as it's now only used there
- some file + function name changes after this big cleanup

* tag 'at91-soc4' of git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91:
  ARM: at91/trivial: unify functions and machine names
  ARM: at91: remove at91_dt_initialize and machine init_early()
  ARM: at91: change board files into SoC files
  ARM: at91: remove at91_boot_soc
  ARM: at91: move alternative initial mapping to board-dt-sama5.c
  ARM: at91: merge all SOC_AT91SAM9xxx
  ARM: at91: at91rm9200: set idle and restart from rm9200_dt_device_init()
  ARM: at91: board-dt-sama5: add phy_fixup to override NAND_Tree
  ARM: at91/dt: sam9263: Add missing clocks to lcdc node
  ARM: at91: sama5d3: dt: correct the sound route
  ARM: at91/dt: sama5d4: fix the timer reg length
