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 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEcBAABAgAGBQJUz8xZAAoJEAf03oE53VmQMXsH/20+t69ZaB7HHVkyJpqtHs4e ilGPL+hSxofFjzfdvr1baHyUI6Jdu4pUHxBOBw8IY0PF87cbVhdn8JcD9eb5nnBD Z/ekKwZFnKXOyfQaRC1CHad7T+u6wa2uY+4LOC92JZipglltBVBPrm9wjfPIkii7 R13AeXNi4a3DiOXhsAevbeLNeKF/X7L52RfVPttJwfih9B1YpSmetkMjE+mpk9D9 P1JGhgTJyojhU2AacaRA3ECut8gWqBBN/FcswAZd5POxcBbNkDlZwCgXTGf3JXEt deVd8Sud/bCbzbxhHMGDvGmMluLpBCoxmy0ArDRewauDv6K4AbnO1p29Ad9Vs/U= =ESBq -----END PGP SIGNATURE----- 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 Signed-off-by: Olof Johansson <olof@lixom.net>
