Merge tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson: "We've got a fairly large cleanup branch this time. The bulk of this is removal of non-DT platforms of several flavors: - Atmel at91 platforms go full-DT, with removal of remaining board-file based support - OMAP removes legacy board files for three more platforms - removal of non-DT mach-msm, newer Qualcomm platforms now live in mach-qcom - Freescale i.MX25 also removes non-DT platform support" Most of the rest of the changes here are fallout from the above, i.e. for example removal of drivers that now lack platforms, etc. * tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (58 commits) mmc: Remove msm_sdcc driver gpio: Remove gpio-msm-v1 driver ARM: Remove mach-msm and associated ARM architecture code ARM: shmobile: cpuidle: Remove the pointless default driver ARM: davinci: dm646x: Add interrupt resource for McASPs ARM: davinci: irqs: Correct McASP1 TX interrupt definition for DM646x ARM: davinci: dm646x: Clean up the McASP DMA resources ARM: davinci: devices-da8xx: Add support for McASP2 on da830 ARM: davinci: devices-da8xx: Clean up and correct the McASP device creation ARM: davinci: devices-da8xx: Add interrupt resource to McASP structs ARM: davinci: devices-da8xx: Add resource name for the McASP DMA request ARM: OMAP2+: Remove legacy support for omap3 TouchBook ARM: OMAP3: Remove legacy support for devkit8000 ARM: OMAP3: Remove legacy support for EMA-Tech Stalker board ARM: shmobile: Consolidate the pm code for R-Car Gen2 ARM: shmobile: r8a7791: Correct SYSCIER value ARM: shmobile: r8a7790: Correct SYSCIER value ARM: at91: remove old setup ARM: at91: sama5d4: remove useless map_io ARM: at91: sama5 use SoC detection infrastructure ...
