Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform changes from Olof Johansson: "New and updated SoC support. Also included are some cleanups where the platform maintainers hadn't separated cleanups from new developent in separate branches. Some of the larger things worth pointing out: - A large set of changes from Alexandre Belloni and Nicolas Ferre preparing at91 platforms for multiplatform and cleaning up quite a bit in the process. - Removal of CSR's "Marco" SoC platform that never made it out to the market. We love seeing these since it means the vendor published support before product was out, which is exactly what we want! New platforms this release are: - Conexant Digicolor (CX92755 SoC) - Hisilicon HiP01 SoC - CSR/sirf Atlas7 SoC - ST STiH418 SoC - Common code changes for Nvidia Tegra132 (64-bit SoC) We're seeing more and more platforms having a harder time labelling changes as cleanups vs new development -- which is a good sign that we've come quite far on the cleanup effort. So over time we might start combining the cleanup and new-development branches more" * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (124 commits) 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: digicolor: select syscon and timer ARM: zynq: Simplify SLCR initialization ARM: zynq: PM: Fixed simple typo.
