Merge tag 'soc-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC specific changes from Arnd Bergmann: "Lots of changes specific to one of the SoC families. Some that stick out are: - mach-qcom gains new features, most importantly SMP support for the newer chips (Stephen Boyd, Rohit Vaswani) - mvebu gains support for three new SoCs: Armada 375, 380 and 385 (Thomas Petazzoni and Free-electrons team) - SMP support for Rockchips (Heiko Stübner) - Lots of i.MX changes (Shawn Guo) - Added support for BCM5301x SoC (Hauke Mehrtens) - Multiplatform support for Marvell Kirkwood and Dove (Andrew Lunn and Sebastian Hesselbarth doing the final part of a long journey) - Unify davinci platforms and remove obsolete ones (Sekhar Nori, Arnd Bergmann)" * tag 'soc-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (126 commits) ARM: sunxi: Select HAVE_ARM_ARCH_TIMER ARM: cache-tauros2: remove ARMv6 code ARM: mvebu: don't select CONFIG_NEON ARM: davinci: fix DT booting with default defconfig ARM: configs: bcm_defconfig: enable bcm590xx regulator support ARM: davinci: remove tnetv107x support MAINTAINERS: Update ARM STi maintainers ARM: restrict BCM_KONA_UART to ARCH_BCM_MOBILE ARM: bcm21664: Add board support.

+The SAW2 is a wrapper around the Subsystem Power Manager (SPM) and the

+the PMIC. It can also be wired up to interact with other processors in the
+system, notifying them when a low power state is entered or exited.

+Rockchip SRAM for smp bringup:
+------------------------------
+
+Rockchip's smp-capable SoCs use the first part of the sram for the bringup
+of the cores. Once the core gets powered up it executes the code that is
+residing at the very beginning of the sram.

+declaration.

+ * ARM freq are one of below setpoints: 396MHz, 792MHz and 996MHz, since
+ * the clk APIs can NOT be called in idle thread(may cause kernel schedule
+ * as there is sleep function in PLL wait function), so here we just slow
+ * down ARM to below freq according to previous freq:
