Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: "We've been sitting on this longer than we meant to due to travel and other activities, but the number of patches is luckily not that high. Biggest changes are from a batch of OMAP bugfixes, but there are a few for the broader set of SoCs too (bcm2835, pxa, highbank, tegra, at91 and i.MX). The OMAP patches contain some fixes for MUSB/PHY on omap4 which ends up being a bit on the large side but needed for legacy (non-DT) platforms. Beyond that there are a handful of hwmod/pm changes. So, fairly noncontroversial stuff all in all, and as usual around this time the fixes are well targeted at specific problems." * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: imx: ehci: fix host power mask bit ARM i.MX: fix error-valued pointer dereference in clk_register_gate2() ARM: at91/usbh: fix overcurrent gpio setup ARM: at91/AT91SAM9G45: fix crypto peripherals irq issue due to sparse irq support ARM: boot: Fix usage of kecho ARM: OMAP: ocp2scp: create omap device for ocp2scp ARM: OMAP4: add _dev_attr_ to ocp2scp for representing usb_phy drivers: bus: ocp2scp: add pdata support irqchip: irq-bcm2835: Add terminating entry for of_device_id table ARM: highbank: retry wfi on reset request ARM: OMAP4: PM: fix regulator name for VDD_MPU ARM: OMAP4: hwmod data: do not enable or reset the McPDM during kernel init ARM: OMAP2+: hwmod: add flag to prevent hwmod code from touching IP block during init ARM: dt: tegra: fix length of pad control and mux registers ARM: OMAP: hwmod: wait for sysreset complete after enabling hwmod ARM: OMAP2+: clockdomain: Fix OMAP4 ISS clk domain to support only SWSUP ARM: pxa/spitz_pm: Fix hang when resuming from STR ARM: pxa: hx4700: Fix backlight PWM device number ARM: OMAP2+: PM: add missing newline to VC warning message
