Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM driver updates from Olof Johansson: "Updates of SoC-near drivers and other driver updates that makes more sense to take through our tree. The largest part of this is a conversion of device registration for some renesas shmobile/sh devices over to use resources. This has required coordination with the corresponding arch/sh changes, and we've agreed to merge the arch/sh changes through our tree. Added in this branch is support for Trusted Foundations secure firmware, which is what is used on many of the commercial Nvidia Tegra products that are in the market, including the Nvidia Shield. The code is local to arch/arm at this time since it's uncertain whether it will be shared with arm64 longer-term, if needed we will refactor later. A couple of new RTC drivers used on ARM boards, merged through our tree on request by the RTC maintainer. ... plus a bunch of smaller updates across the board, gpio conversions for davinci, etc" * tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (45 commits) watchdog: davinci: rename platform driver to davinci-wdt tty: serial: Limit msm_serial_hs driver to platforms that use it mmc: msm_sdcc: Limit driver to platforms that use it usb: phy: msm: Move mach dependent code to platform data clk: versatile: fixup IM-PD1 clock implementation clk: versatile: pass a name to ICST clock provider ARM: integrator: pass parent IRQ to the SIC irqchip: versatile FPGA: support cascaded interrupts from DT gpio: davinci: don't create irq_domain in case of unbanked irqs gpio: davinci: use chained_irq_enter/chained_irq_exit API gpio: davinci: add OF support gpio: davinci: remove unused variable intc_irq_num gpio: davinci: convert to use irqdomain support. gpio: introduce GPIO_DAVINCI kconfig option gpio: davinci: get rid of DAVINCI_N_GPIO gpio: davinci: use {readl|writel}_relaxed() instead of __raw_* serial: sh-sci: Add OF support serial: sh-sci: Add device tree bindings documentation serial: sh-sci: Remove platform data mapbase and irqs fields serial: sh-sci: Remove platform data scbrr_algo_id field ...
