Merge tag 'drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM soc driver specific changes from Olof Johansson: - A long-coming conversion of various platforms to a common LED infrastructure - AT91 is moved over to use the newer MCI driver for MMC - Pincontrol conversions for samsung platforms - DT bindings for gscaler on samsung - i2c driver fixes for tegra, acked by i2c maintainer Fix up conflicts as per Olof. * tag 'drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (48 commits) drivers: bus: omap_l3: use resources instead of hardcoded irqs pinctrl: exynos: Fix wakeup IRQ domain registration check pinctrl: samsung: Uninline samsung_pinctrl_get_soc_data pinctrl: exynos: Correct the detection of wakeup-eint node pinctrl: exynos: Mark exynos_irq_demux_eint as inline pinctrl: exynos: Handle only unmasked wakeup interrupts pinctrl: exynos: Fix typos in gpio/wkup _irq_mask pinctrl: exynos: Set pin function to EINT in irq_set_type of GPIO EINTa drivers: bus: Move the OMAP interconnect driver to drivers/bus/ i2c: tegra: dynamically control fast clk i2c: tegra: I2_M_NOSTART functionality not supported in Tegra20 ARM: tegra: clock: remove unused clock entry for i2c ARM: tegra: clock: add connection name in i2c clock entry i2c: tegra: pass proper name for getting clock ARM: tegra: clock: add i2c fast clock entry in clock table ARM: EXYNOS: Adds G-Scaler device from Device Tree ARM: EXYNOS: Add clock support for G-Scaler ARM: EXYNOS: Enable pinctrl driver support for EXYNOS4 device tree enabled platform ARM: dts: Add pinctrl node entries for SAMSUNG EXYNOS4210 SoC ARM: EXYNOS: skip wakeup interrupt setup if pinctrl driver is used ...

- * LART uses the LED as follows:
- * - GPIO23 is the LED, on if system is not idle
- * You can use both CONFIG_LEDS_CPU and CONFIG_LEDS_TIMER at the same
- * time, but in that case the timer events will still dictate the
- * pace of the LED.
