There are both new drivers as well as existing drivers that are getting converted from platform-specific code into standalone drivers using the appropriate subsystem specific interfaces. In particular, we can now have pinctrl, clk, clksource and irqchip drivers in one file per driver, without the need to call into platform specific interface, or to get called from platform specific code, as long as all information about the hardware is provided through a device tree. Most of the drivers we touch this time are for clocksource. Since now most of them are part of drivers/clocksource, I expect that we won't have to touch these again from arm-soc and can let the clocksource maintainers take care of these in the future. Another larger part of this series is specific to the exynos platform, which is seeing some significant effort in upstreaming and modernization of its device drivers this time around, which unfortunately is also the cause for the churn and a lot of the merge conflicts. There is one new subsystem that gets merged as part of this series: the reset controller interface, which is a very simple interface for taking devices on the SoC out of reset or back into reset. Patches to use this interface on i.MX follow later in this merge window, and we are going to have other platforms (at least tegra and sirf) get converted in 3.11. This will let us get rid of platform specific callbacks in a number of platform independent device drivers." * tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (256 commits) irqchip: s3c24xx: add missing __init annotations ARM: dts: Disable the RTC by default on exynos5 clk: exynos5250: Fix parent clock for sclk_mmc{0,1,2,3} ARM: exynos: restore mach/regs-clock.h for exynos5 clocksource: exynos_mct: fix build error on non-DT pinctrl: vt8500: wmt: Fix checking return value of pinctrl_register() irqchip: vt8500: Convert arch-vt8500 to new irqchip infrastructure reset: NULL deref on allocation failure reset: Add reset controller API dt: describe base reset signal binding ARM: EXYNOS: Add arm-pmu DT binding for exynos421x ARM: EXYNOS: Add arm-pmu DT binding for exynos5250 ARM: EXYNOS: Enable PMUs for exynos4 irqchip: exynos-combiner: Correct combined IRQs for exynos4 irqchip: exynos-combiner: Add set_irq_affinity function for combiner_irq ARM: EXYNOS: fix compilation error introduced due to common clock migration clk: exynos5250: Fix divider values for sclk_mmc{0,1,2,3} clk: exynos4: export clocks required for fimc-is clk: samsung: Fix compilation error clk: tegra: fix enum tegra114_clk to match binding ...
* irqchip: s3c24xx: add missing __init annotationsArnd Bergmann2013-04-291-2/+2
| | | | | | | | | | | | | | | | The s3c24xx_init_intc and s3c2412_init_irq functions are only called at init time, and they call functions already marked __init, so they should be marked in the same way. This was reported as WARNING: vmlinux.o(.text+0x19e0b4): Section mismatch in reference from the function s3c2412_init_irq() to the function .init.text:s3c24xx_init_intc.constprop.8() The function s3c2412_init_irq() references the function __init s3c24xx_init_intc.constprop.8(). This is often because s3c2412_init_irq lacks a __init annotation or the annotation of s3c24xx_init_intc.constprop.8 is wrong.

* irqchip: s3c24xx: make interrupt handling independent of irq_domain structureHeiko Stuebner2013-04-041-10/+15
| | | | | | | | | | | | | | Keep a pointer to the corresponding s3c_irq_data struct as irq_chip_data. This removes the need to fetch the intc struct from the irq_domains host_data, thus making it independent of the underlying irq_domain structure. Also keep the real register offset of the interrupt in the s3c_irq_data struct to make it independent of the hwirq structure in the irq_domain Signed-off-by: Heiko Stuebner <heiko@sntech.de> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
* irqchip: s3c24xx: globally keep track of the created intc instancesHeiko Stuebner2013-04-041-49/+50
| | | | | | | | | | For dt-enabled machines we want to use a big irq_domain over all controllers and therefore need to access not only the main controllers but the sub-controller as well.

* irqchip: s3c24xx: fix irqlist of second s3c2416 controllerHeiko Stuebner2013-04-041-3/+2
| | | | | | | | | | | The list in used was from the s3c2450, a close cousin of the s3c2416. As it's not possible to distinguish between the s3c2416 and s3c2450 the additional interrupts of the s3c2450 will only be available thru devicetree later.
