If an IRQ is pending on the processor at the time wfi is issued, the wfi instruction completes and the processor restarts execution without asserting the standbywfi signal. Depending on the platform power controller HW this behaviour can be acceptable or not; if this behaviour must be prevented software should be provided with a way to disable the routing of interrupts to the core IRQ pins. On systems where raw GIC distributor interrupts are connected to the power controller as wake-up events (hence the power controller still senses IRQs and can wake up cores upon IRQ pending), the GIC CPU interface can be disabled on power down, so that the GIC CPU IF output is gated and wfi cannot complete, thereby preventing the standbywfi issue. This patch adds a simple function to the GIC driver that allows to disable the GIC CPU IF from power down procedures.

The PDC has a number of general system wakeup (SysWake) interrupts (which would for example be connected to a power button or an external peripheral), and a number of peripheral interrupts which can also wake the system but are connected straight to specific low-power peripherals (such as RTC or Infrared). It has a single interrupt output for SysWakes, and individual interrupt outputs for each peripheral. The driver demuxes the SysWake interrupt line, and passes the peripheral interrupts straight through. It also handles the set_wake interrupt operation to enable/disable the appropriate wake event bits.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the series of patches for irqdomain core in 3.11 has broken sirf irq which uses legacy mapping. all users fail in the new kernel while setupping irq. this patch moves to linear irqdomain and drop old legacy irqdomain codes since we don't need it any more, and at the same time, it also fixes the broken interrupts of sirfsoc in 3.11. on the other hand, we actually only have 64 interrupt sources for prima2 and atlas6, but there are 128 interrupt souces for marco which uses GIC. in the legacy codes, sirf gpio also uses legacy irqdomain, so to make gpio interrupt mapping not depend on the prima2/atlas6/marco an use unified marco,we enlarge prima2/atlas6 interrupt number to 128. here we don't need this workaround any more as sirf gpio also moved to linear mode before. so we move SIRFSOC_NUM_IRQS back to 64 too.

* | clocksource+irqchip: delete __cpuinit usage from all related filesPaul Gortmaker2013-07-141-4/+4
|/ | | | | | | | | | | | | | | | | | | | | | | The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. This removes all the drivers/clocksource and drivers/irqchip uses of the __cpuinit macros from all C files.

The existing code assumes that 0x7f means no interrupt, but this value is an actually valid irq number, namely gpio bank 0's irq. This results in the driver not detecting when irq 0x7f is active which makes the machine effectively dead lock. This patch removes the interrupt poll loop and allows usage of gpio0 interrupt without an infinite loop.

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 ...

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.
