2013-04-02ARM: shmobile: sh73a0: add irqpin DT nodesGuennadi Liakhovetski1-0/+81
Add DT nodes for the 4 irqpin interrupt controllers on sh73a0. We add them to sh73a0.dtsi, which is also used by configurations, doing all their device instantiation from board the .c code. We rely on the fact, that such configurations don't instantiate devices from the device-tree.

2013-04-02ARM: shmobile: sh73a0: wait for completion when kicking the clockGuennadi Liakhovetski1-6/+17
To reconfigure clocks, controlled by FRQCRA and FRQCRB, a kick bit has to be set and to make sure the setting has taken effect, it has to be read back repeatedly until it is cleared by the hardware.

2013-04-02Merge tag 'renesas-intc-external-irq2-for-v3.10' into soc-baseSimon Horman14-128/+1115
Update for Renesas INTC External IRQ pin driver for v3.10 This adds support for shared interrupt lines to the Renesas INTC External IRQ pin driver which has already been queued up for v3.10 (tag renesas-intc-external-irq-for-v3.10). The patch "irqchip: intc-irqpin: Add support for shared interrupt lines" in renesas-intc-external-irq2-for-v3.10 is a dependency for "ARM: shmobile: r8a7740: Migrate from INTC to GIC". That dependency is the reason for this merge.
2013-03-28irqchip: intc-irqpin: Add support for shared interrupt linesBastian Hecht1-7/+83
On some hardware we don't have a 1-1 mapping from the external interrupts coming from INTC to the GIC SPI pins. We can however share lines to demux incoming IRQs on these SoCs. This patch enables the intc_irqpin driver to detect requests for shared interrupt lines and demuxes them properly by querying the INTC INTREQx0A registers. If you need multiple shared intc_irqpin device instances, be sure to mask out all interrupts on the INTC that share the one line before you start to register them. Else you run into IRQ floods that would be caused by interrupts for which no handler has been set up yet when the first intc_irqpin device is registered.

2013-03-18irqchip: Renesas IRQC driverMagnus Damm4-0/+330
This patch adds a driver for external IRQ pins connected to the IRQC hardware block on recent SoCs from Renesas. The IRQC hardware block is used together with more recent ARM based SoCs using the GIC. As usual the GIC requires external IRQ trigger setup somewhere else which in this particular case happens to be IRQC. This driver implements the glue code needed to configure IRQ trigger and also handle mask/unmask and demux of external IRQ pins hooked up from the IRQC to the GIC. Tested on r8a73a4 but is designed to work with a wide range of SoCs. The driver requires one GIC SPI per external IRQ pin to operate. Each driver instance will handle up to 32 external IRQ pins. The SoCs using this driver are currently mainly used together with regular platform devices so this driver allows configuration via platform data to support things like static interrupt base address. DT support will be added incrementally in the not so distant future.

2013-03-18ARM: shmobile: INTC External IRQ pin driver on r8a7779Magnus Damm3-1/+54
Update the r8a7779 IRQ code to make use of the INTC External IRQ pin driver for external interrupt pins IRQ0 -> IRQ3. The r8a7779 SoC can like older SH SoCs configure to use the IRQ0 -> IRQ3 signals as individual interrupts or a combined IRL mode. Without this patch the r8a7779 SoC code does not fully support external IRQ pins in individual IRQ mode. The r8a7779 PFC code does not yet have gpio_to_irq() support so no need to update such code. At this point the DT reference implementations are not covered. In the future such code shall tie in the INTC External IRQ pin driver via DT, so this kind of verbose code is not needed for the long term DT case.

Adjust the sh73a0 IRQ code to make use of the INTC External IRQ pin driver for external interrupt pins IRQ0 -> IRQ31. This removes quite a bit of special-case code in intc-sh73a0.c but the number of lines get replaced with platform device information in setup-sh73a0.c. The PFC code is also adjusted to make gpio_to_irq() return the correct interrupt number. At this point the DT reference implementations are not covered. In the future such code shall tie in the INTC External IRQ pin driver via DT, so this kind of verbose code is not needed for the long term DT case.

2013-03-18irqchip: Renesas INTC External IRQ pin driverMagnus Damm4-0/+479
This patch adds a driver for external IRQ pins connected to the INTC block on recent SoCs from Renesas. The INTC hardware block usually contains a rather wide range of features ranging from external IRQ pin handling to legacy interrupt controller support. On older SoCs the INTC is used as a general purpose interrupt controller both for external IRQ pins and on-chip devices. On more recent ARM based SoCs with Cortex-A9 the main interrupt controller is the GIC, but IRQ trigger setup still need to happen in the INTC hardware block. This driver implements the glue code needed to configure IRQ trigger and also handle mask/unmask and demux of external IRQ pins hooked up from the INTC to the GIC. Tested on sh73a0 and r8a7779. The hardware varies quite a bit with SoC model, for instance register width and bitfield widths vary wildly. The driver requires one GIC SPI per external IRQ pin to operate. Each driver instance will handle up to 8 external IRQ pins. The SoCs using this driver are currently mainly used together with regular platform devices so this driver allows configuration via platform data to support things like static interrupt base address. DT support will be added incrementally in the not so distant future.
