2013-03-18ARM: shmobile: Make sh73a0 INTC irqpin platform data staticMagnus Damm1-4/+4
The platform data for the INTC irq pin driver seems to be global symbols, make it static to allow multi-soc build. Signed-off-by: Magnus Damm <[email protected]> Signed-off-by: Simon Horman <[email protected]>
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.

2013-03-18ARM: shmobile: INTC External IRQ pin driver on sh73a0Magnus Damm5-127/+137
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.
