2012-11-05ARM: tegra: move iomap.h to mach-tegraStephen Warren1-2/+1
Nothing outside mach-tegra uses this file, so there's no need for it to be in <mach/>. Since uncompress.h and debug-macro.S remain in include/mach, they need to include "../../iomap.h" becaue of this change. uncompress.h will soon be deleted in later multi-platform/single-zImage patches. debug-macro.S will need to continue to include this header using an explicit relative path, to avoid duplicating the physical->virtual address mapping that iomap.h dictates.

2012-02-06ARM: tegra: add support for tegra30 interruptsPeter De Schrijver1-4/+16
Tegra30 has 1 extra legacy interrupt controller. Use the GIC ITLinesNumber field to determine how many interrupt controllers we have and initialize appropriately. Also make room for the extra tegra30 interrupts by moving the GPIO IRQ base. This shouldn't affect existing code as it determines the correct IRQ number for GPIOs using TEGRA_GPIO_TO_IRQ().

2011-12-08arm/tegra: convert tegra20 to GIC devicetree bindingpdeschrijver@nvidia.com1-2/+8
Convert tegra20 IRQ intialization to the GIC devicetree binding. Modify the interrupt definitions in the dts files according to Documentation/devicetree/bindings/arm/gic.txt v3 (swarren): * Moved of_irq_init() call into board-dt.c to avoid ifdef'ing it. - Even with a dummy replacement if !CONFIG_OF, the reference from tegra_dt_irq_match[] to gic_of_init() would still have to be ifdef'd - It's plausible that tegra_dt_irq_match[] may need to contain more entries in the future, and defining what they are seems more suitable for board-dt.c than irq.c v2 (swarren): * Removed some stale GIC init code from board-dt.c * Undid some accidental 0x -> 0x0 search/replace.

2011-05-11ARM: tegra: irq: Move legacy_irq.c into irq.cColin Cross1-12/+65
