interrupt_controller: gic: Add support for the GIC400 The GIC400 is a common interrupt controller that can be used with the Cortex A and R series processors. This patch adds basic interrupt handling for the GIC, but does not handle multiple routing or priorities. Signed-off-by: Bradley Bolen <bbolen@lexmark.com>

scripts: dts: Simplify and improve 'compatible' matching Instead of properties: compatible: constraint: "foo" , just have compatible: "foo" at the top level of the binding. For backwards compatibility, the old 'properties: compatible: ...' form is still accepted for now, and is treated the same as a single-element 'compatible:'. The old syntax was inspired by dt-schema (though it isn't dt-schema-compatible), which is in turn a thin wrapper around json-schema (the idea is to transform .dts files into YAML and then verify them). Maybe the idea was to gradually switch the syntax over to dt-schema and then be able to use unmodified dt-schema bindings, but dt-schema is really a different kind of tool (a completely standalone linter), and works very differently from our stuff (see schemas/dt-core.yaml in the dt-schema repo to get an idea of just how differently). Better to keep it simple. This commit also piggybacks some clarifications to the binding template re. '#cells:'. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

dts: bindings: interrupt-controller: GIC: Update description When the GIC driver was originally introduced, it was only used on Cortex-R SoCs. However, this is not the case anymore. Update the description to reflect that this driver is not specific to Cortex-R. Signed-off-by: Piotr Wojnarowski <pwojnarowski@antmicro.com>

scripts: dts: Generalize '#cells' to allow multiple sources Implement a nice generalization suggested by Bobby Noelte. Instead of having a generic #cells key in bindings, have source-specific *-cells keys. Some examples: interrupt-cells: - irq - priority - flags gpio-cells: - pin - flags pwm-cells: - channel - period This makes bindings a bit easier to read, and allows a node to be a controller for many different 'phandle-array' properties. The prefix before *-cells is derived from the property name, meaning there's no fixed set of *-cells keys. This is possible because of the earlier 'phandle-array' generalization. The older #cells key is supported for backwards compatibility, but generates a deprecation warning. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

interrupt-cells:
interrupt_controller: gic: Support PPIs The GIC-400 driver currently only supports SPIs because the (32) offset for the INTIDs is hard-coded in the driver. At the driver level there is no really difference between PPIs and SPIs so we can easily extend the driver to support PPIs as well. This is useful if we want to add support for the ARM Generic Timers that use INTIDs in the PPI range. SPI interrupts are in the range [0-987]. PPI interrupts are in the range [0-15]. This commit adds interrupt 'type' cell to the GIC device tree binding and changes the 'irq' cell to use interrupt type-specific index, rather than a linear IRQ number. The 'type'+'irq (index)' combo is automatically fixed up into a linear IRQ number by the scripts/dts/gen_defines.py script.
