The Tegra210 AGIC interrupt controller is a 2nd level interrupt controller located in a separate power domain to the main GIC interrupt controller. It can route interrupts to the main CPU cluster or an Audio DSP slave. This series only support routing interrupts to the main CPU cluster. Ideally we would like to re-use the existing ARM GIC driver because the AGIC is a GIC-400. However, in order to do so this requires adding runtime power management support for irqchips and several significant changes to the exisiting GIC driver for power management reasons. Changes since V1: - Updated GIC to only WARN and not return an error if configuring a PPI fails but will still return an error if an SPI fails (per discussion with Marc). - Dropped change to mask sense bits for GIC-v3 (as this is not necessary) - Split patch to avoid setting interrupt type when mapping the IRQ into two patches per TGLX's feedback. - Changed name of irqchip device structure to "parent_device" - Moved call to irq_chip_pm_get() outside of chip_bus_lock(). - Dropped patch to remove clock names from GIC DT documentation and added AGIC clock names. - Update GIC platform driver to look-up clocks names from static list.
