Hi, This patch adds support for Microchip External Interrupt Controller present on SAMA7G5. The controller supports for 2 external interrupt lines and is connected to GIC as follows: pinX +------+ EXT_IRQ0 +------+ int 153 (for pinX) +------+ ------>| |--------->| |------------------->| | pinY | PIO | EXT_IRQ1 | EIC | int 154 (for pinY) | GIC | ------>| |--------->| |------------------->| | +------+ +------+ +------+ where PIO is the pin controller. Thank you, Claudiu Beznea Changes in v2: - fix compilation warning on bindings Changes in v2: - s/mchp/microchip in bindings - get rid of glitch filter settings - use s/eic@/interrupt-controller@ in bindings - removed '' around interrupts in bindings as proposed by Rob - removed glitch filter settings - switched to hierarchical irqchip driver - addressed review comments - use builtin_platform_driver instead of module_platform_driver Claudiu Beznea (2): dt-bindings: microchip,eic: add bindings irqchip/mchp-eic: add support .../interrupt-controller/microchip,eic.yaml | 73 ++++ MAINTAINERS | 6 + drivers/irqchip/Kconfig | 8 + drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-mchp-eic.c | 314 ++++++++++++++++++ 5 files changed, 402 insertions(+) create mode 100644 Documentation/devicetree/bindings/interrupt-controller/microchip,eic.yaml create mode 100644 drivers/irqchip/irq-mchp-eic.c
