The Amazon's Annapurna Labs FIC (Fabric Interrupt Controller) has 32 inputs/sources. This FIC may be cascaded into another FIC or connected directly to the main CPU Interrupt Controller (e.g. GIC). Changes since v3: ================= - tightened the verification for supported trigger types - updated dt-binding's example to meet the binding description (interrupt-cells to 2) - added description to interrupt-cells to explain each field - changed pr_err to pr_debug inside al_fic_irq_set_type in order to allow the user to enable printouts for verbose information in case of errors Changes since v2: ================= - updated dt-bindings to use proper format for entry name - removed kernel-doc format style from Copyright - removed unneeded/misplaced selects from Kconfig - changed used mmio operation to relaxed flavor - changed error return value from EPERM to EINVAL int case of attempting to reconfigure the FIC after it has been configured - fixed commenting format - used drivers define instead of subsystem internals - moved al_fic_hw_init function to caller - removed al_fic_wire_get_domain from documentation - removed argument validation from al_fic_wire_init Changes since v1: ================= - removing unused exported APIs - updating cover letter and commit message accordingly Talel Shenhar (2): dt-bindings: interrupt-controller: Amazon's Annapurna Labs FIC irqchip: al-fic: Introduce Amazon's Annapurna Labs Fabric Interrupt Controller Driver .../interrupt-controller/amazon,al-fic.txt | 29 +++ MAINTAINERS | 6 + drivers/irqchip/Kconfig | 8 + drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-al-fic.c | 278 +++++++++++++++++++++ 5 files changed, 322 insertions(+) create mode 100644 Documentation/devicetree/bindings/interrupt-controller/amazon,al-fic.txt create mode 100644 drivers/irqchip/irq-al-fic.c -- 2.7.4
