Name: AST2700-A2 interrupt controller hierarchy and route support
URL: https://patchwork.kernel.org/project/linux-riscv/list/?series=1062412
Version: 2

Introduce a new binding describing the AST2700 interrupt controller architecture implemented in the A2 production silicon. The AST2700 SoC has undergone multiple silicon revisions (A0, A1, A2) prior to mass production. The interrupt architecture was substantially reworked after the A0 revision for A1, and the A1 design is retained unchanged in the A2 production silicon. The existing AST2700 interrupt controller binding was written against the pre-production A0 design. That binding does not accurately describe the interrupt hierarchy and routing model present in A1/A2, where interrupts can be routed to multiple processor-local interrupt controllers (Primary Service Processor (PSP) GIC, Secondary Service Processor (SSP)/Tertiary Service Processor (TSP) NVICs, and BootMCU APLIC) depending on the execution context. Hardware connectivity between interrupt controllers is expressed using the aspeed,interrupt-ranges property.

The AST2700 interrupt fabric is shared by multiple integrated processors (PSP/SSP/TSP/BootMCU), each with its own interrupt controller and its own devicetree view of the system. As a result, interrupt routing cannot be treated as fixed: the valid route for a peripheral interrupt depends on which processor is consuming it. The INTC0 driver models this by creating a hierarchical irqdomain under the upstream interrupt controller selected by the interrupt-parent property in the devicetree. Information derived from this relationship is incorporated into the route resolution logic for the controller. The INTC1 driver implements the banked INTM-fed controller and forwards interrupts toward INTC0, without embedding assumptions about the final destination processor.

Add a KUnit suite for aspeed_intc0_resolve_route(). Cover invalid arguments, invalid domain/range data, connected and disconnected mappings, and malformed upstream range cases. Signed-off-by: Ryan Chen <ryan_chen@aspeedtech.com> Signed-off-by: Linux RISC-V bot <linux.riscv.bot@gmail.com>

The existing AST2700 interrupt controller driver ("aspeed,ast2700-intc-ic") was written against the A0 pre-production design. From A1 onwards (retained in the A2 production silicon), the interrupt fabric was re-architected: interrupt routing is programmable and interrupt outputs can be directed to multiple upstream controllers (PSP GIC, Secondary Service Processor (SSP) NVIC, Tertiary Service Processor (TSP) NVIC, and Boot MCU interrupt controller). This design requires route resolution and a controller hierarchy model which the A0 driver cannot represent. Remove driver support for A0 in favour of the driver for the A2 production design.

The existing AST2700 interrupt controller binding ("aspeed,ast2700-intc-ic") was written against the A0 pre-production design. In A0, the interrupt hierarchy effectively converged at the Primary Service Processor (PSP): INTC1 instances fed into INTC0, and INTC0 was wired to the PSP GIC. The binding therefore described a fixed, PSP aggregation model. From A1 onwards (retained in the A2 production silicon), the interrupt fabric was re-architected: interrupt routing is programmable and interrupt outputs can be directed to multiple upstream controllers (PSP GIC, Secondary Service Processor (SSP) NVIC, Tertiary Service Processor (TSP) NVIC, and Boot MCU interrupt controller). This design requires route resolution and a controller hierarchy model which the A0 binding cannot represent. Remove the binding for the pre-production A0 design in favour of the binding for the A2 production design. There is no significant user impact from the removal as there are no existing devicetrees in any of Linux, u-boot or Zephyr that make use of the A0 binding.
