Subject: [PATCH 4/4] dt-bindings: interrupt-controller: aspeed: Remove legacy AST2700 interrupt binding
Date: Thu, 5 Feb 2026 14:07:22 +0800 [thread overview]
Message-ID: <20260205-irqchip-v1-4-b0310e06c087@aspeedtech.com> (raw)
In-Reply-To: <20260205-irqchip-v1-0-b0310e06c087@aspeedtech.com>
Remove the legacy AST2700 interrupt controller Devicetree binding.
The legacy binding was limited to a PSP-centric view of the interrupt
architecture and cannot describe interrupt routing and protection for
the full AST2700 system.
It is superseded by the new ASPEED AST2700 INTC0/INTC1 binding, which
describes the interrupt controllers at the block-function level.
There are no known upstream users of the removed binding.

-title: Aspeed AST2700 Interrupt Controller
-
-description:
- This interrupt controller hardware is second level interrupt controller that
- is hooked to a parent interrupt controller. It's useful to combine multiple
- interrupt sources into 1 interrupt to parent interrupt controller.

- Depend to which INTC0 or INTC1 used.
- INTC0 and INTC1 are two kinds of interrupt controller with enable and raw
- status registers for use.
- INTC0 is used to assert GIC if interrupt in INTC1 asserted.
- INTC1 is used to assert INTC0 if interrupt of modules asserted.
