Subject: [PATCH 1/6] powerpc: dts: mvme5100: Drop #interrupt-cells from ISA node
Date: Mon, 2 Nov 2026 16:29:59 +0100 [thread overview]
Message-ID: <20261102152957.300019-9-blum@kernel.org> (raw)
In-Reply-To: <20261102152957.300019-8-blum@kernel.org>
The ISA node does not provide interrupts. Its interrupt-parent property
points to the i8259 controller, which already defines #interrupt-cells.
Remove the #interrupt-cells property from the ISA node to fix the
following dtc warning:
Warning (interrupt_provider): /pci@feff0000/isa:
'#interrupt-cells' found, but node is not an interrupt provider
Fixes: be2019816e4d ("powerpc/embedded6xx: Add support for Motorola/Emerson MVME5100")
