Subject: [PATCH v2 3/3] arm64: dts: allwinner: a523: Add missing GPIO interrupt
Date: Fri, 27 Mar 2026 11:30:06 +0000	[thread overview]
Message-ID: <20260327113006.3135663-4-andre.przywara@arm.com> (raw)
In-Reply-To: <20260327113006.3135663-1-andre.przywara@arm.com>

Even though the Allwinner A523 SoC implements 10 GPIO banks, it has
actually registers for 11 IRQ banks, and even an interrupt assigned to
the first, non-implemented IRQ bank.
Add that first interrupt to the list of GPIO interrupts, to correct the
association between IRQs and GPIO banks.

This fixes GPIO IRQ operation on boards with A523 SoCs, as seen by
broken SD card detect functionality, for instance.

Signed-off-by: Andre Przywara <andre.przywara@arm.com>
