Subject: [PATCH] dt-bindings: serial: 8250: Allow unconnected interrupts
Date: Tue, 3 Nov 2026 16:44:09 -0600 [thread overview]
Message-ID: <20261103224409.865130-1-robh@kernel.org> (raw)
8250-compatible UARTs can operate without a connected interrupt, using
polling. Requiring interrupts rejects valid descriptions such as the
HIP06 LPC UART.
