Subject: [PATCH] dt-bindings: serial: Allow fsl,ns16550 with broken FIFOs
Date: Sun, 09 Feb 2025 23:13:40 +0100 [thread overview]
Message-ID: <20250209-uartfifo-v1-1-501a510a5f07@posteo.net> (raw)
From: "J. Neuschäfer" <j.ne@posteo.net>
While testing on a Freescale MPC8314E board, I noticed that changing
the UART compatible string from ns16550 to ns16550a breaks the output,
suggesting that the FIFOs don't work correctly. To accommodate this
fact, move the definition of fsl,ns16550 to the section of 8250.yaml
that allows broken FIFOs.
