Subject: [PATCH 1/2] dt-bindings: serial: 8250: Explicitly make LPC32xx UARTs compatible with 16550A
Date: Sat, 10 Jan 2026 04:46:46 +0200 [thread overview]
Message-ID: <20260110024647.3389345-2-vz@mleia.com> (raw)
In-Reply-To: <20260110024647.3389345-1-vz@mleia.com>
NXP LPC32xx SoC has 4 16550A compatible UARTs with 64 byte TX and RX FIFO
sizes, and the platform UART hardware is well supported as a standard
16550A UART.
