[PATCH 1/2] dt-bindings: serial: 8250: add Microchip Core16550
From: Kohei Otsuka via B4 Relay
Date: Mon Nov 02 2026 - 19:12:00 EST
From: Kohei Otsuka <kohei@xxxxxxxxxxxxxxxxx>
Core16550 is a 16550-compatible UART soft IP core for Microchip FPGAs,
including the fabric of PolarFire SoC. Its registers follow the 16550A,
so ns16550a stays the fallback, but it raises no interrupt on TEMT,
which the driver has to know about to support RS-485 on it.
Add microchip,core16550 with ns16550a as the fallback.
