From 76619c4fce711acbfd732909644d40c1caf27041 Mon Sep 17 00:00:00 2001 From: "Rob Herring (Arm)" Date: Wed, 7 May 2025 10:49:36 -0500 Subject: [PATCH] dt-bindings: serial: Convert microchip,pic32mzda-uart to DT schema Convert the Microchip PIC32 UART binding to DT schema. The binding was unclear there are 3 interrupts. The functions were determined from the driver. The 'cts-gpios' property is covered by serial.yaml schema.
