From af34a25336edf7f8978ee4066ac068d03dbe4e2f Mon Sep 17 00:00:00 2001 From: "Rob Herring (Arm)" Date: Mon, 13 Oct 2025 16:31:35 -0500 Subject: [PATCH] dt-bindings: watchdog: Convert TI OMAP to DT schema Convert the TI OMAP watchdog binding to DT schema format. The compatible string list was incomplete. The "reg" and "interrupts" properties were missing. "ti,hwmods" is also deprecated and not required.
