From 287bdea77529e6abac5fe15461d93c1acdcb07e9 Mon Sep 17 00:00:00 2001 From: Suraj Gupta Date: Thu, 25 Jun 2026 21:40:16 +0530 Subject: [PATCH] dt-bindings: dma: xlnx,axi-dma: Restore xlnx,flush-fsync as u32 The DT schema conversion incorrectly changed xlnx,flush-fsync from a u32 property to a boolean. The original binding documented values 1, 2, and 3 to select which VDMA channel(s) flush on frame sync. Restore the uint32 type with the documented enum values and fix the example accordingly.
