From 55620b11186c81757b05fb8e2df9ddc7127d6fd2 Mon Sep 17 00:00:00 2001 From: Guodong Xu Date: Mon, 18 May 2026 11:32:41 +0800 Subject: [PATCH] dt-bindings: dmaengine: Add SpacemiT K3 DMA compatible string Add the "spacemit,k3-pdma" compatible string for the SpacemiT K3 SoC. While the K3 PDMA IP reuses most of the design found on the earlier K1 SoC, a new compatible string is required because the DRCMR (DMA Request/Command Register) base address for extended DMA request numbers (>= 64) differs from the K1 implementation.
