From: Guodong Xu Date: Mon, 18 May 2026 03:32:41 +0000 (+0800) Subject: dt-bindings: dmaengine: Add SpacemiT K3 DMA compatible string X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=55620b11186c81757b05fb8e2df9ddc7127d6fd2;p=thirdparty%2Fkernel%2Flinux.git 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.
