From 6f997d4bb98becdc5d23affe207b3b0e854bcc3b Mon Sep 17 00:00:00 2001 From: Serge Semin Date: Fri, 9 Sep 2022 22:35:59 +0300 Subject: [PATCH] dt-bindings: ata: ahci-platform: Move dma-coherent to sata-common.yaml Seeing doubtfully any SATA device working without embedded DMA engine let's permit the device nodes being equipped with the dma-coherent property in case if the platform is capable of cache-coherent DMAs. As a side-effect we can drop the explicit dma-coherent property definition from the particular device schemas. Currently it concerns the Broadcom SATA AHCI controller only.
