Subject: [PATCH v7 01/23] dt-bindings: ata: ahci-platform: Move dma-coherent to sata-common.yaml
Date: Mon, 22 Aug 2022 21:37:06 +0300 [thread overview]
Message-ID: <20220822183728.24434-2-Sergey.Semin@baikalelectronics.ru> (raw)
In-Reply-To: <20220822183728.24434-1-Sergey.Semin@baikalelectronics.ru>
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.

Changelog v2:
- This is a new patch created after rebasing v1 onto the 5.18-rc3 kernel.
Changelog v4:
- Move the dma-coherent property to the sata-common.yaml schema instead
of removing it.
- Remove the Hannes' rb tag.
