Subject: [PATCH] dt-bindings: mmc: arasan,sdhci: Allow "dma-coherent" property
Date: Mon, 15 Dec 2025 15:27:50 -0600 [thread overview]
Message-ID: <20251215212751.3321878-1-robh@kernel.org> (raw)
The Arasan SDHCI controller is DMA coherent on the APM merlin SoC, so allow
the dma-coherent property. No reason implementations can't also be coherent
and there's not an SoC specific compatible, so allow it on any platform.
Signed-off-by: Rob Herring (Arm) <robh@kernel.org>
