[PATCH 09/12] riscv: dts: starfive: Add dma-noncoherent for JH7100 SoC

From: Cristian Ciocaltea <hidden>
Date: 2023-02-11 03:19:56
Also in: linux-devicetree, linux-riscv, lkml, netdev
Subsystem: risc-v architecture, starfive devicetrees, the rest · Maintainers: Paul Walmsley, Palmer Dabbelt, Albert Ou, Emil Renner Berthing, Conor Dooley, Linus Torvalds

The RISC-V architecture is by default coherent, as indicated by
CONFIG_OF_DMA_DEFAULT_COHERENT, but the StarFive JH7100 is not, hence
provide the dma-noncoherent property to the soc DT node.
