[PATCH 06/11] arm64: dts: ls1043a: add missing dma ranges property

From: Li Yang <hidden>
Date: 2022-08-24 22:37:25
Also in: linux-devicetree, lkml
Subsystem: arm/freescale imx / mxc / layerscape arm architecture, the rest · Maintainers: Frank Li, Sascha Hauer, Linus Torvalds

From: Laurentiu Tudor <laurentiu.tudor@nxp.com>

ls1043a has a 48-bit address size so make sure that the dma-ranges
reflects this. Otherwise the linux kernel's dma sub-system will set the
default dma masks to full 64-bit, badly breaking dmas.
