Date: Wed, 24 Aug 2022 18:11:55 -0500 From: Li Yang <leoyang.li@....com> To: shawnguo@...nel.org, devicetree@...r.kernel.org Cc: robh+dt@...nel.org, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, Laurentiu Tudor <laurentiu.tudor@....com>, Li Yang <leoyang.li@....com> Subject: [PATCH 4/9] arm64: dts: ls1046a: add missing dma ranges property From: Laurentiu Tudor <laurentiu.tudor@....com> ls1046a 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.
