Subject: [PATCH] arm64: dts: ls104x: add missing dma ranges property
|
||
|
|
|
||
|
|
These chips have 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.
|
||
