[PATCH 19/21] arm64: dts: ls104x: add missing dma ranges property

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Laurentiu Tudor <laurentiu.tudor@xxxxxxx>

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.
