| 4 | Subject: [PATCH] arm64: dts: ls104x: add missing dma ranges property |
| 5 | |
| 6 | These chips have a 48-bit address size so make sure that the dma-ranges |
| 7 | reflects this. Otherwise the linux kernel's dma sub-system will set |
| 8 | the default dma masks to full 64-bit, badly breaking dmas. |
