While at it, can we also add:
--- a/arch/arm64/boot/dts/marvell/armada-37xx.dtsi
+++ b/arch/arm64/boot/dts/marvell/armada-37xx.dtsi
@@ -71,6 +71,7 @@ soc {
compatible = "simple-bus";
#address-cells = <2>;
#size-cells = <2>;
+ dma-coherent;
ranges;
internal-regs@d000 {
so that to enable it for all bus-attached interfaces? This safe and
will boost IO performance.
Thanks,
Marcin
