Hi Krzysztof,
Once again, thanks for the review and reply.
SO If we apply Chenyu's suggestion:
+ example:
+ -|
+ soc {
+
+ disp_ovl0_exdma2: dma-controller@32850000 {
+ compatible = "mediatek,mt8196-exdma";
+ reg = <0 0x32850000 0 0x1000>;
+ clocks = <13>;
+ power-domains = <12>;
+ mediatek,larb = <88>;
+ iommus = <&mm_smmu 144>;
+ #dma-cells = <1>;
+ };
+ };
Does this work for decoupling?
Best Regards,
Paul
