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
