Hi Krzysztof, Thanks very much for your quickly review. I think it is ok if it go through memory tree. In the original patch, we pm_runtime_get(smi-common-dev) in the smi-larb's pm resume callback. This patch only use device-link do this. thus, this patch have no function change. it only adjusts the SMI internal code flow. In addition, [14/16] expects your Acked-by. and that one should be merged with the others. About the others patches, I'm not sure which tree they should go through. they cross several trees, dt-binding/iommu/media/drm/dts. Not sure if Matthias could have time to review and give some suggestion. > > Best regards, > Krzysztof > > _______________________________________________ > Linux-mediatek mailing list > Linux-mediatek@xxxxxxxxxxxxxxxxxxx > http://lists.infradead.org/mailman/listinfo/linux-mediatek
