I have networking enabled on top of this series here.

ssh://git@...bucket.itg.ti.com/~x1045550/ti-priv-linux-kernel.git ti-linux-5.4.y-for-next-pull

But DMA failed for Main domain.
     0.781005] ti-udma 31150000.dma-controller: NAVSS ti,sci-dev-id read failure -22
[    0.788684] ti-udma: probe of 31150000.dma-controller failed with error -22
