Hi Robert,
Thanks for the patches.

IPQ4019 ESS EDMA support is not yet in upstream Linux, and even when
eventually it is merged the node will not be compatible with U-Boot driver
as the Linux driver properly models the internal switch.
Is this going to cause dtc compile errors when the node eventually does
land upstream and gets pulled into U-Boot?
How hard would it be to adjust the U-Boot driver to work with the
upstream bindings?
Kind regards,
So, lets add the U-Boot additions DTSI for ESS EDMA for now.
