arm64: dts: k3-am625-verdin-r5: ethernet clocking workaround
Currently only the SPL running on the R5 has a clock driver. As a
workaround therefore move the assigned-clock stuff required for our
ETH_25MHz_CLK from the cpsw3g_mdio node of the regular device tree to
the a53@0 node of the R5 device tree.
Upstream-Status: Pending
Initial U-Boot to be used for bring-up and validation of the V1.0
design, we'll decide on the step forward to mainline this once the
bring-up and validation will be done.
