arm64: dts: meson: add ethernet fifo sizes (ef68984e) · Commits · 戴 / test

If unspecified in DT, the fifo sizes are not automatically detected by the dwmac1000 dma driver and the reported fifo sizes default to 0. Because of this, flow control will be turned off on the device. Add the fifo sizes provided by the datasheets in the SoC in DT so flow control may be enabled if necessary. Signed-off-by:
