From 4f0303d43973a4086d6355db0c653a5a369b5dbe Mon Sep 17 00:00:00 2001 From: Jerome Brunet Date: Thu, 18 Jul 2019 11:36:23 +0200 Subject: ARM: dts: meson8b: add ethernet fifo sizes 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 datasheet in the SoC in DT so flow control may be enabled if necessary.
