MLK-11460 ARM: dts: imx6sx: enet RGMII TXCLK output drive strength is weak
The current enet RGMII TXCLK rise/fall time which could be observed(~0.85ns)
is longer than requirement (<=0.75ns).
The current setting, SPEED/DSE/SRE=10/110/1 is used, and then it needs to
increase DSE to 111 "37 Ohm @ 3.3V, 21 Ohm@1.8V, 34 Ohm for DDR". After the
change RGMII TXCLK match the spec requirement.
