MDC clock period between ethernet MAC and PHY

Hello, I'm using peta-linux 2017.4 with an zynq ultrascale+ chip. I want to change the clock frequency of MDIO interface between ethernet MAC and PHY.  Currently, it's about 3.125MHZ and I want to change it to 2MHZ. 

How should I do? Modify device tree file?
