Full dmesg (with readreg/writereg debug printf output), well, up to the point of mounting root is attached. In OpenWrt sources, I found something interesting in the file at https://dev.openwrt.org/browser/trunk/target/linux/ar71xx/files/arch/mips/ath79/dev-eth.c - it looks like the function ath79_register_mdio (lines 176 - 267) should set mdio clock rate, and for 934x SoC it calls helper function ar934x_get_mdio_ref_clock (lines 151 - 174). Maybe some hint could be here, I don't know, I am not that familiar with OpenWrt sources, I just tested here both switches are working.
