Re: [PATCH net-next 0/5] net: mdio: add timestamped MDIO writes for PHY gettimex64

For example, using PTP_SYS_OFFSET_EXTENDED on the Raspberry Pi CM5 to
synchronize the system clock from the BCM54210PE PHY PHC leads to the
system clock being 32 µs ahead of the PHC. On the CM4, it is about 7 µs.
(The difference is because the MDIO clock frequency is higher on the
CM4: 10 MHz as opposed to 2.08 MHz on the CM5.)

IEEE 802.3 says the clock should be 2.5Mhz. Does the CM4 use a
clock-frequency DT property to enable this faster clock?
