R40 (aka V40, A40i, T3) has two different Ethernet IP
called EMAC and GMAC.
EMAC only support 10/100 Mbit in MII mode,
while GMAC support both 10/100 (MII) and 10/100/1000 (RGMII).
In contrast to A10/A20 where GMAC and EMAC share the same pins
making EMAC
routed to port H.
Both EMAC (on port H) and GMAC (on port A)
can be then enabled at the same time, allowing for two ethernet ports.

no longer optional on R40
- Add a new DT compatible string for R40 EMAC
- Deassert reset line before enabling the clock
- minor fixes: formatting, DT node order, leftover pinctrl props

R40 (aka V40/A40i/T3) and A10/A20 share the same EMAC IP.
However, on R40 the EMAC is gated by default.

Add option to use with watchdog timers which are always enabled
in hardware, i.e. there is no way to enable/disable it via GPIO pin.
The driver will start pinging WDT immediately upon loading
and will continue to do so even after stopping the watchdog.

Why did you drop this check? It has nothing with w1-gpio driver
This check prevents master from implementing "set_pullup" provided
