So while the "ethernet-phy-ieee802.3-c22" compatible would work for both, the "ethernet-phy-id001c.c916" compat effectively disables phy- probing. So applying this patch would effectively disable ethernet support on those older rock-pi-e boards? In a similar context concerning boards using different phys, it was suggested [0] that the bootloader should modify the dt it passes to the kernel to provide the correct phy id. > reg = <1>; > pinctrl-0 = <ð_phy_int_pin>, <ð_phy_reset_pin>; > pinctrl-names = "default"; > interrupt-parent = <&gpio1>; > interrupts = <24 IRQ_TYPE_LEVEL_LOW>; > - reset-assert-us = <10000>; > - reset-deassert-us = <50000>; > + reset-assert-us = <20000>; > + reset-deassert-us = <100000>; I guess for those we can consolidate onto the "slower" ones in the kernel though. > reset-gpios = <&gpio1 RK_PC2 GPIO_ACTIVE_LOW>; > + max-speed = <1000>; > }; > }; > }; > Heiko [0] https://lore.kernel.org/all/ecbdcfb7-32ab-45cc-991a-982c52bf4b14@xxxxxxxxx/
