Hi Dave, please do not apply this series until it got a Tested-by from Emiliano.
Hi Emiliano, you reported [0] that you couldn't get dwmac-meson8b to work on your Odroid-C1. With your findings (register dumps, clk_summary output, etc.) I think I was able to find a fix: it consists of two patches (which you find in this series) Unfortunately I don't have any Meson8b boards with RGMII PHY so I could only partially test this (I could only check if the clocks were calculated correctly when using a dummy 500002394Hz input clock instead of MPLL2). Could you please give this series a try and let me know about the results? You obviously still need your two "ARM: dts: meson8b" patches which - add the amlogic,meson8b-dwmac" compatible to meson8b.dtsi - enable Ethernet on the Odroid-C1 I have tested this myself on a Khadas VIM (GXL SoC, internal RMII PHY) and a Khadas VIM2 (GXM SoC, external RGMII PHY). Both are still working fine (so let's hope that this also fixes your Meson8b issue :)).
