[PATCH] sunxi: H6: Enable Ethernet on Orange Pi One Plus
Enable Ethernet on Orange Pi One Plus by using the correct phy for Realtek RTL8211E instead of the Generic One. Also use CONFIG_MACPWR to turn on ethernet on startup.
After this patch is applied, a few issues can be seen:
- there's still a PHY reset timed out error that doesn't seem to cause any impacts to the overall connection
- sometimes the emac driver times out after reset (yellow LED turns on and never blinks)
For future patches: for now, CONFIG_MACPWR is the only way to enable Ethernet on boot. There's already code on the dts for using the 3v3-gmac regulator. However, it is not probed on boot, so it only starts after a "regulator status" command is issued.
More details about the troubleshooting on [1].

So this is really odd, why would you need that? 001c.c915 is the ID for the normal standard Realtek 8211E PHY, which would be auto-detected via MDIO. You just need to define CONFIG_PHY_REALTEK to include support. Forcing this in the DT is not necessary and smells wrong.
But I suppose you needed that to get it to work, so could this be a timing issue? Maybe the PHY doesn't come up quick enough after just pulling PD6 high, so the auto-detection wouldn't work? The DT has a "startup-delay-us = <100000>;" property, which MACPWR doesn't know about and wouldn't observe. So could you check whether just applying the "Remove MACPWR" patch, plus adding "CONFIG_SUN8I_EMAC=y" and "CONFIG_PHY_REALTEK=y" to defconfig fixes the issue? You may need to enable CONFIG_DM_REGULATOR_FIXED=y as well, although this would become standard for all sunxi boards soon.
And you must NOT use SUNXI_SETUP_REGULATORS=0 in TF-A, as you need ALDO2 to be set up by TF-A. We introduced this build option to accommodate the OrangePi 3 board, which requires a specifically timed regulator setup, which both TF-A and U-Boot would not observe. To not crash the PHY with any incorrect regulator setup, we use this option to make at least Linux work. The side effect is that some peripherals (HDMI, Ethernet) will not work in U-Boot. Also please note that a reset from Linux might not affect the PMIC, so there might be different behaviour between and cold and warm boot.

Hello
Note that there is already a try to fix this in upstream linux: The v4 can be found at https://lore.kernel.org/linux-arm-kernel/Y3RDumClNkEW6L4F@lunn.ch/T/
And that I will send soon my last version https://github.com/montjoie/linux/tree/opi3-v5

Awesome! Once this gets merged, I can try to implement this on the orange pi one plus (I believe your patch, although generic and supported by a few boards, doesn't support the Orange Pi One Plus, right?).
Thanks for letting me know!

Hey Andre! Apologies for the mess! I'll let folks from meta-sunxi know and remove the patch for now from their layer.

Interesting, I really tried using CONFIG_PHY_REALTEK but it never reached the code that detected the PHY, making it only detect the Generic PHY.
But I suppose you needed that to get it to work, so could this be a timing issue? Maybe the PHY doesn't come up quick enough after just pulling PD6 high, so the auto-detection wouldn't work? The DT has a "startup-delay-us = <100000>;" property, which MACPWR doesn't know about and wouldn't observe.
That sounds like it! When I was troubleshooting, I noticed that PHY detection (for the Generic PHY) was really intermittent.
So could you check whether just applying the "Remove MACPWR" patch, plus adding "CONFIG_SUN8I_EMAC=y" and "CONFIG_PHY_REALTEK=y" to defconfig fixes the issue? You may need to enable CONFIG_DM_REGULATOR_FIXED=y as well, although this would become standard for all sunxi boards soon.
Will take a look! Unfortunately I lost my PC :( so I will probably take a little why to resume my troubleshooting.
And you must NOT use SUNXI_SETUP_REGULATORS=0 in TF-A, as you need ALDO2 to be set up by TF-A. We introduced this build option to accommodate the OrangePi 3 board, which requires a specifically timed regulator setup, which both TF-A and U-Boot would not observe.

DT change has to be merged by the Linux tree first. Try to work on that gets approved.
