Good point. You should pass the following options:
CONFIG_DM_REGULATOR=y CONFIG_DM_REGULATOR_FIXED=y
One thing I realized is that on the defconfig and on Yocto, SPL is expected, so if I disable CONFIG_SPL, things break. I'm thinking about using it because CONFIG_DM_REGULATOR didn't seem to work?
I also decided to use CONFIG_SPL_DM_REGULATOR, but it doesn't compile :(
These are the configs I added
# This one I believe is needed for EMAC CONFIG_SPL_SPI_SUNXI=y # This one is needed by the DM and SPL_DM configs CONFIG_DM=y # These two seem to allow me to build with SPL CONFIG_SPL_BUILD=y CONFIG_SPL_POWER=y # This one breaks the build CONFIG_SPL_DM=y # Keeping these two commented until I fix SPL_DM #CONFIG_SPL_DM_REGULATOR=y #CONFIG_SPL_DM_REGULATOR_FIXED=y
I also had to patch drivers/mmc/sunxi_mmc.c to add an if macro on the only gpio_request_by_name it has, inspired by [1]. Will send a patch once I figure out why SPL is breaking.
Maybe it has to do with SPL memory? These are the errors I see when I enable CONFIG_SPL_DM:

I don't see them without CONFIG_SPL_DM.
This person [2] mentions in another similar issue that SPL is very tight in memory btw.

so that the GPIO3_6 turns on by default and then you would not need to run the "gpio set pd6" command.
That didn't work. I still had to enable with "gpio set pd6". Also, when it gets to the kernel, ethernet shuts down. I also don't see the device in my router, so I believe even though eth0 is up, something may not be working yet.
then dhcp command works :). However, it doesn't get an IP and with static IP pinging doesn't work.
