[PATCH v4] imx: add i.MX8MN DDR3L evk board support
Add the support for the 8MNANOD3L-EVK board. The board has an i.MX8MNano UltraLite Quad SoC and uses 1GB DDR3L memory.

I saw that you added the PCA9450 driver. Do you know if this initialization can be done by the driver when CONFIG_SPL_DM_REGULATOR is enabled? If I see this correctly, it can't be done. Is that correct?

It took me a little while to understand what was meant by this. In the meantime I could change the PMIC/Regulator initialization to DT/DM and can make the setting so. What is not clear to me yet is at which point this should be done (regulators_enable_boot_on()). Currently I do it in the board/spl specific board_init_f().
Do any of you have any advice here?
Thanks

I saw that you added the PCA9450 driver. Do you know if this initialization can be done by the driver when CONFIG_SPL_DM_REGULATOR is enabled? If I see this correctly, it can't be done. Is that correct?

Maybe something like this should work. Now question is about
should be
done in pre-reloc or not
It took me a little while to understand what was meant by this. In
the
meantime I could change the PMIC/Regulator initialization to DT/DM and can make the
setting so.
What is not clear to me yet is at which point this should be done (regulators_enable_boot_on()). Currently I do it in the board/spl specific board_init_f().
Do any of you have any advice here?

From code I navigate spl_early_init should bind the driver in pre-reloc

It took me a little while to understand what was meant by this. In the meantime I could change the PMIC/Regulator initialization to DT/DM and can make the setting so. What is not clear to me yet is at which point this should be done (regulators_enable_boot_on()). Currently I do it in the board/spl specific board_init_f().
Do any of you have any advice here?
After having a discussion with you, i found that maybe i have some problem and some of the setting should be done before ddr inizialization. I will take a look on it on afternoon. I know marek was working on some way to probe driver during binding and we need even to be sure that this can happen before memory training.
Currently I added it in board_init_f() right before spl_dram_init() [1] and it works. I also tried to put it in power_init_board() [2] but this does not work.

Does it work if you mark pre-reoloc, pmic, i2c, and pinctrl?
I added on all nodes the u-boot,dm-pre-reloc but this does not help when trying to do the init in power_init_board().
From code I navigate spl_early_init should bind the driver in pre-reloc
What function should be called to probe the driver? Currently I use regulators_enable_boot_on().

Hi Heiko
Did you solve it after your patch on regulator?
