This is related to the regulators, specifically cold boot default values for ldo_ios causing the regulators to fail to register. You actually fixed this for the axp22x's before. There's also the addressing issue for the axp806. See the top of https://github.com/wens/linux/commits/sun9i-gmac-wifi for the bunch of fixes I need to send. > Anyways the u-boot side looks good. One issue I see is that your > optimus has an emmc, where as mine has a nand. We may want to > gave 2 optimus defconfigs for this once we've nand support. Hmm... This implies the need for 2 versions of dts files as well. Any ideas on probing for nand/emmc during boot?
