I don't consider it a "release blocker". The defconfig is just what it says: a default configuration.

Feel free to send a patch for it to a...@kernel.org in addition to the usual recipients (Chen-Yu, LAKML and myself), and make it clear that you want them to apply it. Thanks!

Is this considered an issue worthwhile to be addressed before the release of 4.4? The way I see it is that USB support is broken on A10/20 in mainline for anybody who builds on sunxi_defconfig or multi_v7_defconfig at the moment. I think we should either have CONFIG_PHY_SUN4I_USB select CONFIG_AXP20X_POWER automatically (my preferred solution) or at least add it to sunxi_defconfig and multi_v7_defconfig. I'd be glad to submit a short patch for it depending on your viewpoint.

I need to check my emails more often, I just spent several hours narrowing this down but not quite reaching the solution. Karsten's working config posted earlier defines CONFIG_AXP20X_POWER=m.
