- Update to 4.14-final.

On the aarch64 based Pine64 board it has been observed that the updated
dtb-allwinner package now requires the axp20x-regulator module in the
initrd for using the MMC driver, and its parent module axp20x-rsb does
not get loaded automatically even if added to the initrd.

I would prefer if that would be fixed in the kernel by adding the proper
dependencies.
Is there any chance for that?

There's multiple issues at play here:

1)
[...]

2) axp20x-rsb driver does have MODULE_DEVICE_TABLE(of, ...), so it is
unclear to me why the DT -> module resolution for auto-loading is not
working here.

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/driv
ers/mfd/axp20x-rsb.c?h=v4.14

It is almost certainly an upstream kernel issue, possibly in sunxi-rsb
bus driver. Stefan has already reported this on #linux-sunxi.

The driver is missing a uevent trigger, without udev does not load any
dependent drivers.

Just sent a patch upstream, you can try this package:
https://build.opensuse.org/package/binaries/
home:StefanBruens:branches:devel:ARM:Factory:Contrib:Pine64/kernel-sunxi64?
repository=standard

You still need to add "sunxi-rsb axp20x-regulator axp20x-rsb" to add_drivers.

Kind regards,

Stefan
