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:
- 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.
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.
