Is your driver auto-loaded properly when built as a module? By auto-loading I
mean auto-loaded by udev, not by putting to some rc-script or other modprobe-
load scripts.

I failed to configure auto-loaded in rootfs generated by buildroot. I need time to dig it.

Anyway I add OF match table.

If you don't have udev/kmod working on your system, you can check if
the modalias reported in the driver's uevent sysfs entry is a valid
alias in the kernel module, i.e:

$ grep MODALIAS $(find -name uevent | grep act8945a-charger)
$ modinfo act8945a_charger | grep alias
