Add nvmem cells for getting charge control thresholds if they have

Have you verified that e.g.
connecting the charger
setting the charge threshold
rebooting to windows
rebooting to windows once more for good measure
rebooting to linux
still has the settings persist?
Hmm I have tried several things but I can't seem to get the values to stick. I
the spmi-sdam driver is compiled in, I am not quite sure if I might be missing
something.
Hm, I wonder if Windows/UEFI overwrites these values or whether they're
used by something else..
Can you set a threshold in windows and see if Linux can read back that
data?
the values in /sys/class/power_supply/jada-jada/ are zero when rebooting from
Windows into Linux after enabling charge limitting in the Asus application.
I remember my old vivobook (x86) also forgot its settings each boot, but given
the nvmem cells that should not be happing here I guess. It is odd that there
seems to be no collision between Windows and Linux. Maybe the Windows mechanism
is doing the old trick of writing it in there every boot?
Odd indeed.. Does it work if you reboot from Linux to Linux?
It seems not, I seem to remember testing it quite some time ago, but I
cannot get it to remember any way, at least it is not popping up in
sysfs, always back to 0
Kind regards,
Maud
