No dsme checking battery temperature and does not handle bq24510
timer (previously this was in closed bme daemon which
functionality is now in kernel drivers). But dsme daemon also
kicking tlw4030 watchdog, so when daemon dies after 30s tlw4030
reboot device.
But right you can implement correctly this in userspace (e.g.
when daemon not running/crashed, you can restart daemon or reboot
system or disable charing, whatever...) and you do not need to
have it in kernel...
