- Enable end of charge monitoring once, it doesn't need to be disabled
- Acknowledge the first (wrong) end of charge interrupt on charger enable
(this had been broken in r25299)
- Centralize reads to ENRD* registers and cache the results when needed
- on PP it is not needed because reads are atomic, we only check for
end of charge when the charging, and for charger presence when
discharging
as3525v2 (using as3543) specifics
- I got the datasheet today from AMS, thanks to them for being so fast
and not require me to sign tons of papers!
- USB detection now works on as3525v2 using the as3543. Clip+ won't
reboot to OF yet, it needs mkamsboot support first (usbstack disabled)
- Charging should work, the CHARGER register is at a different place, it
is an extended PMU register -> use ascodec_read/write_charger() to
access it
- real interrupts are not used yet for ENRD, we get thousands of
interrupts per second, apparently only limited by the i2c clock.
