power: supply: bq25890: Support higher charging voltages through Pump Express+ protocol
Add a "linux,pump-express-vbus-max" property which indicates if the Pump
Express+ protocol should be used to increase the charging protocol.
If this new property is set and a DCP charger is detected then request
a higher charging voltage through the Pump Express+ protocol.
So far this new property is only used on x86/ACPI (non devicetree) devs,
IOW it is not used in actual devicetree files. The devicetree-bindings
maintainers have requested properties like these to not be added to the
devicetree-bindings, so the new property is deliberately not added
to the existing devicetree-bindings.
Changes by Hans de Goede:
- Port to my bq25890 patch-series + various cleanups
- Make behavior configurable through a new "linux,pump-express-vbus-max"
device-property
- Sleep 1 second before re-checking the Vbus voltage after requesting
it to be raised, to ensure that the ADC has time to sampled the new Vbus
- Add VBUSV bq25890_tables[] entry and use it in bq25890_get_vbus_voltage()
- Tweak commit message
