[PATCH v3 0/2] Add new ti,no-thermistor property

[PATCH v3 0/2] Add new ti,no-thermistor property

[Hermes Zhang]

The TS pin is used to detect the temperature and suspend the charging
when it's voltage out of range. If the NTC is not connect in HW, the
TS_IGNORE bit need to be set to 1 to make charge work. The new
"ti,no-thermistor" is used to set TS_IGNORE to 1 when HW doesn't work
with NTC.

Description from datasheet:
Battery temperature qualification voltage input. Connect a negative temperature
coefficient thermistor (NTC). Program temperature window with a resistor divider
from REGN to TS to GND. Charge and Boost mode suspend when TS pin voltage is
out of range. When TS pin is not used, connect a 10-kΩ resistor from REGN to TS
and a 10-kΩ resistor from TS to GND or set TS_IGNORE to HIGH to ignore TS pin.
It is recommended to use a 103AT-2 thermistor.

Notes:
    v2: change property name to ti,no-thermistor

    v3: drop "|" in property description
