    power: supply: bq24190_charger: Add support for bq24192i · 99c88eb2

    The bq24192 and bq24192i are mostly identical to the bq24190, TI even
    published a single datasheet for all 3 of them. The difference
    between the bq24190 and bq24192[i] is the way charger-type detection
    is done, the bq24190 is to be directly connected to the USB a/b lines,
    where as the the bq24192[i] has a gpio which should be driven high/low
    externally depending on the type of charger connected, from a register
    level access pov there is no difference.
    
    The differences between the bq24192 and bq24192i are:
    1) Lower default charge rate on the bq24192i
    2) Pre-charge-current can be max 640 mA on the bq24192i
    
    On x86/ACPI systems the code which instantiates the i2c client may not
    know the exact variant being used, so instead of coding the model-id
    in the i2c_id struct and bailing if it does not match, check the reported
    model-id matches one of the supported variants.
    
    This commit only adds support for the bq24192i as I don't
    have a bq24192 to test with, adding support for the bq24192 should
    be as simple as also accepting its model-id in the model-id test.
