    SubjectRE: [PATCH] regulator: Rename s5m8767_convert_voltage to s5m8767_get_proper_voltage_sel

    Convert means that Normal Voltage unit to 8767 internal voltage register
    > BTW, I'm also confused by s5m8767_set_high and s5m8767_set_low functions.

    S5M8767A can be controlled with 3 GPIO.
    To control voltage with GPIO, Order is very important.
    Because Voltage inversion should not be happened.
    If DVFS table is like a below,
    1.5Ghz 1.5V
    1.0Ghz 1.0V
    0.5Ghz 0.5V

    If System try to change 1.0Ghz(1.0V) -> 1.5Ghz(1.5V)
    Absolutely 0.5V should not be set.
