8a23b4e03d regulator: core: Fix logic to determinate if regulator can change voltage
Having a linear_min_sel setting means the first linear_min_sel selectors are
invalid. We need to subtract linear_min_sel when use n_voltages to determinate
if regulator can change voltage.

da130ab2df regulator: s5m8767: Fix to read the first DVS register.
This patch modifies the DVS register read function to select correct DVS1
register. This change is required because the GPIO select pin is 000 in
unintialized state and hence selects the DVS1 register.

3708903ee6 regulator: gpio-regulator: gpio_set_value should use cansleep
If it's possible for gpio_set_value to sleep, we should be using
the *_cansleep call instead. This patch fixes multiple warnings

ad0b8b9e82 regulator: gpio-regulator: Fix logical error in for() loop
The cond-statement of this particular for() loop will always be
true as long as at least one voltage-shifting GPIO is present.
If it wasn't for the break below, we'd be stuck in a forever loop.
This patch inserts the correct cond-statement into the statement.

985884db50 regulator: anatop: Use linear_min_sel with linear mapping
By setting linear_min_sel to anatop_reg->min_bit_val, we can avoid
adjust the anatop_reg->min_bit_val offset in [set|get]_voltage_sel.

With this chance we can refactor this driver to use
regulator_[get|set]_voltage_sel_regmap.

4efd9dfecb regulator: max1586: Implement get_voltage_sel callback
This is required since commit f7df20ec32
"regulator: core: Use list_voltage() to read single voltage regulators",
otherwise _regulator_get_voltage returns rdev->desc->ops->list_voltage(rdev, 0).

The Maxim 1586 controls V3 and V6 voltages, but offers no way of reading back
the set up value. Thus this patch caches the setting when setting new voltage.

05cf34c1af regulator: pcf50633: Use linear_min_sel and regulator_[map|list]_voltage_linear
This driver can be converted to use linear_min_sel and
regulator_[map|list]_voltage_linear.

Below shows the equation (from Datasheet) for each LDOs.

For AUTOOUT:
        VO(prog) = 0.625 + auto_out x 0.025 V; e.g.
        (00000000 to 00101110: reserved)
        00101111: 1.8 V (min)
        01010011: 2.7 V
        01101010: 3.275 V
        01101011: 3.300 V
        01101100: 3.325 V
        01111111 : 3.800 V (max)

        The linear mapping start from 0x2f selector.

        Thus we convert this equation to:
        VO(prog) = 1.8 + (selector - linear_min_sel) x 0.025 V
        (min_uV = 1800000, uV_step = 25000, linear_min_sel = 0x2f)

For DOWNxOUT:
        VO(prog) = 0.625 + downx_out x 0.025 V; e.g.
        00000000 : 0.625 V (min)
        00010111 : 1.200 V
        00101111 : 1.800 V
        01011111 : 3.000 V (max)

For xLDOOUT:
        VO(prog) = 0.9 + xldo_out x 0.1 V; e.g.
        00000: 0.9 V
        00001: 1.0 V
        11000 : 3.3 V
        11011 : 3.6 V
