b1a397dc1a regulator: max8952: Remove wrong set_suspend_disable callback setting
Using the same ops for both .disable and .set_suspend_disable callbacks is
actively broken. This patch removes .set_suspend_disable callback setting.

9c6a74c5e0 regulator: ad5398: Fix min/max current limit boundary checking
It is ok to request current limit with min_uA < chip->min_uA and
max_uA > chip->max_uA.

We need to set min_uA = chip->min_uA if (min_uA < chip->min_uA),
this ensures the equation to calcuate selator does not return negative number.

Also set max_uA = chip->max_uA if (max_uA > chip->max_uA), as suggested by

65f735082d regulator: core: Add core support for GPIO controlled enable lines
It is very common for regulators to support having their enable signal
controlled by a GPIO. Since there are a bunch of fiddly things to get
right like handling the operations when the enable signal is tied to
a rail and it's just replicated code add support for this to the core.

Drivers should set ena_gpio in their config if they have a GPIO control,
using ena_gpio_flags to specify any flags (including GPIOF_OUT_INIT_ for
the initial state) and ena_gpio_invert if the GPIO is active low. The
core will then override any enable and disable operations the driver has
and instead control the specified GPIO.

This will in the future also allow us to further extend the core by
identifying when several enable signals have been tied together and
handling this properly.

1e12dfc968 regulator: tps6524x: Convert fixed ilimsel to table based
This patch refactors the code to get rid of the fixed_ilimsel and FIXED_ILIMSEL
flag usage, and convert all the fixed ilimsel to table based (with one entry in
the table).

We can differentiate fixed ilimsel by checking info->n_ilimsels == 1,
thus FIXED_ILIMSEL flag can be removed.

This change makes the logic of the code simpler as all the ilimsels are table
based now.

e2eb169b1b regulator: s5m8767: Convert to regulator_list_voltage_linear
In current code, .list_voltage and .set_voltage_sel callbacks for BUCK7 and

This patch adds s5m8767_buck78_ops for BUCK7 and BUCK8 which does not set

effect of returning -EINVAL in the callbacks)

Then for all the users of s5m8767_list_voltage, we don't need to worry about
the case reg_voltage_map[reg_id] is NULL.
So we can convert s5m8767_list_voltage to regulator_list_voltage_linear.

f6442aa0b5 regulator: tps65910: Remove unused min_uV and max_uV from struct tps_info
The min_uV and max_uV fields of struct tps_info are not used in the code.
For the case voltage_table is provided, the min_uV and max_uV are the same
values as volt_table[0] and volt_table[n_voltages -1].
For the case voltage_table is not available, having the min_uV and max_uV seems
misleading. Current code uses equations to get the voltage value in this case,
but these equations do not use the min_uV and max_uV fields of struct tps_info.

Thus this patch removes the min_uV and max_uV fields from struct tps_info.
