Axel Lin 1cb7b43f67 regulator: pbias: Fix is_enabled callback implementation
The is_enabled implementation is wrong in some cases:
e.g. for pbias_mmc_omap5: enable_mask is : BIT(27) | BIT(25) | BIT(26)
However, pbias_regulator_enable() only sets BIT(27) | BIT(26) bits.
So is_enabled callback will always return false in this case.
Fix the logic to compare the register value with info->enable rather than
info->enable_mask.

Krzysztof Kozlowski f4fbb3ce34 regulator: s5m8767: Fix carried over ena_gpio assignment
During registration of regulators if external control for regulator was
set in DTS the ena_gpio and ena_gpio_flags fields of regulator_config
were set to proper values.

However the same regulator_config was used in next iterations of loop so
the ena_gpio fields carried over to next regulators.

The issue was not observed as ena_gpio is supported only for Buck9
regulator which is often the last regulator parsed from DTS.
Be sure to clear ena_gpio config fields before registering the
regulator.

Remove checking control_reg in [set|get]_voltage_sel and then convert to use
regulator_[set|get]_voltage_sel_regmap for [set|get]_voltage_sel callbacks.

The anatop-reg-offset property is a required property rather than optional
property. So the question is what is the meaning of setting anatop-reg-offset
to 0? If 0 is a valid setting for anatop-reg-offset and it has special meaning,
we had better document it in the binding document. Otherwise, remove the testing
for control_reg in the driver.

No anatop voltage regulator node in the dts files set anatop-reg-offset to 0.
So I think it's safe to remove testing if control_reg is 0.

Axel Lin d6fe2c7251 regulator: tps6586x: Remove unnecessary rdev[] array
Now we are using devm_regulator_register(), so we don't need the rdev[] array
to store return value of devm_regulator_register. Use a *rdev variable is
enough for checking return status.

Colin Ian King f377ed107b regulator: da9063: fix assignment of da9063_reg_matches to NULL
cppcheck detected an incorrect assignment:

 drivers/regulator/da9063-regulator.c:711]: (warning) Assignment
 of function parameter has no effect outside the function

the original code didn't do anything, instead, *da9063_reg_matches
needs to be set to NULL.

Matt Porter 462c9fc5cb regulator: add bcm590xx regulator driver
Add a regulator driver for the BCM590xx PMU voltage regulators.
The driver supports LDOs and DCDCs in normal mode only. There is
no support for low-power mode or power sequencing.

Do not allocate memory for 'struct regulator_dev *' since it was removed
from state container (values returned by devm_regulator_register() are
not used outside of probe).

Use managed devm_regulator_register to simplify the driver probe and
driver remove functions. This allows removing from state container the
pointer to regulator_dev returned on registering the regulator.

Patch also removes from state container pointer to 'struct device' as it
is not used anywhere outside of max8952_pmic_probe() function.
