We should always be able to probe a regulator with no platform data. This
will enable readback of current state, though no changes can be made to
the device configuration.

The ISL9305 and ISL9305H are mini-PMICs offering two DCDC regulators and
two LDO regulators. While there are some register differences between them
these do not affect the current Linux driver as the relevant features are
not yet supported.

Add device-tree support to max1586.
The driver can still be used with the legacy platform data, or the new
device-tree way.
This work is heavily inspired by the device-tree support of its cousin
max8660 driver.

In some cases we need to know when a regulator is about to be changed.
Add a way for clients to be notified. Note that for set_voltage() we
don't necessarily know what voltage we'll end up with, so we tell the
client what the range will be so they can prepare.

The max77802 driver reads the default operating mode (opmode)
set for regulators when enabled from the hardware registers.
But if a regulator is disabled and the system warm restarted,
the hardware reports OFF as the opmode so the regulator is
not enabled. Default to operating mode NORMAL if OFF is read
from the hardware register.

The valid_modes_mask and *dev are not used in this driver, remove them.
Current code uses devm_regulator_register, so we don't need *regulator in

Commit 272e2315fac3 ("regulator: core: add const qualifier to ops in
struct regulator_desc") introduced const qualifier to ops in regulator_desc.
This patch adds 'const' to regulator_ops vars in newly added core APIs
for v3.17-rc1:
- regulator_get_hardware_vsel_register()
- regulator_list_hardware_vsel()
This patch also fix a build error in mc13892-regulator.c due to const
regulator_desc.ops. Modification of regulator_desc.ops' member fields is not
allowed.

Add driver support for HiSilicon Hi6421 voltage regulators.
Two rules for regulator enabling are defined in hi6421 spec:
1) Between disable and enable of each regulator (LDOs or BUCKs), there must
be a protection gap. Use @off_on_delay of regulator core to implement this.
2) No two regulators can be enabled at the same time. Use mutex in
hi6421_regulator_pdata to ensure this. A protection gap of 100us is added
into each LDO/BUCK's .enable_time.

Some regulator require a minimum delay between its disable and next enable.
This is to avoid damages when out-of-range frequent disable/enable of a
single regulator can bring to the regulator chip.
Add @off_on_delay to struct regulator_desc. Device drivers' can use this field
to set this guard time.
Add @last_off_jiffy to struct regulator_dev. When @off_on_delay is set by
driver, regulator core can store its last off (disable) time into this field.

struct regulator_ops *ops is a member in struct regulator_desc, which gets
its value from individual regulator driver upon regulator_register() and
is used by regulator core APIs. It's not allowed for regulator core to

This patch makes the regulator description macro take minimum and
steps voltage as parameter. In this way many repeated macros can be
removed. Now these macros are repeated only if the the LDO/BUCK ctrl
registers have non-linear positions. The good thing is these ctrl registers
are mostly linear so they are not passed as parameters.
This patch reduces the code size and also allow easy addition of more
s2mpxxx PMIC drivers which differs a lot in minimum/step voltages.
