Lee Jones 4a5d301328 regulator: Add new driver for ST's PWM controlled voltage regulators
On some STMicroelectronics hardware reside regulators consisting
partly of a PWM input connected to the feedback loop. As the PWM
duty-cycle is varied the output voltage adapts. This driver
allows us to vary the output voltage by adapting the PWM input
duty-cycle.

Axel Lin 114c5748d5 regulator: anatop: Remove checking control_reg in [set|get]_voltage_sel
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.

Carlo Caione ca5d1b3524 regulator: helpers: Modify helpers enabling multi-bit control
This patch extends the regulator helpers to account for device that use
multiple bits for control when using regmap enable/disable/bypass ops.

The actual regulator helpers wrongly assume that the regulator control
is always performed using single bits, using in the regulator_desc
struct only two parameters *_reg and *_mask defining register and mask
for control.

This patch extends this struct and introduces the helpers to take into
account devices where control is performed using multiple bits and
specific multi-bit values are used for enabling/disabling/bypassing the
regulator.

Krzysztof Kozlowski 0f4cc28295 regulator: s2mps11: Fix section mismatch
Remove __initconst from regulator_desc array because this array is used
during probe and s2mps11_pmic_probe() is not in __init section. However
still select the number of supported regulators according to device ID
so the driver will be ready for adding support for S2MPS14 device.

Krzysztof Kozlowski 3e80f95bfc regulator: s2mps11: Copy supported regulators from initconst
Add __initconst to 'regulator_desc' array with supported regulators.
During probe choose how many and which regulators will be supported
according to device ID. Then copy the 'regulator_desc' array to
allocated memory so the regulator core can use it.

Additionally allocate array of of_regulator_match() dynamically (based
on number of regulators) instead of allocation on the stack.

This is needed for supporting different devices in s2mps11
driver and actually prepares the regulator driver for supporting the
S2MPS14 device.

Code for supporting the S2MPS14 device will add its own array of
'regulator_desc' (also marked as __initconst). This way memory footprint
of the driver will be reduced (approximately 'regulators_desc' array for
S2MPS11 occupies 5 kB on 32-bit ARM, for S2MPS14 will occupy 3 kB).

Markus Pargmann 66fda75f47 regulator: core: Replace direct ops->disable usage
There are many places where ops->disable is called directly. Instead we
should use _regulator_do_disable() which also handles gpio regulators.

To be able to use the wrapper function from _regulator_force_disable(),
I moved the _notifier_call_chain() call from _regulator_do_disable() to
_regulator_disable(). This way, _regulator_force_disable() can use
different flags for _notifier_call_chain() without calling it twice.

Markus Pargmann 30c2197103 regulator: core: Replace direct ops->enable usage
There are some direct ops->enable in the regulator core driver. This is
a potential issue as the function _regulator_do_enable() handles gpio
regulators and the normal ops->enable calls. These gpio regulators are
simply ignored when ops->enable is called directly.

One possible bug is that boot-on and always-on gpio regulators are not
enabled on registration.

This patch replaces all ops->enable calls by _regulator_do_enable.

Open coding the counting of elements in a dt-property is abstracted by the newly
introduced of_property_count_uXX_elems functions. Additionally the raw iteration
over the states element exposes the endian conversion and dtb-format details,
which according to Mark Rutland "would be nice to limit [...] to of_ helper
functions".

Thus change ti-abb-regulator to use the helper for element counting and
of_property_read_u32_index for retrieval of individual values.

This makes it possible to remove the raw access to the property entirely.

Steve Twiss ebf6dad0de regulator: da9063: Bug fix when setting max voltage on LDOs 5-11
Bug fix to allow the setting of maximum voltage for certain LDOs.

What the bug is:

There is a problem caused by an invalid calculation of n_voltages
in the driver. This n_voltages value has the potential to be
different for each regulator.

The value for linear_min_sel is set as DA9063_V##regl_name#
which can be different depending upon the regulator. This is
chosen according to the following definitions in the DA9063
registers.h file:

DA9063_VLDO1_BIAS	0
DA9063_VLDO2_BIAS	0
DA9063_VLDO3_BIAS	0
DA9063_VLDO4_BIAS	0
DA9063_VLDO5_BIAS	2
DA9063_VLDO6_BIAS	2
DA9063_VLDO7_BIAS	2
DA9063_VLDO8_BIAS	2
DA9063_VLDO9_BIAS	3
DA9063_VLDO10_BIAS	2
DA9063_VLDO11_BIAS	2

The calculation for n_voltages is valid for LDOs whose BIAS value
is zero but this is not correct for those LDOs which have a
non-zero value.

What the fix is:

In order to take into account the non-zero linear_min_sel value which
is set for the regulators LDO5, LDO6, LDO7, LDO8, LDO9, LDO10 and
LDO11, the calculation for n_voltages should take into account the
missing term defined by DA9063_V##regl_name#.

This will in turn allow the core constraints calculation to set the
maximum voltage limits correctly and therefore allow users to apply
the maximum expected voltage to all of the LDOs.

Nishanth Menon 6127daa850 regulator: ti-abb: Add support for interleaved LDO registers
Certain platforms such as DRA7 have quirky memory maps such as:
PRM_ABBLDO_DSPEVE_CTRL	0x4ae07e20
PRM_ABBLDO_IVA_CTRL	0x4ae07e24
other-registers
PRM_ABBLDO_DSPEVE_SETUP	0x4ae07e30
PRM_ABBLDO_IVA_SETUP	0x4ae07e34

These need the address range allocation to be either not reserved OR
unique allocation per register instance or use something like syscon
based solution.

By going with unique allocation per register, we are able to now have
a single compatible driver for all instances on all platforms which
use the IP block.

So, introduce a new "ti,abb-v3" compatible to allow for definitions
where explicit register definitions are provided, while maintaining
backward compatibility of older predefined register offsets provided
by "ti-abb-v1" and "ti-abb-v2".

As part of this change, we rename a few variables to indicate the
appropriate meaning.

the regulator API. This means that we should treat failed lookups as fatal
rather than deferring in the hope of further registrations but this was
broken by commit 9b92da1f12 "regulator: core: Fix default return
value for _get()" which was targeted at DT systems but unintentionally
broke non-DT systems by changing the default return value.

Fix this by explicitly returning -EPROBE_DEFER from the DT lookup if we
find a property but no corresponding regulator and by having the non-DT
case default to -ENODEV when we have full constraints.

Fixes: 9b92da1f12 "regulator: core: Fix default return value for _get()"

Krzysztof Kozlowski ee1e0994ab regulator: s5m8767: Use GPIO for controlling Buck9/eMMC
Add support for GPIO control (enable/disable) over Buck9. The Buck9
Converter is used as a supply for eMMC Host Controller.

BUCK9EN GPIO of S5M8767 chip may be used by application processor to
enable or disable the Buck9. This has two benefits:
 - It is faster than toggling it over I2C bus.
 - It allows disabling the regulator during suspend to RAM; The AP will
   enable it during resume; Without the patch the regulator supplying
   eMMC must be defined as fixed-regulator.

Linus Torvalds 15333539a9 regulator: Updates for v3.14
A respin of the merges in the previous pull request with one extra fix.
 A quiet release for the regulator API, quite a large number of small
 improvements all over but other than the addition of new drivers for the
 AS3722 and MAX14577 there is nothing of substantial non-local impact.

The AB3100 regulator driver emits a warning when compiled on 64bit
systems like this:

In function ‘ab3100_regulator_of_probe’:
srivers/regulator/ab3100.c:649:4:
warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]

As the int is a different size than the 64bit pointer used to
pass regulator data. Switch to using an unsigned long as ID
passed for the regulator to get rid of the warning.

Stefan Agner 844a4f0d8a regulator: tps6586x: Add and use correct voltage table
Depending on the regulator version, the voltage table might be
different. Use version specific regulator tables in order to select
correct voltage table. For the following regulator versions different
voltage tables are now used:

  * TPS658623: Use correct voltage table for SM2
  * TPS658643: New voltage table for SM2

Both versions are in use on the Colibri T20 module. Make use of the
correct tables by requesting the correct SM2 voltage of 1.8V.

This change is not backward compatible since an old driver is not able
to correctly set that value. The value 1.8V is out of range for the old
driver and will refuse to probe the device. The regulator starts with
default settings and the driver shows appropriate error messages.

On Colibri T20, the old value used to work with TPS658623 since the
driver applied a wrong voltage table too. However, the TPS658643 used
on V1.2 devices uses yet another voltage table and those broke that
pseudo-compatibility. The regulator driver now has the correct voltage
table for both regulator versions and those the correct voltage can be
used in the device tree.
