Each iteration of for_each_child_of_node puts the previous node, but in
the case of a return from the middle of the loop, there is no put, thus
causing a memory leak. Hence add an of_node_put before the return in
two places.
Issue found with Coccinelle.

We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.
// <smpl>

expression ret;
struct platform_device *E;

ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)

-{ ...
-dev_err(...);
-... }

-dev_err(...);

// </smpl>
While we're here, remove braces on if statements that only have one

The local variable search in regulator_of_get_init_node takes the value
returned by either of_get_child_by_name or of_node_get, both of which
get a node. If this node is not put before returning, it could cause a
memory leak. Hence put search before a mid-loop return statement.

According to the datasheet http://www.ti.com/lit/ds/symlink/lm36274.pdf:
Table 23. VPOS Bias Register Field Descriptions VPOS[5:0]:
VPOS voltage (50-mV steps): VPOS = 4 V + (Code × 50 mV), 6.5 V max
000000 = 4 V
000001 = 4.05 V
:
011110 = 5.5 V (Default)
:
110010 = 6.5 V
110011 to 111111 map to 6.5 V
So the LM36274_LDO_VSEL_MAX should be 0b110010 (0x32).
The valid selectors are 0 ... LM36274_LDO_VSEL_MAX, n_voltages should be
LM36274_LDO_VSEL_MAX + 1. Similarly, the n_voltages should be
LM36274_BOOST_VSEL_MAX + 1 for LM36274_BOOST.

Refactoring of axp20x driver introduced a bug in AXP803's DCDC6
regulator definition. AXP803_DCDC6_1120mV_STEPS was obtained by
subtracting 0x47 and 0x33. This should be 0x14 (hex) and not 14
(dec).
Refactoring also carried over a bug in DCDC5 regulator definition.
Number of possible voltages must be for 1 bigger than maximum valid
voltage index, because 0 is also valid and it means lowest voltage.

Refactoring of the driver introduced bugs in AXP806's DCDCA and DCDCD
regulator definitions.
In DCDCA case, AXP806_DCDCA_1120mV_STEPS was obtained by subtracting
0x47 and 0x33. This should be 0x14 (hex) and not 14 (dec).
In DCDCD case, axp806_dcdcd_ranges[] contains two ranges with same
start and end macros, which is clearly wrong. Second range starts at
1.6V so it should use AXP806_DCDCD_1600mV_[START|END] macros. They are
already defined but unused.

devices, that can be used to supply ADC analog input switches.

The driver was registering buck regulators with unsupported range of
voltages for S2MPS11 devices. Basically it assumed that all 256 values
are possible for a single 8-bit I2C register controlling buck's voltage.
This is not true, as datasheet describes subset of these which can be
used.
For example for buck[12346] the minimum voltage is 650 mV which
corresponds to register value of 0x8. The driver was however
registering regulator starting at 600 mV, so for a step of 6.25 mV this
gave the same result. However this allowed to try to configure
regulators to unsupported values.

On S2MPS11 device, the buck7 and buck8 regulator voltages start at 750
mV, not 600 mV. Using wrong minimal value caused shifting of these
regulator values by 150 mV (e.g. buck7 usually configured to v1.35 V was
reported as 1.2 V).
On most of the boards these regulators are left in default state so this
was only affecting reported voltage. However if any driver wanted to
change them, then effectively it would set voltage 150 mV higher than
intended.

In case the requested gpio property is not found in the device tree, some
callers of gpiod_get_from_of_node() expect a return value of NULL, others
expect -ENOENT.
In particular devm_fwnode_get_index_gpiod_from_child() expects -ENOENT.
Currently it gets a NULL, which breaks the loop that tries all
gpio_suffixes. The result is that a gpio property is not found, even
though it is there.
This patch changes gpiod_get_from_of_node() to return -ENOENT instead
of NULL when the requested gpio property is not found in the device
tree. Additionally it modifies all calling functions to properly
evaluate the return value.
Another approach would be to leave the return value of
gpiod_get_from_of_node() as is and fix the bug in
devm_fwnode_get_index_gpiod_from_child(). Other callers would still need
to be reworked. The effort would be the same as with the chosen solution.

Low-voltage switches (lvs) don't have set_points since the voltage ranges
of the output are really controlled by the inputs. This is a problem for
the newly added linear range support in the probe(), as that will cause
a null pointer dereference error on older platforms like msm8974 which
happen to need to control some of the implemented lvs.
Fix this by adding the appropriate null check.

spmi_regulator_set_voltage_time_sel() calculates the amount of delay
needed as the result of setting a new voltage. Essentially this is the
absolute difference of the old and new voltages, divided by the slew rate.
The implementation of spmi_regulator_set_voltage_time_sel() is wrong.
It attempts to calculate the difference in voltages by using the
difference in selectors and multiplying by the voltage step between
selectors. This ignores the possibility that the old and new selectors
might be from different ranges, which have different step values. Also,
the difference between the selectors may encapsulate N ranges inbetween,
so a summation of each selector change from old to new would be needed.
Lets avoid all of that complexity, and just get the actual voltage
represented by both the old and new selector, and use those to directly
compute the voltage delta. This is more straight forward, and has the
side benifit of avoiding issues with regulator implementations that don't
have hardware register support to get the current configured range.

According to the DA9061 and DA9062 datasheets the LDO voltage selection
registers have a lower value of 0x02. This applies to voltage registers
VLDO1_A, VLDO2_A, VLDO3_A and VLDO4_A. This linear offset of 0x02 was
previously not observed by the driver, causing the LDO output voltage to
be systematically lower by two steps (= 0.1V).
This patch fixes the minimum linear selector offset by setting it to a
value of 2 and increases the n_voltages by the same amount allowing
voltages in the range 0x02 -> 0.9V to 0x38 -> 3.6V to be correctly
selected. Also fixes an incorrect calculaton for the n_voltages value in
the regulator LDO2.
These fixes effect all LDO regulators for DA9061 and DA9062.

If devm_gpiod_get_from_of_node() call returns ERR_PTR, it is assigned
into an array of GPIO descriptors and used later because such error is
not treated as critical thus it is not propagated back to the probe

All code later expects that such GPIO descriptor is either a NULL or
proper value. This later might lead to dereference of ERR_PTR.
Only devices with S2MPS14 flavor are affected (other do not control

This finalizes the descriptor conversion of the MAX8952 driver
by letting the VID0 and VID1 GPIOs be fetched from descriptors.
Both VID0 and VID1 must be supplied for the VID selection to work,
I add some code to preserve the semantics that if only one of
the two VID gpios is supplied, it will be initialized to low.
This might be a bit overzealous, but I want to preserve any
implicit semantics.
This is currently only used by device tree in-kernel but it is
still also possible to supply the same GPIOs using a machine
descriptor table if a board file is used.
Ideally this should be phased over to using gpio-regulator.c
that does the same thing, but it might require some refactoring
and needs testing on real hardware.

Lockdep reports the following issue on my setup:
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock((work_completion)(&(&rdev->disable_work)->work));
lock(regulator_list_mutex);
lock((work_completion)(&(&rdev->disable_work)->work));
lock(regulator_list_mutex);
The problem is that regulator_unregister takes the
regulator_list_mutex and then calls flush_work on disable_work. But
regulator_disable_work calls regulator_lock_dependent which will
also take the regulator_list_mutex. Resulting in a deadlock if the
flush_work call actually needs to flush the work.
Fix this issue by moving the flush_work outside of the
regulator_list_mutex. The list mutex is not used to guard the point at
which the delayed work is queued, so its use adds no additional safety.

During several error paths in the function
regulator_set_voltage_unlocked() the value of 'ret' can take on negative
error values. However, in calls that go through the 'goto out' statement,
this return value is lost and return 0 is used instead, indicating a
'pass'.
There are several cases where this function should legitimately return a
fail instead of a pass: one such case includes constraints check during
voltage selection in the call to regulator_check_voltage(), which can
have -EINVAL for the case when an unsupported voltage is incorrectly
requested. In that case, -22 is expected as the return value, not 0.

changes to fix up the merge issue -- broonie]
commit e5e21f70bf ("regulator: core: Take lock before applying system
load") took the regulator lock before calling drms_uA_update() in order
to silence a lockdep warning during regulator_register().
However, we are not supposed to need locks at this point as the regulator
is in the process of being registered, so there should be no possibility
of concurrent access.
Instead, remove the unnecessary locking and simply drop the lockdep
annotation, since it is no longer valid.
