Commit 99f75ce66619 ("regulator: da9063: fix suspend") converted
the regulators to use a common (corrected) suspend bit setting but
one of regulators (LDO9) slipped through the crack.This means that the original problem was not fixed for LDO9 and
also leads to a warning found by the test robot.
da9063-regulator.c:515:3: warning: initialized field overwrittenFix this by converting that regulator too like the others.

get_mode() is used to retrieve the active mode state. Settings-A
config is used during active state, whilst Settings-B is for
suspend. This means we only need to check the sleep field of each
buck and LDO as that field solely relates to Settings-A config.This change is a clone of the get_mode() update which was committed
as part of:

The .set_suspend_enable() and .set_suspend_disable() methods are not
supposed to immediately change the regulator state but just indicated
if the regulator should be enabled or disabled when standby mode is
entered (by a hardware signal).However currently they set control the SEL bits in the DVC registers,
which causes the voltage to change to immediately between the "A"
(normal) and "B" (standby) values as programmed and does nothing for
the enable state...This means that "regulator-on-in-suspend" does not work (the regulator
is switched off when the PMIC enters standby mode on the hardware
signal) and, potentially, depending on the A and B voltage
configurations the voltage could be incorrectly changed *before*
actually entering suspend.The right bit to use for the functionality is the "CONF" bit in the
"CONT" register.
The detailed register description says "Sequencer target state"
for this bit which is not very clear but the functional description
is clearer.>From 5.1.5 System Enable:
De-asserting SYS_EN (changing from active to passive state)
clears control SYSTEM_EN which triggers a power down sequence
into hibernate/standby mode
...
With the exception of supplies that have the xxxx_CONF control
bit asserted, all regulators in power domains POWER1, POWER, and
SYSTEM are sequentially disabled in reverse order.
Regulators with the _CONF bit set remain on but change the
active voltage controlregisters from V_A to V_B
(if V_B is notalready selected).Signed-off-by: Martin Fuzzey

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:struct foo {
int stuff;
struct boo array[];
};By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertenly introduced[3] to the codebase from now on.This issue was found with the help of Coccinelle.

The mutex for the regulator_dev must be controlled by the caller of
the regulator_notifier_call_chain(), as described in the comment
for that function.Failure to mutex lock and unlock surrounding the notifier call results
in a kernel WARN_ON_ONCE() which will dump a backtrace for the
regulator_notifier_call_chain() when that function call is first made.
The mutex can be controlled using the regulator_lock/unlock() API.Fixes: 69ca3e58d178 ("regulator: da9063: Add Dialog DA9063 voltage regulators support.")

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:struct foo {
int stuff;
struct boo entry[];
};size = sizeof(struct foo) + count * sizeof(struct boo);
instance = alloc(size, GFP_KERNEL)Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:instance = alloc(struct_size(instance, entry, count), GFP_KERNEL)
Notice that, in this case, variable size is not necessary, hence it is
removed.This code was detected with the help of Coccinelle.

The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:devm_kzalloc(handle, a * b, gfp)
with:
devm_kcalloc(handle, a * b, gfp)as well as handling cases of:
devm_kzalloc(handle, a * b * c, gfp)
with:
devm_kzalloc(handle, array3_size(a, b, c), gfp)
as it's slightly less ugly than:
devm_kcalloc(handle, array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
devm_kzalloc(handle, 4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".The Coccinelle script used for this was:

Current code does not set regulators->irq_ldo_lim and regulators->irq_uvov,
so it actually calls free_irq(0, regulators) twice in remove() but does not
free the irq actually used.Convert to use devm_request_threaded_irq instead and then we don't need to
take care the clean up irq so remove irq_ldo_lim and irq_uvov from
struct da9063_regulators. Note, regulators->irq_uvov is not used at all in
current code.There is a slightly change in this patch, it will return error in probe()
if devm_request_threaded_irq fails. If the irq is optional, it should be
fine to allow platform_get_irq_byname fails. But current code does not
allow platform_get_irq_byname fails. So I think the reason to allow
request irq failure is just because the irq leak.Signed-off-by: Axel Lin

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 2The 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.Signed-off-by: Steve Twiss
