Driver allocates workqueue and then registers additional interrupt
handler with devm interface. This means that device removal will not
use a reversed order, but first destroy workqueue and then, via devm
release handlers, free the interrupt.
The interrupt handler registered with devm does not directly
use/schedule work items on the workqueue and the remove() function
correctly removes other IRQs handlers, however the code mixing devm and
non-devm interfaces is difficult to analyze and read.
Make the code flow much more obvious by using devm interface for
allocating the workqueue, so it will be freed with the rest of devm
resources.
Change is not equivalent in the workqueue itself: use non-legacy API
which does not set (__WQ_LEGACY | WQ_MEM_RECLAIM). The workqueue is
used to update device registers, thus there is no point to run it for
memory reclaim.

Power management blocks across the BCM2835 family share a common
base but require variant-specific handling. For instance, the
BCM2712 lacks ASB register space, yet it manages the power domain
for the V3D graphics block.
Add a hardware type identifier to the driver's private data. This
allows the driver to distinguish between SoC models and implement
custom quirks or features as needed.

take additional references unless the structures are needed after
disconnect.

CIDs set for MT6328, MT6331 and MT6332 are not appropriate.
Many Android downstream kernels define CID as below,
MT6328:
#define PMIC6328_E1_CID_CODE 0x2810
#define PMIC6328_E2_CID_CODE 0x2820
#define PMIC6328_E3_CID_CODE 0x2830
MT6331/MT6332:
#define PMIC6331_E1_CID_CODE 0x3110
#define PMIC6331_E2_CID_CODE 0x3120
#define PMIC6331_E3_CID_CODE 0x3130
#define PMIC6332_E1_CID_CODE 0x3210
#define PMIC6332_E2_CID_CODE 0x3220
#define PMIC6332_E3_CID_CODE 0x3230
The current configuration incorrectly uses the revision code as the CID.
Therefore, the driver cannot detect the same PMIC of different revisions.
(E1/E2 for MT6328, E1/E3 for MT6331/MT6332)
Based on these, the CID of MT6328, MT6331 and MT6332 should be corrected.
Additionally, the incorrect MT6331/MT6332 CID overlaps with the MT6320's
actual CID:
#define PMIC6320_E1_CID_CODE 0x1020
#define PMIC6320_E2_CID_CODE 0x2020
This causes a conflict in the switch-case statement of mt6397-irq.c,
this prevents adding support for MT6320.

One of the users of this driver - meraki-mx100 - abuses the software
node API by setting up a dummy software node without any logical link to
this GPIO controller and uses the fact that the GPIO core matches the
controller's label against the swnode's name to make the lookup work.
We want to remove this behavior from GPIOLIB in favor of actual matching
of firmware nodes but that would break this user. To facilitate that:
create a software node for the GPIO controller cell and expose its
address in the provided MFD header.

The LCD Generic clock (sys_clk) is used for Parallel RGB and MIPI
displays, while the LVDS PLL clock (lvds_pll_clk) is used for LVDS

All the functions operating on the 'handle' pointer are claiming it is a
pointer to const thus they should not modify the handle. In fact that's
a false statement, because first thing these functions do is drop the
cast to const with container_of:
struct acpm_info *acpm = handle_to_acpm_info(handle);
And with such cast the handle is easily writable with simple:
acpm->handle.ops.pmic_ops.read_reg = NULL;
The code is not correct logically, either, because functions like
acpm_get_by_node() and acpm_handle_put() are meant to modify the handle
reference counting, thus they must modify the handle. Modification here
happens anyway, even if the reference counting is stored in the
container which the handle is part of.
The code does not have actual visible bug, but incorrect 'const'
annotations could lead to incorrect compiler decisions.

This converts some of the visually simpler cases that have been split
over multiple lines. I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.
Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script. I probably had made it a bit _too_ trivial.
So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.
The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)

Pull gpio updates from Bartosz Golaszewski:
"There are two new drivers and some changes to GPIO core but mostly
just GPIO driver updates across a wide array of files, adding support
for new models as well as various refactoring changes. Nothing
controversial and everything has spent a good measure of time in
linux-next.
GPIOLIB core:
- shrink the GPIO bus driver stub code
- rework software node support for "undefined" software nodes
- provide and use devm_fwnode_gpiod_get_optional()
- only compile the OF quirk for MT2701 when needed
New drivers:
- add the GPIO driver for ROHM bd72720
- add the gpio-line-mux driver providing 1-to-many mapping for a
single real GPIO
Driver changes:
- refactor gpio-pca9570: use lock guard, add missing headers, use
devres consistently
- add support for a new model (G7 Aspeed sgpiom) to the aspeed-sgpio
driver along with some prerequisite refactoring
- use device_get_match_data() where applicable and save some lines
- add support for more models to gpio-cadence
- add the compatible property to reset-gpio and use it in shared GPIO
management
- drop unnecessary use of irqd_get_trigger_type() in gpio-max77759
- add support for a new variant to gpio-pca953x
- extend build coverage with COMPILE_TEST for more drivers
- constify configfs structures in gpio-sim and gpio-virtuser
- add support for the K3 SoC to gpio-spacemit
- implement the missing .get_direction() callback in gpio-max77620
- add support for Tegra264 to gpio-tegra186
- drop unneeded MODULE_ALIAS() from gpio-menz127
DT bindings:
- document support for the opencores GPIO controller in gpio-mmio
- document new variants for gpio-pca953x

- extensively describe interrupt source detection for gpio-pca953x
and add more models to the list of supported variants"

Add support for Samsung's S2MPG11 PMIC, which is a Power Management IC
for mobile applications with buck converters, various LDOs, power
meters, NTC thermistor inputs, and additional GPIO interfaces. It
typically complements an S2MPG10 PMIC in a main/sub configuration as
the sub-PMIC.
Like S2MPG10, communication is not via I2C, but via the Samsung ACPM
firmware.
While at it, we can also switch to asynchronous probe, which helps with
probe performance, as the drivers for s2mpg10 and s2mpg11 can probe in
parallel.
Note: The firmware uses the ACPM channel ID and the Speedy channel ID
to select the PMIC address. Since these are firmware properties, they
can not be retrieved from DT, but instead are deducted from the
compatible for now.

The mixing of managed and non-managed resources may lead to possible
use-after-free bugs. In this driver the problematic part is the device
functionality that may just have gone behind the functions back, e.g.,
when interrupt is being served. Fix this by switching to managed resources
for PCI.

Since commit c6e126de43e7 ("of: Keep track of populated platform
devices") child devices will not be created by of_platform_populate()
if the devices had previously been deregistered individually so that the
OF_POPULATED flag is still set in the corresponding OF nodes.
Switch to using of_platform_depopulate() instead of open coding so that
the child devices are created if the driver is rebound.
