6a24f567af mfd: syscon: Add arguments support for syscon reference
There are a lot of similar global registers being used across multiple SoCs
from Unisoc. But most of these registers are assigned with different offset
for different SoCs. It is hard to handle all of them in an all-in-one
kernel image.

Add a helper function to get regmap with arguments where we could put some
extra information such as the offset value.

Few ROHM PMICs allow setting the voltage states for different system states
like RUN, IDLE, SUSPEND and LPSR. States are then changed via SoC specific
mechanisms. bd718x7 driver implemented device-tree parsing functions for
these state specific voltages. The parsing functions can be re-used by
other ROHM chip drivers like bd71828. Split the generic functions from
bd718x7-regulator.c to rohm-regulator.c and export them for other modules

Do device matching using the platform_device_id instead of using
explicit module_aliases to load modules and custom parent-data field

11f1eabee0 cros_ec: treewide: Remove 'include/linux/mfd/cros_ec.h'
This header file now only includes the cros_ec_dev struct, however, is the
'include/linux/platform_data/cros_ec_proto.h' who contains the definition of
all the Chrome OS EC related structs. There is no reason to have a
separate include for this struct so move to the place where other
structs are defined. That way, we can remove the include itself, but also
simplify the common pattern

    #include <linux/mfd/cros_ec.h>
    #include <linux/platform_data/cros_ec_proto.h>

for a single include

    #include <linux/platform_data/cros_ec_proto.h>

The changes to remove the cros_ec.h include were generated with the
following shell script:

    git grep -l "<linux/mfd/cros_ec.h>" | xargs sed -i '/<linux\/mfd\/cros_ec.h>/d'

22fb3ad0cc mfd: db8500-prcmu: Support U8420-sysclk firmware
There is a distinct version of the Ux500 U8420 variant
with "sysclk", as can be seen from the vendor code that
didn't make it upstream, this firmware lacks the
ULPPLL (ultra-low power phase locked loop) which in
effect means that the timer clock is instead wired to
the 32768 Hz always-on clock.

This has some repercussions when enabling the timer
clock as the code as it stands will disable the timer
clock on these platforms (lacking the so-called
"doze mode") and obtaining the wrong rate of the timer
clock.

The timer frequency is of course needed very early in
the boot, and as a consequence, we need to shuffle
around the early PRCMU init code: whereas in the past
we did not need to look up the PRCMU firmware version
in the early init, but now we need to know the version
before the core system timers are registered so we
restructure the platform callbacks to the PRCMU so as
not to take any arguments and instead look up the
resources it needs directly from the device tree
when initializing.

As we do not yet support any platforms using this
firmware it is not a regression, but as PostmarketOS
is starting to support products with this firmware we
need to fix this up.

The low rate of 32kHz also makes the MTU timer unsuitable
as delay timer but this needs to be fixed in a separate
patch.

The MFD implementation for reference counting was complex and unnecessary.
There was only one bona fide user which has now been converted to handle
the process in a different way. Any future resource protection, shared

through the MFD subsystem API.

Providing a subsystem-level API helper seems over-kill just to save a

a77fc11156 mfd: Switch the AB8500 GPADC to IIO
The AB8500 GPADC driver is indeed a "general purpose ADC" driver,
and while the IIO subsystem did not exist when the driver was
first merged, it is never too late to clean things up and move it
to the right place.

Nowadays IIO provides the right abstractions and interfaces to
do generic ADC work in the kernel.

We have to cut a bunch of debugfs luggage to make this transition
swift, but all these files to is read out the raw values of the
ADC and the IIO subsystem already has a standard sysfs ABI for
doing exactly this: no debugfs is needed.

840d9f131f mfd / platform: cros_ec: Reorganize platform and mfd includes
There is a bit of mess between cros-ec mfd includes and platform
includes. For example, we have a linux/mfd/cros_ec.h include that
exports the interface implemented in platform/chrome/cros_ec_proto.c. Or
we have a linux/mfd/cros_ec_commands.h file that is non related to the
multifunction device (in the sense that is not exporting any function of
the mfd device). This causes crossed includes between mfd and
platform/chrome subsystems and makes the code difficult to read, apart
from creating 'curious' situations where a platform/chrome driver includes
a linux/mfd/cros_ec.h file just to get the exported functions that are
implemented in another platform/chrome driver.

In order to have a better separation on what the cros-ec multifunction
driver does and what the cros-ec core provides move and rework the
affected includes doing:

 - Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h
 - Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c
   driver from include/linux/mfd/cros_ec.h to a new file
   include/linux/platform_data/cros_ec_proto.h
 - Update all the drivers with the new includes, so
   - Drivers that only need to know about the protocol include
     - linux/platform_data/cros_ec_proto.h
     - linux/platform_data/cros_ec_commands.h
   - Drivers that need to know about the cros-ec mfd device also include
     - linux/mfd/cros_ec.h

7aa703bb88 mfd / platform: cros_ec: Handle chained ECs as platform devices
An MFD is a device that contains several sub-devices (cells). For instance,
the ChromeOS EC fits in this description as usually contains a charger and
can have other devices with different functions like a Real-Time Clock,
an Audio codec, a Real-Time Clock, ...

If you look at the driver, though, we're doing something odd. We have
two MFD cros-ec drivers where one of them (cros-ec-core) instantiates
another MFD driver as sub-driver (cros-ec-dev), and the latest
instantiates the different sub-devices (Real-Time Clock, Audio codec,
etc).

                  MFD
------------------------------------------
   cros-ec-core
       |___ mfd-cellA (cros-ec-dev)
       |       |__ mfd-cell0
       |       |__ mfd-cell1
       |       |__ ...
       |
       |___ mfd-cellB (cros-ec-dev)
               |__ mfd-cell0
               |__ mfd-cell1
               |__ ...

The problem that was trying to solve is to describe some kind of topology for
the case where we have an EC (cros-ec) chained with another EC
(cros-pd). Apart from that this extends the bounds of what MFD was
designed to do we might be interested on have other kinds of topology that
can't be implemented in that way.

Let's prepare the code to move the cros-ec-core part from MFD to
platform/chrome as this is clearly a platform specific thing non-related
to a MFD device.

  platform/chrome  |         MFD

Add an MFD driver for Intel Merrifield Basin Cove PMIC.

Firmware on the platforms which are using Basin Cove PMIC is "smarter"
than on the rest supported by vanilla kernel. It handles first level
of interrupt itself, while others do it on OS level.

The driver is done in the same way as the rest of Intel PMIC MFD drivers
in the kernel to support the initial design. The design allows to use
one driver among few PMICs without knowing implementation details of
the each hardware version or generation.

mfd/syscon: Add device_node_to_regmap()
device_node_to_regmap() is exactly like syscon_node_to_regmap(), but it
does not check that the node is compatible with "syscon", and won't
attach the first clock it finds to the regmap.

The rationale behind this, is that one device node with a standard
compatible string "foo,bar" can be covered by multiple drivers sharing a
regmap, or by a single driver doing all the job without a regmap, but
these are implementation details which shouldn't reflect on the
devicetree.

return value.  The function can work or not, but the code logic should
never do something different based on this.

f632a8170a Driver Core and debugfs changes for 5.3-rc1
Here is the "big" driver core and debugfs changes for 5.3-rc1
 
 It's a lot of different patches, all across the tree due to some api
 changes and lots of debugfs cleanups.  Because of this, there is going
 to be some merge issues with your tree at the moment, I'll follow up
 with the expected resolutions to make it easier for you.
 
 Other than the debugfs cleanups, in this set of changes we have:
 	- bus iteration function cleanups (will cause build warnings
 	  with s390 and coresight drivers in your tree)
 	- scripts/get_abi.pl tool to display and parse Documentation/ABI
 	  entries in a simple way
 	- cleanups to Documenatation/ABI/ entries to make them parse
 	  easier due to typos and other minor things
 	- default_attrs use for some ktype users
 	- driver model documentation file conversions to .rst
 	- compressed firmware file loading
 	- deferred probe fixes
 
 All of these have been in linux-next for a while, with a bunch of merge
 issues that Stephen has been patient with me for.  Other than the merge
 issues, functionality is working properly in linux-next :)
