87ea8c7e2d mfd: ipaq-micro: Remove unused variable i in micro_rx_msg()
There is a warning reported by kernel test robot:

drivers/mfd/ipaq-micro.c:81:6: warning: unused variable ‘i’ [-Wunused-variable]

Since the commit 92d82d76c842 ("mfd: ipaq-micro: Use %*ph for printing
hexdump of a small buffer"), the variable 'i' is unused. Remove it to
silence the warning.

70d39151e0 dt-bindings: mfd: st,stpmic1: Merge patterns for nodes
Properties should be described only once, thus having separate pattern
for children just to specify the $ref to regulator.yaml is not correct.
It also makes impossible to finish it with
additional/unevaluatedProperties:false to restrict allowed properties in
regulator node.

Merge the patterns, so each regulator subnode has regulator.yaml $ref,
additional properties and ends with additionalProperties:false.  This
points to missing regulator-min/max-microvolt in LDO4 node.

Add micro-USB connector under "muic" node to properly represent the

"muic" (this is max77693, so there is no need to state it in its child
nodes).  This "muic" node is used only to instantiate MUIC driver by
compatible, thus actual Linux driver changes are needed.  Extend the

10d3340441 mfd: rz-mtu3: Link time dependencies
The new set of drivers for RZ/G2L MTU3a tries to enable compile-testing the
individual client drivers even when the MFD portion is disabled but gets it
wrong, causing a link failure when the core is in a loadable module but the
other drivers are built-in:

x86_64-linux-ld: drivers/pwm/pwm-rz-mtu3.o: in function `rz_mtu3_pwm_apply':
pwm-rz-mtu3.c:(.text+0x4bf): undefined reference to `rz_mtu3_8bit_ch_write'
x86_64-linux-ld: pwm-rz-mtu3.c:(.text+0x509): undefined reference to `rz_mtu3_disable'

arm-linux-gnueabi-ld: drivers/counter/rz-mtu3-cnt.o: in function `rz_mtu3_cascade_counts_enable_get':
rz-mtu3-cnt.c:(.text+0xbec): undefined reference to `rz_mtu3_shared_reg_read'

It seems better not to add the extra complexity here but instead just use
a normal hard dependency, so remove the #else portion in the header along
with the "|| COMPILE_TEST". This could also be fixed by having slightly more
elaborate Kconfig dependencies or using the cursed 'IS_REACHABLE()' helper,
but in practice it's already possible to compile-test all these drivers
by enabling the mtd portion.

f1a63db65e mfd: qcom-pm8xxx: Fix potential deadlock on &chip->pm_irq_lock
As &chip->pm_irq_lock is acquired by pm8xxx_irq_handler() under irq
context, other process context code should disable irq before acquiring
the lock.

Since .irq_set_type and .irq_get_irqchip_state callbacks are generally
executed from process context without irq disabled by default, the same
lock acquision should disable irq.

Possible deadlock scenario
pm8xxx_irq_set_type()
    -> pm8xxx_config_irq()
    -> spin_lock(&chip->pm_irq_lock)
        <irq interrupt>
        -> pm8xxx_irq_handler()
        -> pm8xxx_irq_master_handler()
        -> pm8xxx_irq_block_handler()
        -> pm8xxx_read_block_irq()
        -> spin_lock(&chip->pm_irq_lock) (deadlock here)

This flaw was found using an experimental static analysis tool we are
developing for irq-related deadlock.

Fix the potential deadlock by spin_lock_irqsave().

dc0c386e09 mfd: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

4ffee2918d mfd: cs47l15: Update to use maple tree register cache
The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.

Update the cs47l15 driver to use the more modern data structure.

Cleanup bindings dropping unneeded quotes. Once all these are fixed,
checking for this can be enabled in yamllint.  Also absolute path
starting with /schemas is preferred.

e10038ce1b dt-bindings: mfd: Convert STMPE to YAML schema
This converts the STMPE MFD device tree bindings to the YAML
schema.

Reference the existing schema for the ADC, just define the
other subnode schemas directly in the MFD schema.

Add two examples so we have examples covering both the simple
GPIO expander and the more complex with ADC and touchscreen.

Some in-tree users do not follow the naming conventions for nodes
so these DTS files need to be augmented to use proper node names
like "adc", "pwm", "gpio", "keyboard-controller" etc before the
bindings take effect on them.
