The sparse tool complains as follows:
drivers/mfd/arizona-spi.c:28:31: warning:
symbol 'reset_gpios' was not declared. Should it be static?
drivers/mfd/arizona-spi.c:29:31: warning:
symbol 'ldoena_gpios' was not declared. Should it be static?
Those symbols are not used outside of arizona-spi.c, so this
commit marks them static.

Support voltage control for regulators on ROHM BD71815 PMIC.
ROHM BD71815 contains 5 bucks, 7 LDOs and a boost (intended for LED).
Bucks 1 and 2 support HW state based voltage level and enable states. Other
regulators support HW state based enable states. All bucks and LDOs 1-5
allow voltage changes for RUN state and LDO4 can be enabled/disabled via
GPIO.
LDO3 does support changing between two predetermined voltages by using
a GPIO but this functionality is not included in this commit.
This work is derived from driver originally written by Tony Luo
<luofc@embedinfo.com> - although not much of original work is left.

Support GPO(s) found from ROHM BD71815 power management IC. The IC has two
GPO pins but only one is properly documented in the data-sheet. The driver
exposes by default only the documented GPO. The second GPO is connected to
E5 pin and is marked as GND in the data-sheet. Control for this
undocumented pin can be enabled using a special DT property.
This driver is derived from work by Peter Yang <yanglsh@embest-tech.com>
although not so much of the original is left.

Most ROHM PMIC sub-devices only use the regmap pointer from
parent device. They can obtain this by dev_get_regamap so in
most cases the MFD device does not need to allocate and populate
the driver data. Simplify drivers by removing this.
The BD70528 still needs the access to watchdog mutex so keep
rohm_regmap_dev in use on BD70528 RTC and WDG drivers for now.

The ROHM BD71828 and BD71815 RTC drivers only need the regmap
pointer from parent. Regmap can be obtained via dev_get_regmap()
so do not require parent to populate driver data for that.
BD70528 on the other hand requires parent data to access the
watchdog so leave the parent data for BD70528 here for now.

The charging algorithm header is only used locally in the
power supply subsystem so push this down into
drivers/power/supply and rename from the confusing
"ux500_chargalg.h" to "ab8500-chargalg.h" for clarity:
it is only used with the AB8500.
This is another remnant of non-DT code needing to pass

The global definition of platform data for the battery
management code has no utility after the OF conversion,
move the <linux/mfd/abx500/ab8500-bm.h> to be a local
file in drivers/power/supply and stop defining the
platform data in drivers/power/supply/ab8500_bmdata.c
and broadcast to the kernel only to have it assigned
as platform data to the MFD cells and then picked back
into the same subsystem that defined it in the first
place. This kills off a layer of indirection.

The jack handling for arizona codecs is being refactored so that it is
done directly by the codec drivers, instead of having an extcon-driver
bind to a separate "arizona-extcon" child-device for this.
drivers/mfd/arizona-core.c has already been updated to no longer
instantiate an "arizona-extcon" child-device for the arizona codecs.
This means that the "arizona-extcon" driver is no longer useful
(there are no longer any devices for it to bind to).
This commit drops the extcon Kconfig / Makefile bits and moves
drivers/extcon/extcon-arizona.c to sound/soc/codecs/arizona-jack.c .
This is a preparation patch for converting the arizona extcon-driver into
a helper library for letting the arizona codec-drivers directly report jack
state through the standard sound/soc/soc-jack.c functions.

be awake
Before this commit the extcon-arizona code was mixing pm_runtime_get()
and pm_runtime_get_sync() in different places.
In all places where pm_runtime_get[_sync]() is called, the code
makes use of the device immediately after the call.
This means that we should always use pm_runtime_get_sync().

The initial value of the GPIO should match the info->micd_modes[0].gpio
value. arizona_extcon_probe() already stores the necessary flag in a
mode variable, but instead of passing mode as flags to the gpiod_get()
it was using a hardcoded GPIOD_OUT_LOW.

We must free/disable all interrupts and cancel all pending works
before doing further cleanup.
Before this commit arizona_extcon_remove() was doing several
register writes to shut things down before disabling the IRQs
and it was cancelling only 1 of the 3 different works used.
Move all the register-writes shutting things down to after
the disabling of the IRQs and add the 2 missing
cancel_delayed_work_sync() calls.
This fixes various possible races on driver unbind. One of which
would always trigger on devices using the mic-clamp feature for
jack detection. The ARIZONA_MICD_CLAMP_MODE_MASK update was
done before disabling the IRQs, causing:
1. arizona_jackdet() to run
2. detect a jack being inserted (clamp disabled means jack inserted)
3. call arizona_start_mic() which:
3.1 Enables the MICVDD regulator
3.2 takes a pm_runtime_reference
And this was all happening after the ARIZONA_MICD_ENA bit clearing,
which would undo 3.1 and 3.2 because the ARIZONA_MICD_CLAMP_MODE_MASK
update was being done after the ARIZONA_MICD_ENA bit clearing.
So this means that arizona_extcon_remove() would exit with
1. MICVDD enabled and 2. The pm_runtime_reference being unbalanced.
MICVDD still being enabled caused the following oops when the
regulator is released by the devm framework:
[ 2850.745757] ------------[ cut here ]------------
[ 2850.745827] WARNING: CPU: 2 PID: 2098 at drivers/regulator/core.c:2123 _regulator_put.part.0+0x19f/0x1b0

Note this oops is just one of various theoretically possible races caused
by the wrong ordering inside arizona_extcon_remove(), this fixes the
ordering fixing all possible races, including the reported oops.

been unplugged
When the jack is partially inserted and then removed again it may be
removed while the hpdet code is running. In this case the following
may happen:
1. The "JACKDET rise" or ""JACKDET fall" IRQ triggers
2. arizona_jackdet runs and takes info->lock
3. The "HPDET" IRQ triggers
4. arizona_hpdet_irq runs, blocks on info->lock
5. arizona_jackdet calls arizona_stop_mic() and clears info->hpdet_done
6. arizona_jackdet releases info->lock
7. arizona_hpdet_irq now can continue running and:
7.1 Calls arizona_start_mic() (if a mic was detected)
7.2 sets info->hpdet_done
Step 7 is undesirable / a bug:
7.1 causes the device to stay in a high power-state (with MICVDD enabled)
7.2 causes hpdet to not run on the next jack insertion, which in turn
causes the EXTCON_JACK_HEADPHONE state to never get set
This fixes both issues by skipping these 2 steps when arizona_hpdet_irq
runs after the jack has been unplugged.

The arizona jack-dection handling is being reworked so that the
codec-child-device drivers directly handle jack-detect themselves,
so it is no longer necessary to instantiate "arizona-extcon"
child-devices.

The tegra_smmu_probe_device() handles only the first IOMMU device-tree
phandle, skipping the rest. Devices like 3D module on Tegra30 have
multiple IOMMU phandles, one for each h/w block, and thus, only one
IOMMU phandle is added to fwspec for the 3D module, breaking GPU.
Previously this problem was masked by tegra_smmu_attach_dev() which
didn't use the fwspec, but parsed the DT by itself. The previous commit
to tegra-smmu driver partially reverted changes that caused problems for
T124 and now we have tegra_smmu_attach_dev() that uses the fwspec and
the old-buggy variant of tegra_smmu_probe_device() which skips secondary
IOMMUs.
Make tegra_smmu_probe_device() not to skip the secondary IOMMUs. This
fixes a partially attached IOMMU of the 3D module on Tegra30 and now GPU
works properly once again.

The amd_iommu_irq_remap variable is set to true in amd_iommu_prepare().
But if initialization fails it is not set to false. Fix that and
correctly keep track of whether irq remapping is enabled or not.
