The rest are all small fixes and/or quirks.

Currently the I2C device Ids conflict for the MFD and CODEC so
cannot be both instantiated on one platform. This patch updates
the Ids and names to make them unique from each other.
It should be noted that the I2C addresses for both PMIC and CODEC
are modifiable so instantiation of the two are kept as separate
devices, rather than instantiating the CODEC from the MFD code.

The MUIC block in max77693 has different I2C address than PMIC. The
driver allocated two regmaps: for PMIC and MUIC. However it used the
same regmap_config (with max_register field) for both regmaps. Actual
maximum address of register for MUIC is different than for PMIC.
Define another regmap_config for MUIC with proper max_register value.

The regmap used by max77686 MFD driver was not freed with regmap_exit()

management code.

mfd_add_device() assigns .of_node in the device objects it creates only
if the mfd_cell for the device has the .of_compatible field set and the
DT node for the top-level MFD device contains a child whose compatible
property matches the cell's .of_compatible field.
This leaves .of_node unset in many cases. When this happens, entries in
the DT /aliases property which refer to the top-level MFD DT node will
never match the MFD child devices, hence causing the requested alias not
to be honored.
Solve this by setting each MFD child device's .of_node equal to the top-
level MFD device's .of_node field in the cases where it would otherwise
remain unset.
The first use-case for this will be aliases for the TPS6586x's RTC
device.

The EC has specific timing it requires. Add support for an optional delay
after raising CS to fix timing issues. This is configurable based on
a DT property "google,cros-ec-spi-msg-delay".

The driver should check whether requested pin is available or not.
If the pin is already used, pin request returns as a failure.
A driver data, 'pin_used' is checked when gpio_request() and
pwm_request() are called. If the pin is available, then pin_used is set.
And it is cleared when gpio_free() and pwm_free().

Add PM suspend/resume ops to the sec MFD core driver and make it a wake

broken interrupts after resuming:
[ 42.705703] sec_pmic 7-0066: Failed to read IRQ status: -5
Interrupts stop working after first resume initiated by them (e.g. by
RTC Alarm interrupt) because interrupt registers were not cleared properly.
When device is woken up from suspend by RTC Alarm, an interrupt occurs
before resuming I2C bus controller. The interrupt is handled by
regmap_irq_thread which tries to read RTC registers. This read fails
(I2C is still suspended) and RTC Alarm interrupt is disabled.
Disable the S5M8767 interrupts during suspend (disable_irq()) and enable
them during resume so the device will be still woken up but the interrupt
won't happen before resuming I2C bus.

If the regcache is enabled on the regmap module drivers might need to access
to HW register(s) in certain cases in cache bypass mode.
As an example of this is the audio block's ANAMICL register. In normal
operation the content can be cached but during initialization one bit from
the register need to be monitored. With the twl_set_regcache_bypass() the
client driver can switch regcache bypass on and off when it is needed so
we can utilize the regcache for more registers.

The ADC driver always programs all possible ADC values and discards
them except for the value IIO asked for. On the am335x-evm the driver
programs four values and it takes 500us to gather them. Reducing the number
of conversations down to the (required) one also reduces the busy loop down
to 125us.
This leads to another error, namely the FIFOCOUNT register is sometimes
(like one out of 10 attempts) not updated in time leading to EBUSY.
The next read has the FIFOCOUNT register updated.
Checking for the ADCSTAT register for being idle isn't a good choice either.
The problem is that if TSC is used at the same time, the HW completes the
conversation for ADC *and* before the driver noticed it, the HW begins to
perform a TSC conversation and so the driver never seen the HW idle. The
next time we would have two values in the FIFO but since the driver reads
everything we always see the current one.
So instead of polling for the IDLE bit in ADCStatus register, we should
check the FIFOCOUNT register. It should be one instead of zero because we
request one value.
This change in turn leads to another error. Sometimes if TSC & ADC are
used together the TSC starts generating interrupts even if nobody
actually touched the touchscreen. The interrupts seem valid because TSC's
FIFO is filled with values for each channel of the TSC. This condition stops
after a few ADC reads but will occur again. Not good.
On top of this (even without the changes I just mentioned) there is a ADC
& TSC lockup condition which was reported to me by Jeff Lance including the
following test case:
A busy loop of "cat /sys/bus/iio/devices/iio\:device0/in_voltage4_raw"
and a mug on touch screen. With this setup, the hardware will lockup after
something between 20 minutes and it could take up to a couple of hours.
During that lockup, the ADCSTAT register says 0x30 (or 0x70) which means
STEP_ID = IDLE and FSM_BUSY = yes. That means the hardware says that it is
idle and busy at the same time which is an invalid condition.
For all this reasons I decided to rework this TSC/ADC part and add a
handshake / synchronization here:
First the ADC signals that it needs the HW and writes a 0 mask into the
SE register. The HW (if active) will complete the current conversation
and become idle. The TSC driver will gather the values from the FIFO
(woken up by an interrupt) and won't "enable" another conversation.
Instead it will wake up the ADC driver which is already waiting. The ADC
driver will start "its" conversation and once it is done, it will
enable the TSC steps so the TSC will work again.
After this rework I haven't observed the lockup so far. Plus the busy
loop has been reduced from 500us to 125us.
The continues-read mode remains unchanged.

The purpose of reg_se_cache has been defeated. It should avoid the
read-back of the register to avoid the latency and the fact that the
bits are reset to 0 after the individual conversation took place.
The reason why this is required like this to work, is that read-back of
the register removes the bits of the ADC so they do not start another
conversation after the register is re-written from the TSC side for the
update.
To avoid the not required read-back I introduce a "set once" variant which
does not update the cache mask. After the conversation completes, the
bit is removed from the SE register anyway and we don't plan a new
conversation "any time soon". The current set function is renamed to
set_cache to distinguish the two operations.
This is a small preparation for a larger sync-rework.

Lots of driver updates here plus some nice new core features, the main
one being the first:
- Enable support for providing a dummy regulator when we know that one
must exist for the device to be functional. This makes it much
easier to add regulator support to drivers since we don't require
that the machine integration for all systems using the device be
updated to provide regulators.
- Substantial reduction in the amount of busy waiting done while
waiting for enables to complete.
- Allow MFDs to distribute regulator supplies to child devices so we
don't have to expose the internal structure of MFDs outside of the
driver.
- Managed registeration for regulators.

If the first call to mfd_add_device() fails, no child devices have been
registered to the parent yet, and thus mfd_remove_devices() won't find
anything to remove nor free.
Hence the previously allocated array of atomic_t objects will leak.
Free the array instead of calling mfd_remove_devices() on failure during
the first loop iteration to fix this.

Commit 1e29af62f2 ("mfd: Add refcounting
support to mfd_cells") had to drop the "const" keyword on the "cell"
parameter of mfd_add_devices(), as it added the refcounting pointers
to the objects of the passed mfd_cell array itself.
However, the mfd core code operates on copies of the mfd_cell objects,
so there's no need to modify the originally passed objects.
Hence, move the setting of the refcounting pointers from mfd_add_devices()
to mfd_platform_add_cell(), where the copy of the mfd_cell objects is made.
mfd_clone_cell() can just pass (a copy of) the original usage_count
pointer.
This allows to make the "cell" parameter of mfd_add_devices() "const"
again, and avoids future race conditions when registering multiple
instances of the same device in parallel.

Instead of detecting the "tc3589x" and hard-coding the number of
GPIO pins to 24, encode all the possible subtypes and set the
number of GPIO pins from the type.

This registers ARIZONA_AOD_WKUP_AND_TRIG and ARIZONA_AOD_IRQ_RAW_STATUS
contain interrupt status bits and thus should be volatile. They are
correctly marked on wm5102 but not on wm5110, this patch changes this.
Furthermore volatile registers don't need defaults so remove those.

When setting GPIO defaults we are required to make a distinction
between writing 0x0000 to the registers and leaving them untouched.
When we receive between 0x0000 and 0xFFFF (inclusive) from either
Platform Data or Device Tree, we should write the provided
configuration to the device. Conversely, when we receive >0xFFFF we
should leave the device configuration at its default setting.
This patch fixes a bug and ensures that configuration 0x0000 isn't
mistakenly written when the intention was to keep the default one.

If platform data is passed when probing the device then it should take
precedence over Device Tree. This patch saves cycles in the pdata case
and prevents error messages when DT is not passed.

Palmas device supports multiple i2c device address and the client
for these addressed are created in the driver as i2c_new_dummy().
The new devices are not getting released in error or removal path and
so it is causing resource leak.
Add the unregister of these newly created dummy devices to avoid resource
leaks.
