7a243b6323 mfd: twl-core: Make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config TWL4030_CORE
drivers/mfd/Kconfig:    bool "TI TWL4030/TWL5030/TWL6030/TPS659x0 Support"

...meaning that it currently is not being built as a module by anyone.

Lets remove what modular code that we can, so that when reading the
driver there is less doubt that it is builtin-only.  Note that we can't
remove the twl_remove() itself ; it is still used by the probe unwind
routine.  So we leave it linked into the .remove as well, even though
it will most likely never be called via that path from an unbind.

Since module_i2c_driver() uses the same init level priority as
builtin_i2c_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

We do that here, and confirm it can build and modpost as a tristate.
However there remains to be runtime testing in order to ensure this

b53046cbf8 mfd: ucb1x00: Remove NO_IRQ check
probe_irq_off() returns '0' on failure, not NO_IRQ, so the check
in this driver is clearly wrong. This replaces it with the
regular '!irq' check used in other drivers.

The sa1100 platform that this driver is used on originally numbered
all its interrupts starting at '0', which would have conflicted with
this change, but as of commit 18f3aec ("ARM: 8230/1: sa1100: shift
IRQs by one"), this is not a problem any more.

3612b27cfb mfd: arizona: Use suspend_noirq inplace of suspend_late
As runtime PM doesn't function whilst processing system suspend/resume
operations and the Arizona IRQ handlers need runtime PM to function
we must disable IRQs during these operations. Whilst this is
already done in the driver we are using suspend/suspend_late and
resume/resume_noirq to do so which has two problems. Firstly, as
suspend_late is before suspend_noirq that means we still have a
small window where an IRQ can cause issues.  Secondly, if another
suspend_late handler fails after ours has run then (as resume_noirq
will not run) we will make unbalanced calls to enable_irq.

This is all simply fixed by using the suspend_noirq callback rather
than suspend_late. Whilst we are doing this tidy the code up a little,
and use the appropriate helper macros.

75d8a2b041 mfd: arizona: Add sensible return value to some error paths
There are some cases in arizona_dev_init, such as where we don't
recognise the chip ID, in which we head to the error path without
setting a sensible error code in ret. This would lead to the chip
silently failing probe, as it would still return 0. Fix this up by
adding appropriate sets of the return value.

Whilst adding these update the existing paths that do return an error
when the chip is not recognised to use ENODEV, which seems like a better
fit.

The function da9052_clear_fault_log() is added to mitigate the case of
persistent data being transferred between reboots.

Clearance of any the persistent information within the DA9053 FAULT_LOG
register must be completed during start-up so the fault-log does not
continue with previous values. A clearance function has been added here in
the kernel driver because wiping the fault-log cannot be counted on outside

3526403353 mfd: qcom_rpm: Handle message RAM clock
The MSM8660, APQ8060, IPQ806x and MSM8960 have a GCC clock
to the message RAM used by the RPM. This needs to be enabled
for messages to pass through. This is a crude solution that
simply prepare/enable at probe() and disable/unprepare
at remove(). More elaborate PM is probably possible to
add later.

The construction uses IS_ERR() to gracefully handle the
platforms that do not provide a message RAM clock. It will
bail out of probe only if the clock is hitting a probe
deferral situation.

Of course this requires the proper device tree set-up:

rpm: rpm@104000 {
    compatible = "qcom,rpm-msm8660";
    clocks = <&gcc RPM_MSG_RAM_H_CLK>;
    clock-names = "ram";
    ...
};

I have provided this in the MSM8660 device tree, and will
provide patches for the other targets.

897ac6674c mfd: stmpe: Rework registers access
this update allows to use registers map as following :
regs[reg_index + offset] instead of
regs[reg_index] + offset

This makes code clearer and will facilitate the addition of STMPE1600
on which LSB and MSB registers are respectively located at addr and addr + 1.
Despite for all others STMPE variant, LSB and MSB registers are respectively
located in reverse order at addr + 1 and addr.

For variant which have 3 registers's bank, we use LSB,CSB and MSB indexes
which contains respectively LSB (or LOW), CSB (or MID) and MSB (or HIGH)
register addresses (STMPE1801/STMPE24xx).
For variant which have 2 registers's bank, we use LSB and CSB indexes only.
In this case the CSB index contains the MSB regs address (STMPE 1601).

82d8eb40ba mfd: max77620: Fix FPS switch statements
When configuring FPS during probe, assuming a DT node is present for
FPS, the code can run into a problem with the switch statements in
max77620_config_fps() and max77620_get_fps_period_reg_value(). Namely,
in the case of chip->chip_id == MAX77620, it will set
fps_[mix|max]_period but then fall through to the default switch case
and return -EINVAL. Returning this from max77620_config_fps() will
cause probe to fail.

f37be01e6d mfd: qcom_rpm: Parametrize also ack selector size
The RPM has two sets of selectors (IPC bit fields): request and
acknowledge. Apparently, some models use 4*32 bit words for select
and some use 7*32 bit words for request, but all use 7*32 words
for acknowledge bits.

So apparently you can on the models with requests of 4*32 select
bits send 4*32 messages and get 7*32 different replies, so on ACK
interrupt, 7*32 bit words need to be read. This is how the vendor
code apparently works.
