Pawel Moll b99877f3f7 mfd: vexpress: Give the "leds-gpio" device a real parent
The registration of the "leds-gpio" device was using
"vexpress_sysreg_dev" as a parent before it was actually
set to something different than NULL.

Trivial fix by reordering the code.

Ulf Hansson caa62d6426 mfd: ab8500: sysctrl: Initialize driver at arch_initcall
The abx500-clk driver is initiated at arch_initcall level. Moreover it
is relying on the ab8500-sysctrl API to be available. Therefore move
ab8500-sysctrl to arch_initcall level as well. The device is already
added before the abx500 clk device, thus it will be probed before as
well, which is exactly what we want.

Lee Jones 741cdecfc5 mfd: db8500-prcmu: Return early if the TCPM cannot be located
Currently we check to see if we obtained the Tightly Coupled Program
Memory (TCPM) base and only execute the code within the check if we
have it. It's more traditional to return early if we don't have it.
This way we can flatten most of the function's code down to a single
tab spacing.

Mark Brown 6394678e6e mfd: wm8994: Don't use system PM operations
For realistic systems the power management is controlled entirely via
runtime PM - if the device is not runtime suspended then the suspend
will abort without doing anything as functionality such as accessory
detection or audio bypass will require the device to be enabled while
if the device is runtime suspended it is already in the lowest power
state. This means that system suspend is redundant and can be removed
which avoids issues with attempting to double disable the regulators.

Paul Bolle f2d614c4be mfd: da9055: Drop "select PMIC_DA9055"
The Kconfig entry for DA9055 PMIC Support selects PMIC_DA9055. That was
probably inspired by the similar select statement in the entry for
DA9052/53 PMIC with I2C. But the DA9055 PMIC only comes in an I2C
variant and its driver doesn't need a separate Kconfig symbol for shared
code. In any case, this select can be dropped as PMIC_DA9055 doesn't
exist.

Laxman Dewangan c4fbec3c6b mfd: palmas: Initialise client->of_node for dummy created client
Palmas device have three different i2c addresses. The device creates
the two new dummy i2c clients for accessing the register by using
primary client adapter. This new dummy i2c client have their of_node
as NULL.

The dummy i2c client is used for registering interrupt and on this,
it creates irq domain handle. This created irq domain handle has
their of_node as NULL.

Now when any child of this device is registered through the DT as
follows:
         palmas: tps65913@58 {
         	::::::::::::::::::

         	#interrupt-cells = <2>;
                interrupt-controller;

                palmas_rtc {
                       compatible = "ti,palmas-rtc";
                       interrupt-parent = <&palmas>;
                       interrupts = <8 0>;
                };
                ::::::::::;;;
         };

And child driver (palam-rtc in this case) get their irq number as
	irq = platform_get_irq(pdev, 0);

The returned irq number is error in this case. The reason is that
the created irq_domain handle for the palmas interrupt does not have
valid node and so matching of node fails with palmas node.

Hence initialising the newly dummy created client->of_node with the
primary clients of_node so that irq_domain handle have proper of_node
for matching.

For Nokia RX-51 there is rx51_battery power_supply driver which reporting
battery information via twl4030_madc_conversion. But this driver needs
raw values (not converted via some hardcoded functions). So this patch
adding new parameter "raw" to struct twl4030_madc_request which tell
twl4030-madc driver to not convert values, but rather return raw.

Mark Brown 247fa1920d mfd: arizona: Fully support the use of MCLK1 as the 32kHz clock source
MCLK1 is not in the AoD power domain so if it is used as the 32kHz clock
source we need to hold a runtime PM reference to keep the device from going
into low power mode.

Mark Brown 22c75fe7c7 mfd: arizona: Try to use interrupt flags from interrupt controller
If no irq_flags are passed in platform data then query the interrupt
controller for the trigger type and try to use that. This provides
default operation with a wider range of hardware and will be needed
for device tree support where the interrupt flags are configured on
the interrupt controller.
