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.

ARM: ux500: move PM-related PRCMU functions to machine
We are trying to decompose and decentralize the code in
the DB8500 PRCMU out into subdrivers. The code moved in
this patch concerns a group of functions used for
decoupling and recoupling the IRQs from the GIC. During
sleep and idle the Ux500 system will transfer all IRQ
handling to the PRCMU using these functions.
Basically we are left with the two alternatives of code
placement as:
- arch/arm/mach-ux500/pm.c - this because the code is
closely related to the GIC, and takes ownership of
some of the registers from the PRCMU related to this
PM functionality.
- drivers/mfd/db8500-prcmu-pm.c - because the code is
affecting stuff in the PRCMU register range. But then
this code needs to remap and handle GIC registers.
This patch implementation is taking the first approach.
Currently the cpuidle driver is the only piece of code
using this set of functions, but it will later also be
used by the suspend/resume code which is currently under
review.
The header file is moved to:
<linux/platform_data/arm-ux500-pm.h>
The function prototypes need to be placed in a globally
visible header since the CPUidle code is planned to move
out to drivers/cpuidle.

mfd: abx500: Move the AB8500 Kconfig fragment
Move the AB8500 Kconfig fragment below the AB3100 so the
menuconfig menu gets hierarchically nested and looks nice.
Having the EZX PCAP in the middle disturbs the nice
hierarchical layout from kconfig.
