On the Armada 370/XP/38x/39x SoCs when the suspend to ram feature is
supported, the SoCs are shutdown and will be woken up by an external
micro-controller, so there is no possibility to setup wake-up sources
from Linux. However, in standby mode, the SoCs stay powered and it is
possible to wake-up from any interrupt sources. Since when the users
configures the enabled wake-up sources there is no way to know if the
user will be doing suspend to RAM or standby, we just allow all
wake-up sources to be enabled, and only warn when entering suspend to
RAM
The purpose of this patch is to inform the user that in suspend to ram
mode, the wake-up sources won't be taken into consideration.

Clock rates are stored in an unsigned long field, but ->determine_rate()
(which returns a rounded rate from a requested one) returns a long
value (errors are reported using negative error codes), which can lead
to long overflow if the clock rate exceed 2Ghz.
Change ->determine_rate() prototype to return 0 or an error code, and pass
a pointer to a clk_rate_request structure containing the expected target
rate and the rate constraints imposed by clk users.
The clk_rate_request structure might be extended in the future to contain
other kind of constraints like the rounding policy, the maximum clock
inaccuracy or other things that are not yet supported by the CCF
(power consumption constraints ?).

This gets the GPIO ranges out of the driver and into the device
tree where they belong. Standard DT bindings already exist for
this. Since no systems with this are deployed we can just augment
all device trees and the drivers at the same time and simplify
the world.
This also defines the array of GPIO chips related to the pin
controller.

IRQCHIP_MASK_ON_SUSPEND by default, the platforms requiring them need
not override the irqchip flags as before.
This patch removes all the users of gic_set_irqchip_flags and the
function itself.

The UART0 is not used on these boards, yet active and blocking
other use. Fix this by disabling UART0 and setting port aliases
to maintain port enumeration to userspace.

Two fixes against v4.2-rc1. The first, for DRA7xx platforms,
corrects some incorrect GPMC hardware description data. The
second one will ensure that the hwmod code will wait for any
module with CPU-accessible registers to become ready before
attempting to access it.
Basic build, boot, and PM test logs are available here:
http://www.pwsan.com/omap/testlogs/omap-hwmod-a-for-v4.2-rc/20150723065408/
Note that I do not have a DRA7xx or AM43xx board, and therefore
cannot test on those platforms.

Until now only one Armada XP and one Armada 388 based board supported
suspend to ram. However, most of the recent mvebu SoCs can support the
standby mode. Unlike for the suspend to ram, nothing special has to be
done for these SoCs. This patch allows the system to use the standby
mode on Armada 370, 38x, 39x and XP SoCs. There are issues with the
Armada 375, and the support might be added (if possible) in a future
patch.

mvebu_pm_init and mvebu_armada_pm_init are only called during boot, so
flag them with __init and save some memory.

The pm-board.c code contains the board-specific logic to enter suspend
to RAM. Until now, the code supported only the Armada XP GP board, so
all functions and symbols were named with armada_xp_gp. However, it
turns out that the Armada 388 GP also uses the same 3 GPIOs protocol
to talk to the PIC microcontroller that controls the power supply.
Since we are going to re-use the same code with no change for Armada
38x, this commit renames the functions and symbols to use just
"armada" instead of "armada_xp_gp". Better names can be found if one
day other boards having a different protocol/mechanism are supported
in the kernel.
