On some DDR controllers, compatible with the sama5d3 one,
the sequence to enter/exit/re-enter the self-refresh mode adds
more constrains than what is currently written in the at91_idle
driver. An actual access to the DDR chip is needed between exit
and re-enter of this mode which is somehow difficult to implement.
This sequence can completely hang the SoC. It is particularly
experienced on parts which embed a L2 cache if the code run
between IDLE calls fits in it...
Moreover, as the intention is to enter and exit pretty rapidly
from IDLE, the power-down mode is a good candidate.
So now we use power-down instead of self-refresh. As we can
simplify the code for sama5d3 compatible DDR controllers,
we instantiate a new sama5d3_ddr_standby() function.

now be selected directly.
- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
is now selectable by everyone, so we need not declare our
intent to select it.
When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

Many ARM sub-architectures use prompts followed by "if" conditional,
but it is wrong.
Please notice the difference between
config ARCH_FOO
bool "Foo SoCs" if ARCH_MULTI_V7
and
config ARCH_FOO
bool "Foo SoCs"
depends on ARCH_MULTI_V7
These two are *not* equivalent!
In the former statement, it is not ARCH_FOO, but its prompt that
depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO
is selected by another, but ARCH_MULTI_V7 is still disabled. As it is
not unmet dependency, Kconfig never warns. This is probably not what
you want.
The former should be used only when you need to do so, and you really
understand what you are doing. (In most cases, it should be wrong!)
For enabling/disabling sub-architectures, the latter is always correct.
As a good side effect, this commit fixes some entries over 80 columns
(mach-imx, mach-integrator, mach-mbevu).

the discussion that followed, but I can see value in being consistent

Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
This change modifies gen_pool_get() and devm_gen_pool_create() client
interfaces adding one more argument "name" of a gen_pool object.
Due to implementation gen_pool_get() is capable to retrieve only one
gen_pool associated with a device even if multiple gen_pools are created,
fortunately right at the moment it is sufficient for the clients, hence
provide NULL as a valid argument on both producer devm_gen_pool_create()
and consumer gen_pool_get() sides.
Because only one created gen_pool per device is addressable, explicitly
add a restriction to devm_gen_pool_create() to create only one gen_pool
per device, this implies two possible error codes returned by the
function, account it on client side (only misc/sram). This completes
client side changes related to genalloc updates.

are also here (acked by appropriate maintainers):
- power key input driver for Freescale platforms (svns)
- RTC driver updates for Freescale platforms (svns/mxc)
- clk fixes for TI DM814/816X

A large cleanup branch this release, with a healthy 10k negative line delta.
Most of this is removal of legacy (non-DT) support of shmobile
platforms. There is also removal of two non-DT platforms on OMAP,
and the plat-samsung directory is cleaned out by moving most of the
previously shared-location-but-not-actually-shared files from there to
the appropriate mach directories instead.
There are other sets of changes in here as well:
- Rob Herring removed use of set_irq_flags under all platforms and
moved to genirq alternatives
- A series of timer API conversions to set-state interface
- ep93xx, nomadik and ux500 cleanups from Linus Walleij
- __init annotation fixes from Nicolas Pitre
+ a bunch of other changes that all add up to a nice set of cleanups

To be consistent with other genalloc interface namings, rename
dev_get_gen_pool() to gen_pool_get(). The original omitted "dev_" prefix
is removed, since it points to argument type of the function, and so it
does not bring any useful information.

Drop AT91_TIMER_HZ as this can be handled using HZ_FIXED. Initial help message
was:
On AT91rm9200 chips where you're using a system clock derived
from the 32768 Hz hardware clock, this tick rate should divide
it exactly: use a power-of-two value, such as 128 or 256, to
