This patch fixes a possible timeout in poll loop without actually
checking the register before return. In theory the there is a possibility
of loop being scheduled after a long lock/delay, which would then force
the loop to exit without actually checking the register.

In case of multi-phy PHY providers, each PHY should be modeled as a sub

The Berlin SoC has a two SATA ports. Add a PHY driver to handle them.
The mode selection can let us think this PHY can be configured to fit
other purposes. But there are reasons to think the SATA mode will be
the only one usable: the PHY registers are only accessible indirectly
through two registers in the SATA range, the PHY seems to be integrated
and no information tells us the contrary. For these reasons, make the
driver a SATA PHY driver.

DMA interrupts are now available in of, and the definitions are

Signed-off-by: Tony Lindgren <tony@atomide.com>
we have currently 2 DMA drivers that try to co-exist.
drivers/dma/omap-dma.c which registers it's own IRQ and is device tree
aware and uses arch/arm/plat-omap/dma.c instance created by
arch/arm/mach-omap2/dma.c to maintain channel usage (omap_request_dma).
Currently both try to register interrupts and mach-omap2/plat-omap dma.c
attempts to use the IRQ number registered by hwmod to register it's own
interrupt handler.
Now, there is no reasonable way of static allocating DMA irq in GIC
SPI when we use crossbar. However, since the dma_chan structure is
freed as a result of IRQ not being present due to devm allocation,
maintaining information of channel by platform code fails at a later
point in time when that region of memory is reused.
So, if hwmod does not indicate an IRQ number, then, assume that
dma-engine will take care of the interrupt handling.

Commit 75b57ecf9 refactored device tree nodes to use kobjects such that they
can be exposed via /sysfs. A secondary commit 0829f6d1f furthered this rework
by moving the kobect initialization logic out of of_node_add into its own
of_node_init function. The inital commit removed the existing kref_init calls
in the pseries dlpar code with the assumption kobject initialization would
occur in of_node_add. The second commit had the side effect of triggering a
BUG_ON during DLPAR, migration and suspend/resume operations as a result of
dynamically added nodes being uninitialized.
This patch fixes this by adding of_node_init calls in place of the previously
removed kref_init calls.

The above warnins happen because those functions are used only
when the V4L2 subdev API is enabled.

====================
sparc64 io refactoring
The following patchset refactor io_64.h. This was triggered by
another patchset by Thierry Reding that updates the the generic
io.h such that it may be used by sparc64 and thus make sparc
and sparc64 more equal in this area.
Before attempting to introduce the generic version it was
necessary to clean up the current state to avoid any mistakes.
The updates from Thierry needs to go in before I will attempt
introducing the generic io.h.
The sparcspkr used inb()/outb() primitives
for of_ioremap() memory. Update this driver to use sbus_ variants.
This change was triggered by a number of new warnings that would otherwise
have been seen when dropping the macro indirections.
Likewise PeeCeeI.c had some warnings that was fixed by
using another IO varaint - which simplified the code too.
The patchs has been generated with the --histogram option
to make the patch that re-order functions in io_64.h
more readable.
So to see the same patches locally you need this option too.
I have not yet any working sparc64 HW - so this is not tested.
But I brought a SUN NetraX1 that I am working on gettting
running. That may allow me to do some minimal tests in the future.

Several of the small IO functions ended up having the same implementation.
Use __raw_{read,write}* + {read,write}* as base for the others.
Continue to use static inline functions to get full type check.
The size of vmlinux for a defconfig build was the same when
using static inline and macros for the functions - so there
was no size win when using macros.
This was tested with gcc 4.8.2 + binutils 2.24.
For such simple constructs I assume older gcc's will
do the same job.

Reorder functions so __raw_{read,write}* functions comes first,
followed by {read,write}*
Update comments for the two blocks of functions.

They are no longer used.
All hits in the kernel are essential unused code or comments
