The patch add basic support for the quad spi controller.
QSPI is a kind of spi module that allows single,
dual and quad read access to external spi devices. The module
has a memory mapped interface which provide direct interface
for accessing data form external spi devices.
The patch will configure controller clocks, device control
register and for defining low level transfer apis which
will be used by the spi framework to transfer data to
the slave spi device(flash in this case).
Test details:
-------------
Tested this on dra7 board.
Test1: Ran mtd_stesstest for 40000 iterations.
- All iterations went through without failure.
Test2: Use mtd utilities:
- flash_erase to erase the flash device
- mtd_debug read to read data back.
- mtd_debug write to write to the data flash.
diff between the write and read data shows zero.

Expand the arm64 image header to allow for co-existance with
PE/COFF header required by the EFI stub. The PE/COFF format
requires the "MZ" header to be at offset 0, and the offset
to the PE/COFF header to be at offset 0x3c. The image
header is expanded to allow 2 instructions at the beginning
to accommodate a benign intruction at offset 0 that includes

This patch adds ac97-slave support.
For ac97, the registers have to be setup earlier than for other ssi

ARM: tegra: core SoC enhancements for 3.12
This branch includes a number of enhancements to core SoC support for
Tegra devices. The major new features are:
* Adds a new CPU-power-gated cpuidle state for Tegra114.
* Adds initial system suspend support for Tegra114, initially supporting
just CPU-power-gating during suspend.
* Adds "LP1" suspend mode support for all of Tegra20/30/114. This mode
both gates CPU power, and places the DRAM into self-refresh mode.
* A new DT-driven PCIe driver to Tegra20/30. The driver is also moved
from arch/arm/mach-tegra/ to drivers/pci/host/.
The PCIe driver work depends on the following tag from Thomas Petazzoni:

Add irqchip driver for the ImgTec PowerDown Controller (PDC) as found in
the TZ1090. The PDC has a number of general system wakeup (SysWake)
interrupts (which would for example be connected to a power button or an
external peripheral), and a number of peripheral interrupts which can
also wake the system but are connected straight to specific low-power
peripherals (such as RTC or Infrared). It has a single interrupt output
for SysWakes, and individual interrupt outputs for each peripheral.
The driver demuxes the SysWake interrupt line, and passes the peripheral
interrupts straight through. It also handles the set_wake interrupt
operation to enable/disable the appropriate wake event bits.

Currently, rcutorture has separate torture_types to test synchronous,
asynchronous, and expedited grace-period primitives. This has
two disadvantages: (1) Three times the number of runs to cover the
combinations and (2) Little testing of concurrent combinations of the
three options. This commit therefore adds a pair of module parameters
that control normal and expedited state, with the default being both
types, randomly selected, by the fakewriter processes, thus reducing
source-code size and increasing test coverage. In addtion, the writer
task switches between asynchronous-normal and expedited grace-period
primitives driven by the same pair of module parameters.

Until today all gamepad input drivers report their data differently. It is
nearly impossible to write applications for more than one device in a
generic way. Therefore, this patch introduces a uniform gamepad API which
will be used for all new drivers.
Instead of mapping buttons by their labels, we now map them by position.
This allows applications to work with any gamepad regardless of the labels
on the buttons. Furthermore, we standardize the ABS_* codes for analog
triggers and sticks.
For D-Pads the long overdue BTN_DPAD_* codes are introduced. They should
be fairly obvious how to use. To avoid confusion, the action buttons now
have BTN_EAST/SOUTH/WEST/NORTH aliases.

Note that this commit also updates the formatting of serveral of the
bibtex entries to conform to that of my .bib files. I started
accumulating entries back in the 1980s, back when bibtex insisted
that comma (",") was a separator, not a terminator. This rule forced
commas to the fronts of lines. 25 years later, bibtex allows commas
to be terminators, but I am too lazy to rework all my .bib files.
Keeping the same format as my .bib files allows my to simply
incorporate my RCU.bib file into Documentation/RCU/RTFP.txt, which
is much easier than my earlier practice of keeping track of what
had changed and adding individual entries. (I sometimes find relevant
papers that were published some years back, for example.)
In addition, this change adds entries for papers published in the
last year or so.

Add core support to allow clock implementations to select the best
parent clock when rounding a rate, e.g. the one which can provide the
closest clock rate to that requested. This is by way of adding a new
clock op, determine_rate(), which is like round_rate() but has an extra
parameter to allow the clock implementation to optionally select a
different parent clock. The core then takes care of reparenting the
clock when setting the rate.
The parent change takes place with the help of some new private data
members. struct clk::new_parent specifies a clock's new parent (NULL
indicates no change), and struct clk::new_child specifies a clock's new
child (whose new_parent member points back to it). The purpose of these
are to allow correct walking of the future tree for notifications prior
to actually reparenting any clocks, specifically to skip child clocks
who are being reparented to another clock (they will be notified via the
new parent), and to include any new child clock. These pointers are set
by clk_calc_subtree(), and the new_child pointer gets cleared when a
child is actually reparented to avoid duplicate POST_RATE_CHANGE
notifications.
Each place where round_rate() is called, determine_rate() is checked
first and called in preference. This restructures a few of the call
sites to simplify the logic into if/else blocks.
