6dd6bca3fb mmc: sd: clean up redundant memset
The clearing of mrq via a memset at the top of the for loop in
mmc_wait_for_app_cmd() is not required as mrq is not used and there is
another clearing of mrq just below.  We remove the first memset since if
the initial tests in the for loop fail the memset is not required.

bbce5802af davinci: mmc: updates to suspend/resume implementation
Improve the suspend and resume callbacks in DaVinci MMC host controller
driver.  Modify the reset status of the contorller and clock during
suspend and resume.  Also migrate the power management callbacks from
platform driver to dev_pm_ops structure.

Tested on DA850/OMAP-L138 EVM.

f27f47ef5b sdhci: implement CAP_CLOCK_BASE_BROKEN quirk
Some hosts (e.g.  as found in CNS3xxx SOCs) report wrong value in
CLOCK_BASE capability field, and currently there is no way to force the
SDHCI core to use the platform-provided base clock value.

This patch implements CAP_CLOCK_BASE_BROKEN quirk.  When enabled, the
SDHCI core will always use base clock frequency provided by the platform.

0e950fa686 mmc-omap: add support for 16-bit and 32-bit registers
The omap850 and omap730 use 16-bit registers instead of 32-bit, requiring
a modification of the register addresses in the mmc-omap driver.  To
resolve this, a bit shift is performed on base register addresses, either
by 1 or 2 bits depending on the CPU in use.  This yields the correct
registers for each CPU.

ca2afb6dbe davinci: mmc: pass number of SG segments as platform data
On some platforms like DM355, the number of EDMA parameter slots available
for EDMA_SLOT_ANY usage are few.  In such cases, if MMC/SD uses 16 slots
for each instance of MMC controller, then the number of slots available
for other modules will be very few.

By passing the number of EDMA slots to be used in MMC driver from platform
data, EDMA slots available for other purposes can be controlled.

Most of the platforms will not use this platform data variable.  But on
DM355, as the number of EDMA resources available is limited, the number of
scatter- gather segments used inside the MMC driver can be 8 (passed as
platform data) instead of 16.  On DM355, when the number of scatter-gather
segments was reduced to 8, I saw a performance difference of about
0.25-0.4 Mbytes/sec during write.  Read performance variations were
negligible.

067fb2f648 Input: ads7846 - return error on regulator_get() failure
In probe(), if regulator_get() failed, an error code was not being
returned causing the driver to be successfully bound, even though
probe failed.  This in turn caused the suspend, resume and remove
methods to be registered and accessed via the SPI core.  Since these
functions all access private driver data using pointers that had been
freed during the failed probe, this would lead to unpredictable
behavior.

This patch ensures that probe() returns an error code in this failure
case so the driver is not bound.

Found using lockdep and noticing the lock used in the suspend/resum
path pointed to a bogus lock due to the freed memory.

ee378a5c65 backlight: add S6E63M0 AMOLED LCD Panel driver
This is S6E63M0 AMOLED LCD Panel(480x800) driver using 3-wired SPI
interface also almost features for lcd panel driver has been implemented
in here.  and I added new structure common for all the lcd panel drivers
to include/linux/lcd.h file.

LCD Panel driver needs interfaces for controlling device power such as
power on/off and reset.  these interfaces are device specific so it should
be implemented to machine code at this time, we should create new
structure for registering these functions as callbacks and also a header
file for that structure and finally registered callback functions would be
called by lcd panel driver.  such header file(including new structure for
lcd panel) would be added for all the lcd panel drivers.

If anyone provides common structure for registering such callback
functions then we could reduce unnecessary header files for lcd panel.  I
thought that suitable anyone could be include/linux/lcd.h so a new
lcd_platform_data structure was added there.

1e653accf7 leds: leds-ss4200: fix led_classdev_unregister twice in error handling
In current implementation, if device_create_file failed in register_nasgpio_led,
led_classdev_unregister will be executed twice.
( in register_nasgpio_led it calls led_classdev_unregister before return and in nas_gpio_init out_err )

This patch fixes it by only unregistering those that were successfully registered in out_err.
( not including last failed register_nasgpio_led call )

2146325df2 leds: leds-gpio: Change blink_set callback to be able to turn off blinking
The leds-gpio blink_set() callback follows the same prototype as the
main leds subsystem blink_set() one.

The problem is that to stop blink, normally, a leds driver does it
in the brightness_set() callback when asked to set a new fixed value.

However, with leds-gpio, the platform has no hook to do so, as this
later callback results in a standard GPIO manipulation.

This changes the leds-gpio specific callback to take a new argument
that indicates whether the LED should be blinking or not and in what
state it should be set if not. We also update the dns323 platform
which seems to be the only user of this so far.

578454ff7e driver core: add devname module aliases to allow module on-demand auto-loading
This adds:
  alias: devname:<name>
to some common kernel modules, which will allow the on-demand loading
of the kernel module when the device node is accessed.

Ideally all these modules would be compiled-in, but distros seems too
much in love with their modularization that we need to cover the common
cases with this new facility. It will allow us to remove a bunch of pretty
useless init scripts and modprobes from init scripts.

The static device node aliases will be carried in the module itself. The
program depmod will extract this information to a file in the module directory:
  $ cat /lib/modules/2.6.34-00650-g537b60d-dirty/modules.devname
  # Device nodes to trigger on-demand module loading.
  microcode cpu/microcode c10:184
  fuse fuse c10:229
  ppp_generic ppp c108:0
  tun net/tun c10:200
  dm_mod mapper/control c10:235

Udev will pick up the depmod created file on startup and create all the
static device nodes which the kernel modules specify, so that these modules
get automatically loaded when the device node is accessed:
  $ /sbin/udevd --debug
  ...
  static_dev_create_from_modules: mknod '/dev/cpu/microcode' c10:184
  static_dev_create_from_modules: mknod '/dev/fuse' c10:229
  static_dev_create_from_modules: mknod '/dev/ppp' c108:0
  static_dev_create_from_modules: mknod '/dev/net/tun' c10:200
  static_dev_create_from_modules: mknod '/dev/mapper/control' c10:235
  udev_rules_apply_static_dev_perms: chmod '/dev/net/tun' 0666
  udev_rules_apply_static_dev_perms: chmod '/dev/fuse' 0666

A few device nodes are switched to statically allocated numbers, to allow
the static nodes to work. This might also useful for systems which still run
a plain static /dev, which is completely unsafe to use with any dynamic minor
numbers.

Note:
The devname aliases must be limited to the *common* and *single*instance*
device nodes, like the misc devices, and never be used for conceptually limited
systems like the loop devices, which should rather get fixed properly and get a
control node for losetup to talk to, instead of creating a random number of
device nodes in advance, regardless if they are ever used.

This facility is to hide the mess distros are creating with too modualized
kernels, and just to hide that these modules are not compiled-in, and not to
paper-over broken concepts. Thanks! :)

it can get beacon transmissions stuck during synchronization.
Use SWBA based beacon trasmission similar to AP mode instead.

49bbd815fd fb_defio: fix for non-dirty ptes
Fix a problem observed while using fb_defio with a short delay on a
PowerPC platform.

It is possible that page_mkclean() is invoked in the deferred io work
function _before_ a PTE has been marked dirty.  In this case, the page is
removed from the defio pagelist but page_mkclean() does not write-protect
the page again.  The end result is that defio ignores all subsequent
writes to the page and the corresponding portions of the framebuffer never
get updated.

The fix consists in keeping track of the pages with non-dirty PTEs,
re-checking them again on the next deferred io work iteration.  Note that
those pages are not passed to the defio callback as they are not written
by userspace yet.

1f9c3e1f07 fbdev: da8xx/omap-l1xx: implement double buffering
This work includes the following:

- Implement handler for FBIO_WAITFORVSYNC ioctl.

- Allocate the data and palette buffers separately.  A consequence of
  this is that the palette and data loading is now done in different
  phases.  And that the LCD must be disabled temporarily after the palette
  is loaded but this will only happen once after init and each time the
  palette is changed.  I think this is OK.

- Allocate two (ping and pong) framebuffers from memory.

- Add pan_display handler which toggles the LCDC DMA registers between
  the ping and pong buffers.

6ba8bcd457 rtc-cmos: do dev_set_drvdata() earlier in the initialization
The bug is an oops when dev_get_drvdata() returned null in
cmos_update_irq_enable().  The call tree looks like this:
  rtc_dev_ioctl()
    => rtc_update_irq_enable()
      => cmos_update_irq_enable()

It's caused by a race condition in the module initialization.  It is
rtc_device_register() which makes the ioctl operations live so I moved
the call to dev_set_drvdata() before the call to rtc_device_register().

72cc8e51cf rtc-ds1302: add some abstraction for new platform support
The current ds1302 driver (or at least the one that lives in /drivers/rtc)
seems to be designed for memory mapped devices only.  This make it quite
hard to add support for GPIO-based implementations (as this is the case
for the upcoming Arcom Vulcan).

This patch moves the direct register access to inline functions with
explicit names.  Still not as good as a proper platform driver, but at
least neater.

6d94d40810 lis3: interrupt handlers for 8bit wakeup and click events
Content for the 8bit device threaded interrupt handlers.  Depending on the
interrupt line and chip configuration, either click or wakeup / freefall
handler is called.  In case of click, BTN_ event is sent via input device.
 In case of wakeup or freefall, input device ABS_ events are updated
immediatelly.

It is still possible to configure interrupt line 1 for fast freefall
detection and use the second line either for click or threshold based
interrupts.  Or both lines can be used for click / threshold interrupts.

Polled input device can be set to stopped state and still get coordinate
updates via input device using interrupt based method.  Polled mode and
interrupt mode can also be used parallel.

BTN_ events are remapped based on existing axis remapping information.

342c5f1281 lis3: introduce platform data for second ff / wu unit
8 bit device has two wakeup / free fall units.  It was not possible to
configure the second unit.  This patch introduces configuration entry to
the platform data and also corresponding changes to the 8 bit setup
function.

High pass filters were enabled by default.  Patch introduces configuration
option for high pass filter cut off frequency and also possibility to
disable or enable the filter via platform data.  Since the control is a
new one and default state was filter enabled, new option is used to
disable the filter.  This way old platform data is still compatible with
the change.

940370fc86 hangcheck-timer: fix x86_32 bugs
drivers/char/hangcheck-timer.c is doubly broken.  When the overflown value
of TIMER_FREQ is abnormally low, it spams the syslog with KERN_CRIT
messages "Hangcheck: hangcheck value past margin!" But whether it happens
or not depends on HZ and lpj in a complex way.  People have hit it
occasionally as far as google search can tell.

First, the following line overflows unsigned long:

# define TIMER_FREQ (HZ*loops_per_jiffy)

Second, and more importantly, loops_per_jiffy has little to do with the
con= version from the the time scale of get_cycles() (aka rdtsc) to the
time scale of jiffies.

The attached patch resolves both of the problems.

1f85f87d4f cpuidle: add a repeating pattern detector to the menu governor
Currently, the menu governor uses the (corrected) next timer as key item
for predicting the idle duration.

It turns out that there are specific cases where this breaks down: There
are cases where we have a very repetitive pattern of idle durations, where
the idle period is pretty much the same, for reasons completely unrelated
to the next timer event.  Examples of such repeating patterns are network
loads with irq mitigation, the mouse moving but in theory also the wifi
beacons.

This patch adds a relatively simple detector for such repeating patterns,
where the standard deviation of the last 8 idle periods is compared to a
threshold.

With this extra predictor in place, measurements show that the DECAY
factor can now be increased (the decaying average will now decay slower)
to get an even more stable result.

True. In such a case, even a valid request would be lost! So now

 - check if get_mode is present to avoid oops;
 - if get_mode is not present, proceed anyways for the request.

3e3d3be79c twl6030: regulator: Remove vsel tables and use formula for calculation
All twl6030 regulators can be programmed from 1.0v to 3.3v
with 100mV steps.
The below formula can be used to calculate the vsel values
to be programmed in the VREG_VOLTAGE registers.

Voltage(in mV) = 1000mv + 100mv * (vsel - 1)

Ex: if vsel = 0x9, mV = 1000 + 100 * (9 -1) = 1800mV.

This patch removes all existing VSEL tables for twl6030 adjustable
regulators and just uses the formula directly for vsel calculations
after verifing they fall in the allowed range.

statements are used to check the boundary of voltage numbers since voltage
number isn't linear.

Now use array of voltage numbers instead. Clean code with simpler way.

23b5cc2ab6 regulator: prevent registration of matching regulator consumer supplies
Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

Pointer comparison is not sufficient for non-NULL device name matching,
so use strcmp(). Otherwise the semantics remain the same.

0178f3e28e regulator: Allow regulator-regulator supplies to be specified by name
When one regulator supplies another allow the relationship to be specified
using names rather than struct regulators, in a similar manner to that
allowed for consumer supplies. This allows static configuration at compile
time, reducing the need for dynamic init code.

Also change the references to LINE supply to be system supply since line
is sometimes used for actual supplies and therefore potentially confusing.

7e6811daa6 iTCO_wdt: fix TCO V1 timeout values and limits
For TCO V1 devices the programmed timeout was twice too long
because the fact that the TCO V1 timer needs to count down
twice before triggering the watchdog, wasn't accounted for.
Also the timeout values in the module description and error
message were clarified. And the _STS registers are 16 bit
instead of 8 bit.
