Roel Kluin f1acb878b6 iop-adma: redundant/wrong tests in iop_*_count()?
When we reach the loop, len is at least 1, we only stay in the loop when
len is at least MAX_BYTE_COUNT + 1, MAX_BYTE_COUNT is subtracted in each
iteration. So when we leave the loop, or didn't take it, len is at least 1.
Testing whether len is non-zero appears redundant.

Erik Benada cf11052a95 [ARM] orion5x: D-link DNS-323 rev. B1 power-off
This patch fixes power LED blinking and power-off on DNS-323 rev. B1.

GPIO pin 3 has to be set to 1 to stop power LED blinking and to allow the LED to be controlled via leds-gpio. This pin has to be also set to 1 for power-off to work.
To power-off the rev. B1 machine, pin 8 has to be set to 1 and then set to 0 to do actual power-off.

Tested on my DNS-323 rev. B1

Tero Kristo 5c3db36bf6 OMAP2/3: DMTIMER: Clear pending interrupts when stopping a timer
OMAP GP timers keep running for a few cycles after they are stopped,
which can cause the timer to expire and generate an interrupt. The
pending interrupt will prevent e.g. OMAP from entering suspend, thus
we ack it manually.  Only applicable on OMAP2/3/4.

Kevin Hilman d92cfcbe39 OMAP: timekeeping: time should not stop during suspend
During suspend, the kernel timekeeping subsystem is shut down.  Before
suspend and upon resume, it uses a weak function
read_persistent_clock() to determine the amount of time that elapsed
during suspend.

This function was not implemented on OMAP, so from the timekeeping
subsystem perspective (and thus userspace as well) it appeared that no
time elapsed during suspend.

This patch uses the 32k sync timer as a the persistent clock.

NOTE: This does *NOT* fully handle wrapping of the 32k sync timer, so
      more than one wrapping of the 32k sync timer during suspend may
      cause problems.  Also note there are not interrupts when the 32k
      sync timer wraps, so something else has to be done.

Thara Gopinath 883edfdd58 OMAP3: hwmod: Adding flag to prevent caching of sysconfig register.
In the current implementation the sysconfig value is read into
 _sysc_cache once and an actual update to the sysconfig register
happens only if the new value paased is differnt from the one in _sysc_cache.
_sysc_cache is updated only if _HWMOD_SYSCONFIG_LOADED is not set.
This can lead to the follwing issue if off mode is enabled in modules
which employs "always-retore" mechanism of context save and restore.

        a. The module sets the sysconfig register through omap_device_enable.
           Here _sysc_cache is updated with the value written to the sysconfig
           register and left.
        b. The power domain containig the module enters off mode and the
           module context is lost.
        c. The module in use becomes active and calls omap_device_enable to
           enable itself. Here a read of sysconfig register does not happen
           as _HWMOD_SYSCONFIG_LOADED flag is set. The value to be written
           to the sysconfig register will be same as the one written in step a.
           Since _sysc_cache reflects the previous written value an update
           of the sysconfig register does not happen.
This means in modules which employs "always-restore" mechanism
after off , the sysconfig regsiters will never get updated.

This patch introduces a flag SYSC_NO_CACHE which if set ensures that the
sysconfig register is always read into _sysc_cache before an update is
attempted.

This flags need to be set only by modules which does not do a context save
but re-initializes the registers every time the module is accessed. This
includes modules like i2c, smartreflex etc.

Ben Dooks 3ce2f76f5d ARM: MINI2440: Fixup __initdata usage
Remove some of the __initdata tags which are currently inappropriate for
platform_device and some of the platform data. These can be returned once
support for copying platform devices and data is added.

Mark Brown d3cf4489d5 ARM: SMDK6410: Specify no GPIO for B_PWR_5V regulator
Since the fixed voltage regulator grew support for GPIO based
enables and GPIO 0 is valid on some systems we need to specify
that there is no valid GPIO enable control.

Ramax Lo 9b96918a97 ARM: S3C: NAND: Check the existence of nr_map before copying
Since the structure field nr_map is optional, we need to check whether the
chip number map is provided to avoid unexpected NULL pointer exception.
