Kevin Hilman f7ec0b0b16 omap: GPIO: fix auto-disable of debounce clock
The addition of the new debounce code (commit
168ef3d9a5) broke the auto-disable of
debounce clocks on idle by forgetting to update the debounce clock
enable mask.

Add back the updating of bank->dbck_enable_mask so debounce clocks are
auto-disabled.

Tero Kristo 856f191451 omap: DMTIMER: Ack pending interrupt always when stopping a timer
The kernel timer queue is being run currently from a GP timer running in a one
shot mode, which works in a way that when it expires, it will also stop.
Usually during this situation, the interrupt handler will ack the interrupt,
load a new value to the timer and start it again. During suspend, the
situation is slightly different, as we disable interrupts just before
timekeeping is suspended, which leaves a small window where the timer can
expire before it is stopped, and will leave the interrupt flag pending.
This pending interrupt will prevent ARM sleep entry, thus now we ack it always
when we are attempting to stop a timer.

Paul Walmsley d74b494971 OMAP2+ clock: remove DEFAULT_RATE clksel_rate flag
The DEFAULT_RATE clksel_rate flag is essentially useless.  It was set
on some of the lowest divisors, which, when switching to a much
higher-rate parent, could have potentially resulted in rates that
exceeded the hardware specifications for downstream clocks in the
window between the clk_set_parent(), and a subsequent clk_set_rate().
It seems much safer to just remove the flag and always use the highest
available divisor (resulting in the lowest possible rate) after the
switch, and this patch does so.

Ideally, it would be best to first attempt to switch to a divisor that
matches the clock's rate with the previous parent, if at all possible.
But that is a project for some other day or some other person.  The
parent changing code is rarely used.

Kalle Jokiniemi 20c9d2c4ab i2c-omap: add mpu wake up latency constraint in i2c
While waiting for completion of the i2c transfer, the
MPU could hit OFF mode and cause several msecs of
delay that made i2c transfers fail more often. The
extra delays and subsequent re-trys cause i2c clocks
to be active more often. This has also an negative
effect on power consumption.

Created a mechanism for passing and using the
constraint setting function in driver code. The used
mpu wake up latency constraints are now set individually
per bus, and they are calculated based on clock rate
and fifo size.

Thanks to Jarkko Nikula, Moiz Sonasath, Paul Walmsley,
and Nishanth Menon for tuning out the details of
this patch.

Updates by Kevin as requested by Tony:

- Remove omap_set_i2c_constraint_func() in favor of conditionally
  adding the flag in omap_i2c_add_bus() in order to keep all the OMAP
  conditional checking in a single location.
- Update set_mpu_wkup_lat prototypes to match OMAP PM layer so
  OMAP PM function can be used directly in pdata.

Hiroshi DOYU e0a42e4fcb omap iommu: Exit iteration if no possibility of available area
Searching avaialable spaces should be stopped as soon as it turns out
that there's no possibility with the rest of it.

Hiroshi DOYU fa460b88e0 omap iommu: Insert a gap page between IOVMAs against override
Inserting a gap page between IOVMAs could detect an override on other
IOVMA with iommu fault. This was originally suggested by Sakari Ailus
and based on the work and comment by David Cohen.

Hiroshi DOYU 37c2836c45 omap iommu: Introduce iteration macro for iotlb entry scan
There are some places to scan iotlb entries. This iteration macro
could make these code a bit simpler with proceeding iotlb entries
transparently.

Kevin Hilman d009559a42 OMAP: GPIO: remove duplicate debugfs interface
The generic gpiolib provides a debugfs interface to GPIOs which
provides identical (but nicer looking) data as the OMAP specific one.

This patch completely drops the OMAP specific interface
(/debug/omap_gpio) in favor of using the generic one (/debug/gpio.)

Ensure GPIO debounce clocks are disabled when idle.  Otherwise,
clocks will prevent PER powerdomain from entering retention.

Kevin Hilman 43ffcd9a04 OMAP2/3: GPIO: generalize prepare for idle
Currently, the GPIO 'prepare' hook is only called when going to
off-mode, while the function is called 'prepare_for_retention.'  This
patch renames the function to 'prepare_for_idle' and calls it for any
powersate != PWRDM_POWER_ON passing in the powerstate.

The hook itself is then responsible for doing various preparation
based on the powerstate.
