Per Forlin d49278e335 dmaengine: dma40: Add support to split up large elements
The maximum transfer size of the stedma40 is (64k-1) x data-width.
If the transfer size of one element exceeds this limit
the job is split up and sent as linked transfer.

Russell King 5e06b6492e ARM: ensure all sched_clock() implementations are notrace marked
ftrace requires sched_clock() to be notrace.  Ensure that all
implementations are so marked.  Also make sure that they include
linux/sched.h

Also ensure OMAP clocksource read functions are marked notrace as
they're used for sched_clock() too.

Rabin Vincent dacdc96cd3 nomadik-gpio: allow sleep mode dir/pull to differ from normal mode
In the nomadik GPIO pin configuration, allow the sleep mode direction
and pull configurations to differ from the ones for the normal state.
PIN_SLPM_PULL_*, PIN_SLPM_INPUT, PIN_SLPM_OUTPUT* macros are provided
for this.

Since the hardware does not allow seperate configurations for sleep mode
and normal mode, this is implemented by having software remux the
configurations as necessary.

Linus Walleij 8fbb97a2bc ARM: 6488/1: nomadik: prevent sched_clock() wraparound
The current implementation of sched_clock() for the Nomadik
family is based on the clock source that will wrap around without
any compensation. Currently on the Ux500 after 1030 seconds.

Utilize cnt32_to_63 to expand the sched_clock() counter to 63
bits and introduce a keepwarm() timer to assure that sched clock
and this cnt32_to_63 is called atleast once every half period.

When I print out the actual wrap-around time, and using
a year (3600*24*365 seconds) as minumum wrap limit I get an
actual wrap-around of:
sched_clock: using 55 bits @ 8333125 Hz wrap in 416 days

This fixes a section mismatch reported by modpost:

	WARNING: arch/arm/plat-nomadik/built-in.o(.data+0x100): Section mismatch in reference from the variable nmk_gpio_driver to the function .init.text:nmk_gpio_probe()
	The variable nmk_gpio_driver references
	the function __init nmk_gpio_probe()
	If the reference is valid then annotate the
	variable with __init* or __refdata (see linux/init.h) or name the variable:
	*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,

According to Rabin VINCENT the alternative to use platform_driver_probe
won't work because the "platform devices are not yet registered when

Rabin Vincent 6647c6c0b6 ARM: 6147/1: nomadik-gpio: set val in ->direction_output()
The ->direction_output() callback needs to set the value it was passed,
in addition to setting the direction as output.  On this peripheral, we
can't set the value before setting the direction, so set it after.

Linus Walleij ba327b1e52 ARM: 6145/1: ux500 MTU clockrate correction
This adjusts the clockrate for the MTU timer. On the different
UX500 variants this rate is different. The platform can also have
been set up at hardware initialization, bootloader or early init
for different clock speeds. To have the clock framework available
early so the timers can use them, the clock initialization for
Nomadik and ux500 is moved to IRQ init time. A custom per-clock
callback is added to handle special cases like this.

This solves a user-visible bug: without this patch the current
UX500 platforms will not be synchronized to wall-clock time and
the platform will drift in time.

Linus Walleij 2a847513cd ARM: 6107/1: plat-nomadik: use the MTU clocksrc for sched_clock
This provides some serious scheduling for the Nomadik family by
introducing a sched_clock() using the MTU clock source in the
same manner as e.g. OMAP or U300. This type of solutions has been
discussed at no end in the past, however we need this resolution
for making measurements and using HRTimers.
