Proper ndelay implementation allows for faster IO rate with drivers that
use ndelay to access their device registers, as otherwise ndelay is
emulated with udelay.

Replace division with shift, use ccount_freq instead of loops_per_jiffy.
Introduce __MAX_UDELAY and (undefined) __bad_udelay, break build for too
big udelay constants.
Remove irrelevant comment, clean up code style.

Use the simple-bus node to discover the io area, and remap the cached and
bypass io ranges. The parent-bus-address value of the first triplet in the
"ranges" property is used. This value is rounded down to the nearest 256MB
boundary. The length of the io area is fixed at 256MB; the "ranges" property
length value is ignored.
Other limitations: (1) only the first simple-bus node is considered, and (2)
only the first triplet of the "ranges" property is considered.
See ePAPR 1.1 §6.5 for the simple-bus node description, and §2.3.8 for the
"ranges" property description.

The recommended compatible string format, according to the ePAPR v1.1 standard,
is "manufacturer,model". Change the xtensa cpu compatible strings to
"cdns,xtensa-cpu". Also, change the boards compatible strings in a similar way.

there is a small possibility that wake_up of softirq thread
happens between local_irq_enable() and set_cpu_online(). In
this case affinity of the thread changes to fallback affinity
(i.e. CPU0). This may be a source of problems.
The patch kills that possibility.

PIC irq_ack doesn't clear timer IRQ, because timer interrupt handler
usually set up new timer by writing to ccompare register and thus
clearing timer IRQ. However timer may not be set up in the IRQ handler,
e.g. with tickless idle on SMP, or when CPU is going offline, leaving
timer IRQ raised and making do_interrupt attempting to handle it
forever.
To fix this always write current value of ccompare SR chosen to be linux
timer back to that SR on entry to timer interrupt handler.

- set up irq registers and call irq_enter/irq_exit once for each kernel
entry due to interrupt;
- don't attempt to clear current IRQ in the do_interrupt, IRQ handler
will take care of it;
- find pending interrupt with highest priority before every ISR
invocation.

Previously the custom GPIO header for the S3C24xx would in turn
bring in the custom pin control implementation from
<plat/gpio-cfg.h>. This is not good as it mixes up two
subsystems and makes the dependencies hard to track. Make
the dependency explicit by explicitly including the pin
control header where needed.

When refactoring and breaking out the includes for the
machine-specific GPIO configuration, two files were created
in <linux/platform_data/gpio-samsung-s3c[24|64]xx.h>, but as
that namespace shall be used for defining data exchanged
between machines and drivers, using it for these broad macros
and config settings is wrong.
Move the headers back into the machine-local
<mach/gpio-samsung.h> file and think about the next step.

git://git.linaro.org/people/daniel.lezcano/linux into timers/core
Pull clocksource/clockevent updates from Daniel Lezcano:
* Axel Lin removed an unused structure defining the ids for the
bcm kona driver.
* Ezequiel Garcia enabled the timer divider only when the 25MHz
timer is not used for the armada 370 XP.
* Jingoo Han removed a pointless platform data initialization for
the sh_mtu and sh_mtu2.
* Laurent Pinchart added the clk_prepare/clk_unprepare for sh_cmt.
* Linus Walleij added a useful warning in clk_of when no clocks
are found while the old behavior was to silently hang at boot time.
* Maxime Ripard added the high speed timer drivers for the
Allwinner SoCs (A10, A13, A20). He increased the rating, shared the
irq across all available cpus and fixed the clockevent's irq
initialization for the sun4i.
* Michael Opdenacker removed the usage of the IRQF_DISABLED for the
all the timers driver located in drivers/clocksource.
* Stephen Boyd switched to sched_clock_register for the
arm_global_timer, cadence_ttc, sun4i and orion timers.
