Kyungmin Park aa3831cf9d ARM: Consolidate the clkdev header files
Now most of ARM machines has the alsmot same __clk_get/put() macro

So place it at the arch/arm/include/asm/clkdev.h and remove the reduntant header files

But some machines don't have the same form as above. It can use the machince specific clkdev file by HAVE_MACH_CLKDEV config

Now there are only 3 caese.

1) define the clk structure with clkdev macro => Need to move clk structure to proper header file

arch/arm/mach-versatile/include/mach/clkdev.h
arch/arm/mach-realview/include/mach/clkdev.h
arch/arm/mach-vexpress/include/mach/clkdev.h
arch/arm/mach-integrator/include/mach/clkdev.h

2) export the __clk_get/put function at clock.c

arch/arm/mach-shmobile/include/mach/clkdev.h

3) demuxing the clk source
arch/arm/mach-u300/include/mach/clkdev.h

Kevin Hilman 80c6d1e65c OMAP: PM: omap_device: add API to disable idle on suspend
By default, omap_devices will be automatically idled on suspend
(and re-enabled on resume.)  Using this new API, device init code
can disable this feature if desired.

NOTE: any driver/device that has been runtime PM converted should
      not be using this API.

Kevin Hilman c03f007a8b OMAP: PM: omap_device: add system PM methods for PM domain handling
In the omap_device PM domain callbacks, use omap_device idle/enable to
automatically manage device idle states during system suspend/resume.

If an omap_device has not already been runtime suspended, the
->suspend_noirq() method of the PM domain will use omap_device_idle()
to idle the HW after calling the driver's ->runtime_suspend()
callback.  Similarily, upon resume, if the device was suspended during
->suspend_noirq(), the ->resume_noirq() method of the PM domain will
use omap_device_enable() to enable the HW and then call the driver's
->runtime_resume() callback.

If a device has already been runtime suspended, the noirq methods of
the PM domain leave the device runtime suspended by default.

However, if a driver needs to runtime resume a device during suspend
(for example, to change its wakeup settings), it may do so using
pm_runtime_get* in it's ->suspend() callback.

Benoit Cousson 03fdefe53a OMAP4: hwmod data: Add modulemode entry in omap_hwmod structure
Add a new field to provide the mode supported by the module.
The mode will control the way mandatory clocks are managed by the PRCM.

  0 : Module is temporarily disabled by SW. OCP access to module are stalled.
      Can be used to change timing parameter of GPMC module.
  1 : Module is managed automatically by HW according to clock domain
      transition. A clock domain sleep transition put module into idle.
      A wakeup domain transition put it back into function.
      If CLKTRCTRL=3, any OCP access to module is always granted.
      Module clocks may be gated according to the clock domain state.
  2 : Module is explicitly enabled. Interface clock (if not used for
      functions) may be gated according to the clock domain state.
      Functional clocks are guarantied to stay present. As long as
      in this configuration, power domain sleep transition cannot happen.

Some modules will have a modulemode initialized at 1 (HWCTRL) by default.
This is the case for interconnect and simple module like GPIO, WDT, MAILBOX.

Benoit Cousson a5322c6f3a OMAP4: hwmod data: Add clock domain attribute
In OMAP PRCM terminology, the clock domain is defined as a group of IPs
that share some clocks and most of the time an interface clock.
Every IP does belong to a clockdomain.
For the moment the clock domain attribute is affected to a clock node.
The issue with that approach, is that a clock might or not belong to a
clock domain. Moreover during module transition, it is up to a module
to handle properly the clock domain state and not to a clock node.

Create a clkdm_name attribute to provide this information per hwmod.

Populate this attribute for every OMAP4 hwmod entries.

Future cleanup series with remove that information from the OMAP4 clock
when it is relevant.

Avinash.H.M 6d3c55fd4f OMAP: hwmod: fix the i2c-reset timeout during bootup
The sequence of _ocp_softreset doesn't work for i2c. The i2c module has a
special sequence to reset the module. The sequence is
 - Disable the I2C.
 - Write to SOFTRESET bit.
 - Enable the I2C.
 - Poll on the RESETDONE bit.
The sequence is implemented as a function and the i2c_class is updated with
the correct 'reset' pointer.  omap_hwmod_softreset function is implemented
which triggers the softreset by writing into sysconfig register. On following
this sequence, i2c module resets properly and timeouts are not seen.

Andy Green 7300272160 I2C: OMAP2+: increase omap_i2c_dev_attr flags from u8 to u32
As part of removing cpu_...() from the OMAP I2C driver, we need to
convert the CPU tests into functionality flags that are set by
hwmod class in the same way the IP revision is.

More flags are needed than will fit in the existing u8 flags
member of omap_i2c_dev_attr.

These flags can refer to options inside the IP block but they are
most needed for information about cpu implementation specific
options that are not part of the IP block itself.  For example,
how the CPU data bus is wired to the IP block databus differs
between OMAP cpus and affects how you must shift the address in
the IP block, but is not a feature of the IP block itself.

Benoit Cousson 724019b013 OMAP2+: hwmod: Fix smart-standby + wakeup support
The commit 86009eb326 was adding
the wakeup support for new OMAP4 IPs. This support is incomplete for
busmaster IPs that need as well to use smart-standby with wakeup.

This new standbymode is suported on HSI and USB_HOST_FS for the moment.

Add the new MSTANDBY_SMART_WKUP flag to mark the IPs that support this
capability.

Enable this new mode when applicable in _enable_wakeup, _disable_wakeup,
_enable_sysc and _idle_sysc.

The omap_hwmod_44xx_data.c will have to be updated to add this new flag.

Misael Lopez Cruz f19b2823f8 mfd: twl6040: Add initial support
TWL6040 IC provides analog high-end audio codec functions for
handset applications. It contains several audio analog inputs
and outputs as well as vibrator support. It's connected to the
host processor via PDM interface for audio data communication.
The audio modules are controlled by internal registers that
can be accessed by I2C and PDM interface.

TWL6040 MFD will be registered as a child of TWL-CORE, and will
have two children of its own: twl6040-codec and twl6040-vibra.

This driver is based on TWL4030 and WM8350 MFD drivers.

Grazvydas Ignotas 7a559c7882 omap: cleanup NAND platform data
omap_nand_platform_data fields 'options', 'gpio_irq', 'nand_setup' and
'dma_channel' are never referenced by the NAND driver, yet various
board files are initializing those fields. This is both incorrect and
confusing, so remove them. This allows to get rid of a global
variable in gpmc-nand.c.

This also corrects an issue where some boards are trying to pass NAND
16bit flag through .options, but the driver is using .devsize instead
and ignoring .options.

Finally, .dev_ready is treated as a flag by the driver, so make it bool
instead of a function pointer.

Tony Lindgren e74984e46e omap: Set separate timer init functions to avoid cpu_is_omap tests
This is needed for the following patches so we can initialize the
rest of the hardware timers later on.

As with the init_irq calls, there's no need to do cpu_is_omap calls
during the timer init as we only care about the major omap generation.
This means that we can initialize the sys_timer with the .timer
entries alone.

Note that for now we just set stubs for the various sys_timer entries
that will get populated in a later patch. The following patches will
also remove the omap_dm_timer_init calls and change the init for the
rest of the hardware timers to happen with an arch_initcall.

Kevin Hilman e5ff4440cf gpio/omap: cleanup show revision, remove cpu_is checks, display only once
Remove cpu_is_* checks from gpio_show_revision() by passing in the
revision address offset from platform data.  SoCs with no revision
register (15xx, 7xx, and all MPUIOs) use -1 (actually, USHRT_MAX) to
signify no register.

While here, all GPIO banks are assumed to be the same revision, so fix
show_revision() to only show the revision for the first bank it finds.
This removes duplicate GPIO revision prints during boot.

Thanks to Charulatha V <charu@ti.com> for finding/fixing a few -1s
that were missed in the original patch.
