Adding DVI support to OMAP4 PandaBoard.

PandaBoard uses TFP410 DVI Framer chip
http://focus.ti.com/lit/ds/symlink/tfp410.pdf

The TFP410 gets its power enable and display data over GPIO lines muxed
in from OMAP4430. PandaBoard supports other LCD displays through
expansion
connectors, following board rework. This will disable the DVI interface.
However, the existing mux settings remain the same

PandaBoard additionally supports display over HDMI interface. It is
mutually exclusive to display over DVI. Hence the mux settings need to
be
configured seperately, as and when HDMI is enabled

Also, I2C3 bus used for reading EDID data from DVI Monitors is
registered here. Since the design is similar to BeagleBoard, the code
for the same is taken from the kernel.org commit e3333f48
(omap: Adding beagle i2c eeprom driver to read EDID)

The SMSC 3320 USB PHY on the OMAP4 Pandaboard needs a 19.2 MHz
reference clock. This clock is provided from the OMAP4's fref_clk3
pad.

Recent changes to clock44xx_data.c made the clock framework aware
of the existence of these fref_clk[i] lines. If the option
CONFIG_OMAP_RESET_CLOCKS is enabled in the kernel, then the
clock framework will turn these clocks off during bootup.

Explicitly request and keep this clock enabled at init for the
Pandaboard, so that the PHY receives this clock at all times.

Split omap2_init_common_hw() into two functions.  The first,
omap2_init_common_infrastructure(), initializes the hwmod code and
data, the OMAP PM code, and the clock code and data.  The second,
omap2_init_common_devices(), handles any other early device
initialization that, for whatever reason, has not been or cannot be
moved to initcalls or early platform devices.

This patch is required for the hwmod postsetup patch, which allows
board files to change the state that hwmods should be placed into at
the conclusion of the hwmod _setup() function.  For example, for a
board whose creators wish to ensure watchdog coverage across the
entire kernel boot process, code to change the watchdog's postsetup
state will be added in the board-*.c file between the
omap2_init_common_infrastructure() and omap2_init_common_devices() function
calls.

to fix card detection for PandaBoard, unfortunately, the fix missed
to initialize .gpio_cd member of omap2_hsmmc_info. This results

On PandaBoard, the side effect of this is that GPIO line 0 controls
the powering TFP410 DVI chip, and without the fix DVI chip is
inadvertently powered.

Implement GPIO as a platform device.

GPIO APIs are used in machine_init functions. Hence it is
required to complete GPIO probe before board_init. Therefore
GPIO device register and driver register are implemented as
postcore_initcalls.

omap_gpio_init() does nothing now and this function would be
removed in the next patch as it's usage is spread across most
of the board files.

Inorder to convert GPIO as platform device, modifications are
required in clockxxxx_data.c file for OMAP1 so that device names
can be used to obtain clock instead of getting clocks by
name/NULL ptr.

Use runtime pm APIs (pm_runtime_put*/pm_runtime_get*) for enabling
or disabling the clocks, modify sysconfig settings and remove usage
of clock FW APIs.
Note 1: Converting GPIO driver to use runtime PM APIs is not done as a
separate patch because GPIO clock names are different for various OMAPs
and are different for some of the banks in the same CPU. This would need
usage of cpu_is checks and bank id checks while using clock FW APIs in
the gpio driver. Hence while making GPIO a platform driver framework,
PM runtime APIs are used directly.

Note 2: While implementing GPIO as a platform device, pm runtime APIs
are used as mentioned above and modification is not done in gpio's
prepare for idle/ resume after idle functions. This would be done
in the next patch series and GPIO driver would be made to use dev_pm_ops
instead of sysdev_class in that series only.

Due to the above, the GPIO driver implicitly relies on
CM_AUTOIDLE = 1 on its iclk for power management to work, since the
driver never disables its iclk.
This would be taken care in the next patch series (see Note 3 below).

Refer to
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg39112.html
for more details.

Note 3: only pm_runtime_get_sync is called in gpio's probe() and
pm_runtime_put* is never called. This is to make the implementation
similar to the existing GPIO code. Another patch series would be sent
to correct this.

In OMAP3 and OMAP4 gpio's debounce clocks are optional clocks. They
are enabled/ disabled whenever required using clock framework APIs

TODO:
1. Cleanup the GPIO driver. Use function pointers and register
offest pointers instead of using hardcoded values
2. Remove all cpu_is_ checks and OMAP specific macros
3. Remove usage of gpio_bank array so that only
   instance specific information is used in driver code
4. Rename 'method'/ avoid it's usage
5. Fix the non-wakeup gpios handling for OMAP2430, OMAP3 & OMAP4
6. Modify gpio's prepare for idle/ resume after idle functions
   to use runtime pm implentation.

Only OMAP2+ platforms have the System Control Module (SCM) IP block.
In the past, we've kept the SCM header file in plat-omap.  This has
led to abuse - device drivers including it; includes being added that
create implicit dependencies on OMAP2+ builds; etc.

In response, move the SCM headers into mach-omap2/.

As part of this, remove the direct SCM access from the OMAP UDC
