We currently have a single function to enable and disable the manager
output for LCD and DIGIT. The functions are a bit complex, as handling
both enable and disable require some extra steps to ensure that the
output is enabled or disabled properly without errors before exiting the
function.
The code can be made simpler to understand by splitting the functions
into separate enable and disable functions. We'll also clean up the
comments and some parameter names at the same time.

dispc.c's functions to enable LCD and DIGIT outputs can be cleaned up a
bit by using common functions to set the enable bit and to check if the
output is enabled.

dispc_ovl_setup() uses struct omap_overlay to get the caps for the
overlay. We can change the code to get the caps directly from dss
features, thus removing the dependency to struct omap_overlay.

Dispc has a bunch of functions used to configure output related
parameters:
- dispc_mgr_set_io_pad_mode
- dispc_mgr_enable_stallmode
- dispc_mgr_enable_fifohandcheck
- dispc_mgr_set_clock_div
- dispc_mgr_set_tft_data_lines
- dispc_lcd_enable_signal_polarity
- dispc_mgr_set_lcd_type_tft
These are all called together, and the configuration values are taken
from struct dss_lcd_mgr_config.
Instead of exposing those individual dispc functions, create a new one,
dispc_mgr_set_lcd_config(), which is used to configure the above
parameters from values in struct dss_lcd_mgr_config.

When we enable an output we don't check if we need to register the vsync
isr. This causes us to miss vsync interrupts until somebody changes the
configuration of an overlay or an overlay manager.
Add the registration to dss_mgr_enable to fix the problem.

If dsi_get_dsidev_from_id() is called with a DSI module id that does not
exist on the board, the function will crash as omap_dss_get_output()
will return NULL.
This happens on omap3 boards when dumping DSI clocks, as the dumping
code will try to get the dsidev for DSI modules 0 and 1, but omap3 only
has DSI module 0.
Also clean up the id -> output mapping, so that if the function is
called with invalid module ID it will return NULL.

This patch converts vrfb library into a platform device, in an effort to
remove omap dependencies.
The platform device is registered in arch/arm/plat-omap/fb.c and
assigned resources depending on whether running on omap2 or omap3.
The vrfb driver will parse those resources and use them to access vrfb
configuration registers and the vrfb virtual rotation areas.

The printk in DSSDBG function definition is replaced with dynamic debug enabled
pr_debug(). The use of dynamic debugging provides more flexibility as each debug
statement can be enabled or disabled dynamically on basis of source filename,
line number, module name etc., by writing to a control file in debugfs
filesystem. For better understanding please refer to
Documentation/dynamic-debug-howto.txt.
The DSSDBGF() differs from DSSDBG() by providing function name. However,
function name, line number, module name and thread ID can be printed through
dynamic debug by setting appropriate flags 'f','l','m' and 't' in the debugfs
control file. So, DSSDBGF instances are replaced with DSSDBG.

In OMAPDSS the DEBUG flag is set only after the OMAPDSS module is called, for
which the debugging capabilities are available only after its proper
initialization. As a result of which tracking of bugs prior to or during initial

Pull pwm changes from Thierry Reding:
"All legacy PWM providers have now been moved to the PWM subsystem.
The plan for 3.8 is to adapt all board files to provide a lookup table
for PWM devices in order to get rid of the global namespace.
Subsequently, users of the legacy pwm_request() and pwm_free()
functions can be migrated to the new pwm_get() and pwm_put()
functions. Once this has been completed, the legacy API and the
compatibility code in the core can be removed.
In addition to the above, these changes also add support for
configuring the polarity of a PWM signal (currently only supported on
ECAP and EHRPWM) and include a much needed rework of the i.MX driver.
Managed functions to obtain and release a PWM device (devm_pwm_get()
and devm_pwm_put()) have been added and the pwm-backlight driver has
been updated to use them. If the PWM subsystem hasn't been enabled,
dummy functions are provided that allow the subsystem to safely
compile out.
Some common checks on input parameters have been moved to the core and
removed from the drivers. Finally, a small fix corrects the
description of the PWM specifier's second cell in the device tree
representation."

Omapdss driver changes for the 3.7 merge window.
Notable changes:
* Basic writeback support for DISPC level. Writeback is not yet usable, though,
as we need higher level code to actually expose the writeback feature to
userspace.
* Rewriting the omapdss output drivers. We're trying to remove the hard links
between the omapdss and the panels, and this rewrite work moves us closer to
that goal.
* Cleanup and restructuring patches that have been made while working on device
tree support for omapdss. Device tree support is still some way ahead, but
these patches are good cleanups in themselves.
* Basic OMAP5 DSS support for DPI and DSI outputs.
* Workaround for the problem that GFX overlay's fifo is too small for high
resolution scenarios, causing underflows.
* Cleanups that remove dependencies to omap platform code.

nuc900fb_map_video_memory is called by an devinit function
that may be called at run-time, but the function itself is
marked __init and will be discarded after boot.
To avoid calling into a function that may have been overwritten,
mark nuc900fb_map_video_memory itself as __devinit.
Without this patch, building nuc950_defconfig results in:
WARNING: drivers/video/built-in.o(.devinit.text+0x26c): Section mismatch in reference from the function nuc900fb_probe() to the function .init.text:nuc900fb_map_video_memory()
The function __devinit nuc900fb_probe() references
a function __init nuc900fb_map_video_memory().
If nuc900fb_map_video_memory is only used by nuc900fb_probe then
annotate nuc900fb_map_video_memory with a matching annotation.

A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA,
currently it lost original meaning but still has some effects:
| effect | alternative flags
-+------------------------+---------------------------------------------
1| account as reserved_vm | VM_IO
2| skip in core dump | VM_IO, VM_DONTDUMP
3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
4| do not mlock | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP
This patch removes reserved_vm counter from mm_struct. Seems like nobody
cares about it, it does not exported into userspace directly, it only
reduces total_vm showed in proc.
Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP.
remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP.
remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.
