omapdss has its own video-timings struct, but we want to move the common
videomode.
The first step is to change the omapdss's pixelclock unit from kHz to
Hz. Also, omapdss uses "pixel_clock" field name, whereas the common
videomode uses "pixelclock" field name. This patch changes the field
name also, as that makes it easy to spot any non-converted pixel_clock
uses.

Remove firmware framebuffer before initializing hyperv-fb. Needed
on gen2 virtual machines. Letting register_framebuffer handle the
switchover results in efifb still being active while hyperv graphics
are initialized, which in turn can make the linux kernel hang.

UEFI-based generation 2 virtual machines support vmbus devices only.
There is no pci bus. Thus they use a different mechanism for the
graphics framebuffer: Instead of using the vga pci bar a chunk of
memory muct be allocated from the hyperv mmio region declared using
APCI. This patch implements support for it.

Instead of relying on the OMAP specific
omap_pm_get_dev_context_loss_count() to detect register context loss, we
can achieve the same in a much simpler way by just observing the DISPC
registers.
We always set DISPC's load mode to LOAD_FRAME_ONLY, which is not the
reset value. Thus we can just observe the load mode to see if we have
lost register context.

Some fields in platform data structure is never used by boards.
This patch removes these fields and as a result optimizes private
driver structure a bit. Additionally patch removes backligh_power()
callback, so if it will be needed in the future, this feature should
be added as pwm{gpio,etc.}-regulator to the board code or in the DTS.

The driver uses DIV_ROUND_UP when calculating decimated width & height.
For example, when decimating with 3, the width is calculated as:
width = DIV_ROUND_UP(width, decim_x);
This yields bad results for some values. For example, 800/3=266.666...,
which is rounded to 267. When the input width is set to 267, and pixel
increment is set to 3, this causes the dispc to read a line of 801
pixels, i.e. it reads a wrong pixel at the end of the line.
Even more pressing, the above rounding causes a BUG() in pixinc(), as
the value of 801 is used to calculate row increment, leading to a bad
value being passed to pixinc().
This patch fixes the decimation by removing the DIV_ROUND_UP()s when
calculating width and height for decimation.

In tgafb there is a restriction that prevents the user from setting a
videomode with line length not a multiple of 64 bytes (for example,
800x600 is not allowed).
The reason for this restriction it that functions copyarea_line_8bpp and
copyarea_line_32bpp can not handle a line length that is not a multiple
of 64 bytes.
This patch removes this restriction on mode setting and makes sure that
the functions copyarea_line_8bpp and copyarea_line_32bpp are called only
if line length is a multiple of 64 bytes. If we set a mode 800x600,
the functions copyarea_line_8bpp and copyarea_line_32bpp are not used,
generic functions for copying are used instead and it works just fine.

The functions for data copying copyarea_foreward_8bpp and
copyarea_backward_8bpp are buggy, they produce screen corruption.
This patch fixes the functions and moves the logic to one function
"copyarea_8bpp". For simplicity, the function only handles copying that
is aligned on 8 pixes. If we copy an unaligned area, generic function
cfb_copyarea is used.

Mode setting in the TGA driver is broken for these reasons:
- info->fix.line_length is set just once in tgafb_init_fix function. If
we change videomode, info->fix.line_length is not recalculated - so
the video mode is changed but the screen is corrupted because of wrong
info->fix.line_length.
- info->fix.smem_len is set in tgafb_init_fix to the size of the default
video mode (640x480). If we set a higher resolution,
info->fix.smem_len is smaller than the current screen size, preventing
the userspace program from mapping the framebuffer.
This patch fixes it:
- info->fix.line_length initialization is moved to tgafb_set_par so that
it is recalculated with each mode change.
- info->fix.smem_len is set to a fixed value representing the real
amount of video ram (the values are taken from xfree86 driver).
- add a check to tgafb_check_var to prevent us from setting a videomode
that doesn't fit into videoram.
- in tgafb_register, tgafb_init_fix is moved upwards, to be called
before fb_find_mode (because fb_find_mode already needs the videoram
size set in tgafb_init_fix).

This patch fixes the hardware cursor on mach64 when font width is not a
multiple of 8 pixels.
If you load such a font, the cursor is expanded to the next 8-byte
boundary and a part of the next character after the cursor is not
visible.
For example, when you load a font with 12-pixel width, the cursor width
is 16 pixels and when the cursor is displayed, 4 pixels of the next
character are not visible.
The reason is this: atyfb_cursor is called with proper parameters to
load an image that is 12-pixel wide. However, the number is aligned on
the next 8-pixel boundary on the line
"unsigned int width = (cursor->image.width + 7) >> 3;" and the whole
function acts as it is was loading a 16-pixel image.
This patch fixes it so that the value written to the framebuffer is
padded with 0xaaaa (the transparent pattern) when the image size it not
a multiple of 8 pixels. The transparent pattern causes that the cursor
will not interfere with the next character.

This patch fixes mach64 to use unaligned access to the font bitmap.
This fixes unaligned access warning on sparc64 when 14x8 font is loaded.
On x86(64), unaligned access is handled in hardware, so both functions
le32_to_cpup and get_unaligned_le32 perform the same operation.
On RISC machines, unaligned access is not handled in hardware, so we
better use get_unaligned_le32 to avoid the unaligned trap and warning.

The function cfb_copyarea is buggy when the copy operation is not aligned on
long boundary (4 bytes on 32-bit machines, 8 bytes on 64-bit machines).
How to reproduce:
- use x86-64 machine
- use a framebuffer driver without acceleration (for example uvesafb)
- set the framebuffer to 8-bit depth
(for example fbset -a 1024x768-60 -depth 8)
- load a font with character width that is not a multiple of 8 pixels
note: the console-tools package cannot load a font that has
width different from 8 pixels. You need to install the packages
"kbd" and "console-terminus" and use the program "setfont" to
set font width (for example: setfont Uni2-Terminus20x10)
- move some text left and right on the bash command line and you get a
screen corruption
To expose more bugs, put this line to the end of uvesafb_init_info:
info->flags |= FBINFO_HWACCEL_COPYAREA | FBINFO_READS_FAST;
- Now framebuffer console will use cfb_copyarea for console scrolling.
You get a screen corruption when console is scrolled.
This patch is a rewrite of cfb_copyarea. It fixes the bugs, with this
patch, console scrolling in 8-bit depth with a font width that is not a
multiple of 8 pixels works fine.
The cfb_copyarea code was very buggy and it looks like it was written
and never tried with non-8-pixel font.

When FB_EVENT_FB_UNBIND is sent, fbcon has two paths, one path taken
when there is another frame buffer to switch any affected vcs to and
another path when there isn't.
In the case where there is another frame buffer to use,
fbcon_fb_unbind calls set_con2fb_map to remap all of the affected vcs
to the replacement frame buffer. set_con2fb_map will eventually call
con2fb_release_oldinfo when the last vcs gets unmapped from the old
frame buffer.
con2fb_release_oldinfo frees the fbcon data that is hooked off of the
fb_info structure, including the cursor timer.
In the case where there isn't another frame buffer to use,
fbcon_fb_unbind simply calls fbcon_unbind, which doesn't clear the
con2fb_map or free the fbcon data hooked from the fb_info
structure. In particular, it doesn't stop the cursor blink timer. When
the fb_info structure is then freed, we end up with a timer queue
pointing into freed memory and "bad things" start happening.
This patch first changes con2fb_release_oldinfo so that it can take a
NULL pointer for the new frame buffer, but still does all of the
deallocation and cursor timer cleanup.
Finally, the patch tries to replicate some of what set_con2fb_map does
by clearing the con2fb_map for the affected vcs and calling the
modified con2fb_release_info function to clean up the fb_info structure.

Fix the following warning in the aty128fb driver:
drivers/video/aty/aty128fb.c:363:12: warning: 'backlight' defined but not used [-Wunused-variable]
static int backlight = 0;
^
as the variable's value is only read if CONFIG_FB_ATY128_BACKLIGHT=y. The
variable is also set if MODULE is unset[*].
[*] I wonder if the conditional wrapper around aty128fb_setup() should be
using CONFIG_MODULE rather than MODULE.
