DISPC functions are modified in order to work when the manager is LCD2.
This includes:
Adding new IRQs specific to LCD2 and their handling.
Provide dumps of the new manager's registers.
Provide dumps of the new manager's clocks.
Checks for channel for registers DISPC_CONTROL2 and DISPC_CONFIG2
which can't be parametrized.

interface drivers
The interface drivers (dsi.c, sdi.c etc) need to call dispc functions with
dssdev->manager->id as a parameter to specify the DISPC channel which they want
to configure/use, this is required as the same functions are now used to configure
dispc registers of different channels.
The following dispc functions are changed to incorporate channel as an argument:
-dispc_enable_fifohandcheck()
-dispc_set_lcd_size()
-dispc_set_parallel_interface_mode()
-dispc_set_tft_data_lines()
-dispc_set_lcd_display_type()
-dispc_set_lcd_timings()

On OMAP4, we have a new DISPC channel for Overlay Manager LCD2. There is a set
of regsiters for LCD2 channel similar to the existing LCD channel, like
DISPC_CONTROL2, DISPC_DIVISOR2, DISPC_CONFIG2 and so on.
Introduce new enum members for LCD2 Channel and corresponding Overlay Manager
in display.h.
Represent the following DISPC register defines with channel as a parameter
to differentiate between LCD and LCD2 registers (and also DIGIT in some cases):
DISPC_DEFAULT_COLOR, DISPC_TRANS_COLOR, DISPC_TIMING_H, DISPC_TIMING_V,
DISPC_POL_FREQ, DISPC_DIVISOR, DISPC_SIZE_LCD, DISPC_DATA_CYCLEk,
DISPC_CPR_COEF_R, DISPC_CPR_COEF_G and DISPC_CPR_COEF_B
This parametrization helps in reducing the number of register defines for DISPC.
Replace the existing reads/writes to these registers in this new way.
Also, Introduce defines for registers DISPC_CONTROL2 and DISPC_CONFIG2 which
are used exclusively for LCD2 channel.

The supported set of color modes varies for different DISPC pipelines(plane)
and omap version. This makes the checks for validation of a color mode more
complicated as new omap versions are added.
A dss_feature function is created which tells if a color_mode is supported
for a plane on the current omap revision.

Generic DPI panel driver includes the driver and 4 similar panel configurations. It
will match the panel name which is passed from platform data and setup the
right configurations.
With generic DPI panel driver, we can remove those 4 duplicated panel display
drivers. In the future, it is simple for us just add new panel configuration
date in panel-generic-dpi.c to support new display panel.

It seems there is a small problem of VGA palette corruption on EFI
machine. When the kernel initializes the architecture, it checks if the
machine is a EFI machine and assumes that a VGA console can exist.
When it initializes the console in vgacon_startup it checks if it can
really use the VGA console. I think this is where a check is missing.
Currently, the function can fail if a VESA boot mode is detected but not if
a EFI boot mode was used.
Thus vgacon_startup() doesn't fail and initialize the video card for a real
VGA mode. This function changes the first 16entries of the VGA palette.
When the efifb driver kicks in, the palette is not restored to default
ramp value, thus the 16 first entry remain in a modified state. The
following patch prevent this corruption.

The reset command is part of the init sequence and it take effect
only if the lcd is powered.
The effect of the bug was that the sequence:
set lcd power_state to FB_BLANK_POWERDOWN
set lcd power_state to FB_BLANK_UNBLANK
Did not produced a complete reboot of the LCD which was showing fuzzy
colours.
This was not experienced before implementing correctly all the LCD power
states with the patch [1]. Since before the patch [1] the regulators were
not touched and the LCD shutdown was reached with a register write. After
the patch [1] a complete boot sequence with an initial reset is needed for
the display every time the LCD is powered up.

Thanks for Ian's review and comments.

The root cause of the panic is the race between the resume and reconnect to the backend.
Clearing the 'update_wanted' flag of xenfb before disconnecting from the
backend fixes this issue.

This adds a driver for the the 2D graphics accelerator found on PXA3xx
processors. Only resource mapping, interrupt handling and a simple ioctl
handler is done by the kernel part, the rest of the logic is implemented
in DirectFB userspace.
Graphic applications greatly benefit for line drawing, blend, and
rectangle and triangle filling operations.
Benchmarks done on a PXA303 using the df_dok benchmarking tool follow,
where the value in square brackets show the CPU usage during that test.

After commit 25edd6946a1d74e5e77813c2324a0908c68bcf9e ("sparc64: Get
rid of indirect p1275 PROM call buffer.") we can't pass virtual
addresses >4GB to PROM calls.
Largely this is never necessary in drivers because we have a copy of
the entire PROM device tree in the kernel and a set of of_*()
interfaces to access it.
Unfortunately there were some lingering prom calls in the atyfb
driver, in particular prom_finddevice() was being called with an
on-stack address which could be anywhere.
This code is actually probing for information we already have, the
PROM choosen console output device is stored in of_console_device so
all of this nasty code consolidates into a one-line comparison.
Next we have some prom_getintdefault() calls which are trivially
transformed into the equivalent of_getintprop_default().
Special thanks to Fabio, who figured out exactly where the bootup
was hanging. That made this bug trivial to fix.

LCDC hardware can support 1920x1080 formats, adjust the driver to cover them.
Besides, instead of guessing some "reasonable" validity checks, only verify
values in .fb_check_var(), that we are sure, we cannot support.

On my system with a radeon x2, the first GPU was not overlapping vesa
but the test decided it was.

An earlier patch replaced open-coded video-mode configuration from
platform data by a call to fb_videomode_to_var(), thereby setting
ofdisplay sizes have been accidentally lost. Restore them.

This kills off all of the dl_xxx() printk wrappers and simply stubs in a
pr_fmt() definition to accomplish the same thing.
