omapfb requires the panels to have been probed before omapfb's probe. We
currently manage that by having omapfb in late initcall level. However,
a much simpler way is to just change the makefile so that omapfb is
after the panel drivers.

Commit 100c826235 (OMAPDSS: DPI: use new
clock calculation code) breaks dpi.c compilation if DSI is not enabled
in the kernel configuration.
Fix compilation by adding dummy inline functions for the ones that dpi.c
references. The functions will never be called, as dpi.c knows that
there is no DSI device available.

The 'load_new_rom_data' was used for checking whether new ROM data should
be updated or not.
However, we can decide it with 'size_program' data. If the size is
greater than 0, it means updating ROM area is required. Otherwise, the
default ROM data will be used. Therefore, this duplicate platform data
can be removed.

The brightness of LP855x devices is controlled by I2C register or PWM
input . This mode was selected through the platform data, but it can be
chosen by the driver internally without platform data configuration.
How to decide the control mode:
If the PWM period has specific value, the mode is PWM input.
On the other hand, the mode is register-based.
This mode selection is done on the _probe().
Move 'mode' from a header file to the driver private data structure,
'lp855 x'. And correlated code was replaced.

Platform LCD devices may need to do some device-specific initialization
before they can be used (regulator or GPIO setup, for example), but
currently the driver does not support any way of doing this. This patch
adds a probe() callback to plat_lcd_data which platform LCD devices can
set to indicate that device-specific initialization is needed.

This is my example conversion of a few existing mmap users. The
fb_mmap() case is a good example because it is a bit more complicated
than some: fb_mmap() mmaps one of two different memory areas depending
on the page offset of the mmap (but happily there is never any mixing of
the two, so the helper function still works).

When not using DSI PLL to generate the pixel clock, but DSS FCK, the
possible pixel clock rates are rather limited. DSS FCK is currently used
on OMAP2 and OMAP3.
When using Beagleboard with a monitor that supports high resolutions,
the clock rates do not match (at least for me) for the monitor's pixel
clocks within the current threshold in the code, which is +/- 1MHz.
This patch widens the search up to +/- 15MHz. The search is done in
steps, i.e. it first tries to find a rather exact clock, than a bit less
exact, etc. so this should not change the cases where a clock was
already found.

DSS func clock is calculated with prate / div * m. However, the current
omapdss code calculates it with prate * m / div, which yields a slightly
different result when there's a remainder. For example, 432000000 / 14 *
2 = 61714284, but 432000000 * 2 / 14 = 61714285.
In addition to that, the clock framework wants the clock rate given with
clk_set_rate to be higher than the actual (truncated) end result. So, if
prate is 432000000, and div is 14, the real result is 30857142.8571...
We need to call clk_set_rate with 30857143, which gives us a clock of
30857142. That's why we need to use DIV_ROUND_UP() when calling
clk_set_rate.
This patch fixes the clock calculation.

The Freescale DIU supports a 32x32 color hardware cursor. Framebuffer
cursors are monochrome, so the driver converts the image data to the
format that the DIU expects and then programs to hardware accordingly.
The support cursor enabling/disabling, we provide two cursor image buffers.
One is always blank (all zeroes), and the other contains the real cursor
image data. To disable the cursor (used typically for cursor blinking),
we just tell the hardware to use the blank cursor data.

DISPC on OMAP5 has a more optimised mechanism of asserting Mstandby to achieve
more power savings when DISPC is configured in Smart Standby mode. This
mechanism leads to underflows when multiple DISPC pipes are enabled.

asserting Mstandby. Configure this field to prevent underflows.

When using a DISPC video pipeline to a fetch a NV12 buffer in a 2D container, we
need to set set a doublestride bit in the video pipe's ATTRIBUTES register. This
is needed because the stride for the UV plane(using a 16 bit Tiler container) is
double the stride for the Y plane(using a 8 bit Tiler container) for the 0 or
180 degree views. The ROW_INC register is meant for the Y plane, and the HW will
calculate the row increment needed for the UV plane by using double the stride
value based on whether this bit is set or not.
Set the bit when we are using a 2D Tiler buffer and when rotation is 0 or 180
degrees. The stride value is the same for 90 and 270 degree Tiler views, hence
the bit shouldn't be set.

Each version of OMAP has a limitation on the maximum pixel clock frequency
supported by an overlay manager. This limit isn't checked by omapdss. Add
dispc feats for lcd and tv managers and check whether the target timings can
be supported or not.
The pixel clock limitations are actually more complex. They depend on which OPP
OMAP is in, and they also depend on which encoder is the manager connected to.
The OPP dependence is ignored as DSS forces the PM framework to be on OPP100
when DSS is enabled, and the encoder dependencies are ignored by DISPC for now.
These limits should come from the encoder driver.
The OMAP2 TRM doesn't mention the maximum pixel clock limit. This value is left
as half of DSS_FCLK, as OMAP2 requires the PCD to be atleast 2.
