While the OLPC display appears to be able to handle either positive
or negative sync, the Display Controller only recognises positive sync.
This brings viafb (for XO-1.5) in line with lxfb (for XO-1) and
fixes a recent regression where the XO-1.5 DCON could no longer be
frozen. Thanks to Florian Tobias Schandinat for helping identify
the fix.
Test case: from a vt,
echo 1 > /sys/devices/platform/dcon/freeze
should cause the current screen contents to freeze, rather than garbage being
displayed.

Current code calculates scaling factors for video overlays even when the
overlays are not scaled. Change the code to skip calculations when not
scaling.
This optimizes the code a bit, but also fixes a problem when configuring
an overlay for a disabled display: if the display is disabled we don't
necessarily know the pixel clock used when the display is enabled, and
in some cases (like HDMI) the pixel clock is set to zero until a proper
video mode is set later. A wrong pixel clock will mess up the
scaling calculations, causing an error like:
omapdss DISPC error: failed to set up scaling, required fclk rate = 0
Hz, current fclk rate = 170666666 Hz
A proper fix would be to check later whether the clocks are enough for the
scaling, at the point when the overlay or display is actually enabled,
but this patch removes the problem for now.

hdmi_get_pixel_clock() returns the pixel clock in Hz, but the pck is
stored as kHz. This means the return value has to be multiplied by 1000,
not by 10000 as the code did.

They were getting this implicitly by an include of module.h
from device.h -- but we are going to clean that up and break
that include chain, so include module.h explicitly now.

of explicitly including something for EXPORT_SYMBOL went unnoticed.
Since we are heading to fix things up and clean module.h from the

This tries to clear up the confusion between integers and iomem pointers
in the marvell pxa platform. MMIO addresses are supposed to be __iomem*
values, in order to let the Linux type checking work correctly. This
patch moves the cast to __iomem as far back as possible, to the place
where the MMIO virtual address windows are defined.

The regulator support in the l4f00242t03 is very non-idiomatic. Rather
than requesting the regulators based on the device name and the supply
names used by the device the driver requires boards to pass system
specific supply names around through platform data. The driver also
conditionally requests the regulators based on this platform data, adding
unneeded conditional code to the driver.
Fix this by removing the platform data and converting to the standard
idiom, also updating all in tree users of the driver. As no datasheet
appears to be available for the LCD I'm guessing the names for the
supplies based on the existing users and I've no ability to do anything
more than compile test.
The use of regulator_set_voltage() in the driver is also problematic,
since fixed voltages are required the expectation would be that the
voltages would be fixed in the constraints set by the machines rather than
manually configured by the driver, but is less problematic.

Add zorder support on OMAP4, this feature allows deciding the visibility order
of the overlays based on the zorder value provided as an overlay info parameter
or a sysfs attribute of the overlay object.
Use the overlay cap OMAP_DSS_OVL_CAP_ZORDER to determine whether zorder is
supported for the overlay or not. Use dss feature FEAT_ALPHA_FREE_ZORDER
if the caps are not available.
Ensure that all overlays that are enabled and connected to the same manager
have different zorders. Swapping zorders of 2 enabled overlays currently
requires disabling one of the overlays.

On OMAP3, in order to enable alpha blending for LCD and TV managers, we needed
to set LCDALPHABLENDERENABLE/TVALPHABLENDERENABLE bits in DISPC_CONFIG. On
OMAP4, alpha blending is always enabled by default, if the above bits are set,
we switch to an OMAP3 compatibility mode where the zorder values in the pipeline
attribute registers are ignored and a fixed priority is configured.
Rename the manager_info member "alpha_enabled" to "partial_alpha_enabled" for
more clarity. Introduce two dss_features FEAT_ALPHA_FIXED_ZORDER and
FEAT_ALPHA_FREE_ZORDER which represent OMAP3-alpha compatibility mode and OMAP4
alpha mode respectively. Introduce an overlay cap for ZORDER. The DSS2 user is
expected to check for the ZORDER cap, if an overlay doesn't have this cap, the
user is expected to set the parameter partial_alpha_enabled. If the overlay has
ZORDER cap, the DSS2 user can assume that alpha blending is already enabled.
Don't support OMAP3 compatibility mode for now. Trying to read/write to
alpha_blending_enabled sysfs attribute issues a warning for OMAP4 and does not
set the LCDALPHABLENDERENABLE/TVALPHABLENDERENABLE bits.
Change alpha_enabled to partial_alpha_enabled in the omap_vout driver. Use
overlay cap "OMAP_DSS_OVL_CAP_GLOBAL_ALPHA" to check if overlay supports alpha
blending or not. Replace this with checks for VIDEO1 pipeline.

overlay_info struct, used to configure overlays, currently includes both
physical and virtual addresses for the pixels. The vaddr was added to
support more exotic configurations where CPU would be used to update a
display, but it is not currently used and there has been no interest in
the feature. Using CPU to update a screen is also less interesting now
that OMAP4 has two LCD outputs.
This patch removes the vaddr field, and modifies the users of omapdss
accordingly. This makes the use of omapdss a bit simpler, as the user
doesn't need to think if it needs to give the vaddr.

This is a driver for N800's display, ported from the old omapfb. This is
a slightly lighter version of the driver as not all features of the old
driver can be ported without big changes to DSS2, and also because some
of the HW features used in the old driver are unclear (e.g. the power
management part).
That said, the new driver works fine for basic use.
Architecturally the driver is not as neat as it could be. N800's display
HW consists of a display buffer chip and a panel, and ideally they would
be represented by separate, independent drivers. This is not currently
possible, and this driver contains both buffer chip and panel driver.

Taal panel driver supports two kinds of backlight control: 1) using DSI
commands sent to the panel to control the backlight, 2) calling function
pointers going to the board file to control the backlight.
The second option is a bit hacky, and will no longer be needed when the
PWM driver supports the backlight features. After that we can use the
standard PWM backlight driver.
This patch removes the second backlight control mechanism, and adds a
boolean field, use_dsi_backlight, to nokia_dsi_panel_data which the
board file can use to inform whether the panel driver should use DSI
commands to control the backlight.

The function calc_fclk_five_taps() uses a fixed value of pixels per line which
is used in calculations to get the minimum fclk needed for scaling with five
taps to work.
Remove this by providing the width of the panel connected to the manager.

dispc_mgr_pclk_rate() is used to calculate minimum required functional clock for
scaling in calc_fclk() and calc_fclk_five_taps(). This function returns the
correct pixel clock for LCD and LCD2 managers, but not for TV manager. Extend
this function so that it gets the correct pixel clock for TV manager.
This also prevents the crash we get when we try to scale overlays connected to
TV manager. The current code leads to a BUG() being executed if we call
dispc_mgr_pclk_rate() for the TV manager.

dispc_ovl_enable_replication() and dispc_ovl_set_fifo_threshold() are currently
called in configure_overlay(). These are the only functions which cause DISPC
register writes of overlay parameters outside of dispc_ovl_setup().
Move these to dispc_ovl_setup() and pass replication, fifo_low and fifo_high
thresholds as arguments to dispc_ovl_setup() in order to be aligned with other
overlay parameters. No functional changes are made.

dispc_ovl_setup() currently takes a large number of overlay arguments, most of
these are members of the overlay_info struct. Replace these arguments by
passing a overlay_info pointer instead.
In configure_overlay(), we create an overlay_info struct called new_oi, this is
a copy of the overlay cache's overlay_info member. Update the new_oi parameters
which could have been possibly changed in configure_overlay(). Pass its pointer
pointer to dispc_ovl_setup().

Use the new read_edid() function to get EDID information from the
display (when available), and use the information to use a suitable mode
at initialization time.
Hot-plug is not yet supported, so the timings selected at init time will
stay even if the monitor would be changed.

We have currently panel-generic-dpi driver, which is a combined driver
for dummy panels and also for DVI output.
The aim is to split the panel-generic-dpi into two, one for fixed size
dummy panels connected via DPI, and the other (this) for variable
resolution output which supports DDC channel (in practice a DVI framer
chip connected to DPI output).

Implement detect() by checking the hot plug detect status.
The implementation is not very good, as it always turns on the HDMI
output to get the detection working. HDMI driver needs improvements so
that we could enable only core parts of it.

check_timings() is supposed to be used to verify if timings are ok or
not. Currently the HDMI driver prints error messages if the timings are
not ok. This is not right, as it is no error to give invalid timings to
check_timings().
Remove the error prints.
