0556dc340e backlight: fix broken regulator API usage in l4f00242t03
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.

The Freescale DIU video controller supports five video "modes", but only

2572df91d5 drivers/video: fsl-diu-fb: use an enum for the AOI index
Each of the five AOIs created by the DIU driver has a special purpose, and
they're not treated equally.  It makes sense to identify them with an enum
instead of a hard-coded number.

Since the 'index' is now an enum, it can only contain allowed values, so
there's no need to check for an invalid value.  This simplifies some other
code, such as fsl_diu_disable_panel(), which no longer needs to return an
error code.

1920x1080x60

Also add margin data to the 320x240 video mode.  This mode was originally
intended only for the AOIs (overlays) used on planes two and three, but with
real margin data, it can now be used as an actual video mode.
Video mode data is from earlier work done by Jerry Huang

1738f6f84f drivers/video: fsl-diu-fb: remove broken screen blanking support
The function which is supposed to provide screen blanking support doesn't
actually do anything, so the framebuffer layer thinks the screen has
been blanked when it really isn't.  Remove the code completely for now.

A side-effect of this change is that the framebuffer console blanking now
works correctly.  Presumably this is because the console now receives -EINVAL
instead of '0' when it asks the driver to blank the screen, so the console
does it manually now.

A signficant refactoring of the driver is planned, and proper hardware
blanking support will added afterwards.

applications, we retain support for the original values, but the driver
displays a warning message if they're used.

4d7408014e video: da8xx-fb: Increased resolution configuration of revised LCDC IP
Revised LCD controller in upcoming TI SoC which is an updated version of
LCDC IP that was found on TI's DA850 SoC supports 2048*2048 resolution.
Below are the encoding details:
Width:
Pixels Per Line = {pplmsb, ppllsb, 4'b1111} + 1
Where pplmsb:1bit==>Raster Timing0[3], ppllsb:6bits==>Raster Timing0[9:4].
And encoded value can range from 16 to 2048 in multiples of 16.

Height:
Lines Per Panel = {lpp_b10, lpp}
Where lpp:10bits==>Raster Timing1[9:0], lpp_b10:1bit==>Raster Timing2[26].
And encoded value can range from 1 to 2048, programmable range is 0 to
2047.

Patch is verified on emulation platform of upcoming SoC for updated
feature and on DA850 platform to make sure nothing existing breaks.

8b53b7fb57 mx3fb: fix NULL pointer dereference in screen blanking.
When blanking an already blanked framebuffer, a kernel NULL pointer
dereference occurred, because mx3fb driver handles all kinds of screen
blanking (normal, vsync suspend, powerdown) in the same way.
Certain programs (Xorg X11 server) first do a normal blank, followed by
a powerdown blank, which triggered the bug.

Add an additional safeguard and make sdc_disable_channel() safe against
multiple calls independent of other logic.

f8798ccbef video: irq: Remove IRQF_DISABLED
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler
returns with interrupts enabled (see commit [b738a50a:
genirq: Warn when handler enables interrupts]).

So now this flag is a NOOP and can be removed.

Having "edid" as char caused a problem in ufx_read_edid() where we
compared "edid[i] != 0xFF".  Because of the type difference, the
condition was never true and the error checking failed.

Also I added a __user notation to silence a sparse complaint.

54128701ec OMAPDSS: DISPC: zorder support for DSS overlays
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.

11354dd58d OMAPDSS/OMAP_VOUT: Fix incorrect OMAP3-alpha compatibility setting
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.

212b0d50e2 OMAPDSS: remove vaddr from overlay info
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.

562a060611 OMAPDSS: Add N800 panel driver
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.
