drivers/video: fsl-diu-fb: remove broken screen blanking support · 1738f6f8

Timur Tabi authored Sep 28, 2011

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.

drivers/video: fsl-diu-fb: move some definitions out of the header file · b715f9f0

Timur Tabi authored Sep 28, 2011

Move several macros and structures from the Freescale DIU driver's header
file into the source file, because they're only used by that file. Also
delete a few unused macros.

The diu and diu_ad structures cannot be moved because they're being used
by the MPC5121 platform file. A future patch eliminate the need for
the platform file to access these structs, so they'll be moved also.

drivers/video: fsl-diu-fb: fix some ioctls · 36b0b1d4

Timur Tabi authored Oct 04, 2011

Use the _IOx macros to define the ioctl commands, instead of hard-coded
numbers.  Unfortunately, the original definitions of MFB_SET_PIXFMT and
MFB_GET_PIXFMT used the wrong value for the size, so these macros have
new values now.  To avoid breaking binary compatibility with older
applications, we retain support for the original values, but the driver
displays a warning message if they're used.

Also remove the FBIOGET_GWINFO and FBIOPUT_GWINFO ioctls.  FBIOPUT_GWINFO
was never implemented, and FBIOGET_GWINFO was never used by any
application.

video: da8xx-fb: Increased resolution configuration of revised LCDC IP · 4d740801

Manjunathappa, Prakash authored Jul 18, 2011

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.

mx3fb: fix NULL pointer dereference in screen blanking. · 8b53b7fb

Wolfram Stering authored Sep 23, 2011

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.

video: irq: Remove IRQF_DISABLED · f8798ccb

Yong Zhang authored Sep 22, 2011

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.

smscufx: change edid data to u8 instead of char · 261e7676

Dan Carpenter authored Sep 21, 2011

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.
