fbdev: bfin-t350mcqb-fb: fix fbmem allocation with blanking lines

2010-05-26T21:29:14+00:00

commit de145b44b95b9d3212a82d1c0f29b09778ef33c5 upstream.

The current allocation does not include the memory required for blanking
lines.  So avoid memory corruption when multiple devices are using the DMA
memory near each other.

efifb: fix framebuffer handoff

2010-04-01T22:58:13+00:00

commit 89f3f2199084a160a3a45fa6d9af235696321758 upstream.

Commit 4410f3910947dcea8672280b3adecd53cec4e85e ("fbdev: add support for
handoff from firmware to hw framebuffers") didn't add fb_destroy
operation to efifb.  Fix it and change aperture_size to match size
passed to request_mem_region.

mx3fb: some debug and initialisation fixes

2010-02-09T12:51:00+00:00

commit b3cb53721890879d7bde31f5f9eefd4edf41ab64 upstream.

Fix the kernel oops when dev_dbg is called with mx3_fbi->txd == NULL

Fix the late initialisation of mx3fb->backlight_level.  If not, in the
chain of function started by init_fb_chan(), in __blank() call
sdc_set_brightness(mx3fb, mx3fb->backlight_level) that will shut down the
CONTRAST PWM output.

imxfb: correct location of callbacks in suspend and resume

2010-02-09T12:51:00+00:00

commit 1ec562035ba64e724652cb12b8a770b3906e9bf5 upstream.

The probe function passes a pointer to a struct fb_info to
platform_set_drvdata(), so don't interpret the return value of
platform_get_drvdata() as a pointer to struct imxfb_info.

The original imxfb_info *fbi backlight_power was NULL but in imxfb_suspend
it was 4 resulting in an oops as imxfb_suspend calls
imxfb_disable_controller(fbi) which in turn has

	if (fbi->backlight_power)
			fbi->backlight_power(0);

revert "drivers/video/s3c-fb.c: fix clock setting for Samsung SoC Framebuffer"

2010-01-22T23:17:59+00:00

commit eb29a5cc0b601c458bae9df2f6c3696d75c2d383 upstream.

Fix divide by zero and broken output.  Commit 600ce1a0fa ("fix clock
setting for Samsung SoC Framebuffer") introduced a mandatory refresh
parameter to the platform data for the S3C framebuffer but did not
introduce any validation code, causing existing platforms (none of which
have refresh set) to divide by zero whenever the framebuffer is
configured, generating warnings and unusable output.

Ben Dooks noted several problems with the patch:

 - The platform data supplies the pixclk directly and should already
   have taken care of the refresh rate.
 - The addition of a window ID parameter doesn't help since only the
   root framebuffer can control the pixclk.
 - pixclk is specified in picoseconds (rather than Hz) as the patch
   assumed.

and suggests reverting the commit so do that.  Without fixing this no
mainline user of the driver will produce output.

matroxfb: fix problems with display stability

2009-12-18T22:05:32+00:00

commit 8c651311a3a08c1e4815de6933e00a760e498dae upstream.

Regression caused in 2.6.23 and then despite repeated requests never fixed
or dealt with (Petr promised to sort it in 2008 but seems to have
forgotten).

Enough is enough - remove the problem line that was added.  If it upsets
someone they've had two years to deal with it and at the very least it'll
rattle their cage and wake them up.

VIDEO: Correct use of request_region/request_mem_region

2009-12-02T23:58:32+00:00

request_region should be used with release_region, not request_mem_region.

Geert Uytterhoeven pointed out that in the case of drivers/video/gbefb.c,
the problem is actually the other way around; request_mem_region should be
used instead of request_region.

The semantic patch that finds/fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// 
@r1@
expression start;
@@

request_region(start,...)

@b1@
expression r1.start;

request_mem_region(start,...)

@depends on !b1@
expression r1.start;

- release_mem_region
+ release_region
