afa9b649aa fbcon: prevent cursor disappearance after switching to 512 character font
Adjust and honor the vc_scrl_erase_char for 256 and 512 character fonts.

It fixes the issue with disappearing cursor during scrolling
(http://bugzilla.kernel.org/show_bug.cgi?id=11258).  The issue was
reported and tracked by Peter Hanzel.

ea757acad5 atmel_lcdfb: add board parameter specify framebuffer memory size
Specify how much physically continuous, DMA capable memory will be
allocated at driver initialization time.  This allow to create framebuffer
device with larger virtual resolution.  Combine with y-panning this can be
used to implement double buffering acceleration method.

e730d8b0a5 atmel_lcdfb: set ypanstep to 1 and enable y-panning on AT91
Panning in the y-direction can be done by simply changing the DMA base
address.  This code is already in place, but FBIOPAN_DISPLAY will
currently fail because ypanstep is 0.

Set ypanstep to 1 to indicate that we do support y-panning and also set
the necessary acceleration flags on AT91 (AVR32 already have them.)

969830b2fe radeonfb: fix accel engine hangs
Some chips appear to have the 2D engine hang during screen redraw,
typically in a sequence of copyarea operations. This appear to be
solved by adding a flush of the engine destination pixel cache
and waiting for the engine to be idle before issuing the accel
operation. The performance impact seems to be fairly small.

Here is a trace on an RV370 (PCI device ID 0x5b64), it records the
RBBM_STATUS register, then the source x/y, destination x/y, and
width/height used for the copy:

----------------------------------------
radeonfb_prim_copyarea: STATUS[00000140] src[210:70] dst[210:60] wh[a0:10]
radeonfb_prim_copyarea: STATUS[00000140] src[2b8:70] dst[2b8:60] wh[88:10]

radeonfb_prim_copyarea: STATUS[80026133] src[e8:80] dst[e8:70] wh[80:10]
radeonfb_prim_copyarea: STATUS[8002612d] src[170:80] dst[170:70] wh[30:10]

radeonfb_prim_copyarea: STATUS[8002611b] src[248:80] dst[248:70] wh[68:10]
----------------------------------------

When things are going fine the copies complete before the next ROP is
even issued, but all of a sudden the 2D unit becomes active (bit 17 in
RBBM_STATUS) and the FIFO retry (bit 13) and FIFO pipeline busy (bit
14) are set as well.  The FIFO begins to backup until it becomes full.

What happens next is the radeon_fifo_wait() times out, and we access
the chip illegally leading to a bus error which usually wedges the
box.  None of this makes it to the console screen, of course :-)
radeon_fifo_wait() should be modified to reset the accelerator when
this timeout happens instead of programming the chip anyways.

Ker:xnel panic - not syncing: Irrecoverable deferred error trap.
----------------------------------------

Another quirk is that these copyarea calls will not happen until the
first drivers/char/vt.c:redraw_screen() occurs.  This will only happen
if you 1) VC switch or 2) run "consolechars" or 3) unblank the screen.

This seems to happen because until a redraw_screen() the screen scrolling
method used by fbcon is not finalized yet.  I've seen this with other fb
drivers too.

So if all you do is boot straight into X you will never see this bug on
the relevant chips.

Yes, the fourth bit should be "blinking", but since we cannot reasonably

efc4918143 radeon: misc corrections
I have a new PCI-E radeon RV380 series card (PCI device ID 5b64) that
hangs in my sparc64 boxes when the init scripts set the font.  The problem
goes away if I disable acceleration.

I haven't figured out that bug yet, but along the way I found some
corrections to make based upon some auditing.

1) The RB2D_DC_FLUSH_ALL value used by the kernel fb driver
   and the XORG video driver differ.  I've made the kernel
   match what XORG is using.

2) In radeonfb_engine_reset() we have top-level code structure
   that roughly looks like:

	if (family is 300, 350, or V350)
		do this;
	else
		do that;
	...
	if (family is NOT 300, OR
	    family is NOT 350, OR
	    family is NOT V350)
		do another thing;

   this last conditional makes no sense, is always true,
   and obviously was likely meant to be "family is NOT
   300, 350, or V350".  So I've made the code match the
   intent.

fdac4e69a1 sticore: don't activate unsupported GSC STI cards on HPPA
On HPPA there exists some older GSC graphics cards, which need special
graphic-card-BIOS patching to become supported.  Since we don't have yet
implemented the patching, it's better to detect such cards in advance,
inform to the user that there are known problems and to not activate the
card.

Problematic GSC cards and BIOS versions are:
* Hyperdrive/Hyperbowl (A4071A) graphics card series:
   * ID = 0x2BCB015A (Version 8.04/8)
   * ID = 0x2BCB015A (Version 8.04/11)
* Thunder 1 VISUALIZE 48 card:
   * ID = 0x2F23E5FC (Version 8.05/9)
* Thunder 2 VISUALIZE 48 XP card:
   * ID = 0x2F8D570E (Version 8.05/12)
* Some Hyperion and ThunderHawk GSC cards

Further details are described here:

5bb49fcd50 video/fb: cleanup FB_MAJOR usage
Currently, linux/major.h defines a GRAPHDEV_MAJOR (29) that nobody uses,
and linux/fb.h defines the real FB_MAJOR (also 29), that only fbmem.c
needs.  Drop GRAPHDEV_MAJOR from major.h, move FB_MAJOR definition from
fb.h to major.h, and fix fbmem.c to use major.h's definition.

3e074058d7 fbdev: LCD backlight driver using Atmel PWM driver
This patch adds a platform driver using the ATMEL PWM driver to control a
backlight which requires a PWM signal and optional GPIO signal for discrete
on/off signal.  It has been tested on Favr-32 board from EarthLCD.

The driver is configurable by supplying a struct with the platform data.  See
the include/linux/atmel-pwm-bl.h for details.

The board code for Favr-32 will be submitted to the AVR32 kernel list.
