This patch adds sh_mobile_lcdcfb deferred io support for SYS panels.
The LCDC hardware block managed by the sh_mobile_lcdcfb driver supports
RGB or SYS panel configurations. SYS panels come with an external display
controller that is resposible for refreshing the actual LCD panel. RGB
panels are controlled directly by the LCDC and they need to be refreshed
by the LCDC hardware.In the case of SYS panels we can save some power by configuring the LCDC
hardware block in one-shot mode. In this one-shot mode panel refresh is
managed by software. This works well together with deferred io since it
allows us to stop clocks for most of the time and only enable clocks when
we actually want to trigger an update. When there is no fbdev activity
the clocks are kept stopped which allows us to deep sleep.The refresh rate in deferred io mode is set using platform data. The same
platform data can also be used to disable deferred io mode.As with other deferred io frame buffers user space code should use fsync()
on the frame buffer device to trigger an update.Signed-off-by: Magnus Damm

Implement support for HW color expansion of 1bpp images, along with some
improvements to the FIFO handling and other accel operations.The offset fixup code is now unnecessary as the fbcon core will call our
set_par upon switch back from KD_GRAPHICS before anything else happens. I
removed it as it would slow down accel operations.The fifo wait has been improved to avoid hitting the HW register as often,
and the various accel ops are now performing better caching of register
values.Overall, this improve accel performances. The imageblit acceleration does
result in a small overall regression in performances on some machines (on
the order of 5% on some x86), probably becaus the SW path provides a
better bus utilisation, but I decided to ingnore that as the performances
is still very good, and on the other hand, some machines such as some
sparc64 get a 3 fold performance improvement.Signed-off-by: Benjamin Herrenschmidt

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[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.Signed-off-by: David S. Miller

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.Signed-off-by: David S. Miller

by software (See application note AT91SAM9 LCD Controller

On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from
the LCD controller. It's controlled by "contrast" registers though.This patch lets boards declare that they have that kind of backlight
control. The driver can then export this control, letting screenblank and
other operations actually take effect ... reducing the typically
substantial power drain from the backlight.Note that it's not fully cooked
- doesn't force backlight off during system suspend
- the "power" and "blank" events may not be done right
This should be easily added in the future.[nicolas.ferre@atmel.com: remove unneeded inline and rename functions]
