Driver for PXA25x LCD controller
================================
The driver supports the following options, either via
options=<OPTIONS> when modular or video=pxafb:<OPTIONS> when built in.
For example:
modprobe pxafb options=mode:640x480-8,passive
or on the kernel command line
video=pxafb:mode:640x480-8,passive
mode:XRESxYRES[-BPP]
XRES == LCCR1_PPL + 1
YRES == LLCR2_LPP + 1
The resolution of the display in pixels
BPP == The bit depth. Valid values are 1, 2, 4, 8 and 16.
pixclock:PIXCLOCK
Pixel clock in picoseconds
left:LEFT == LCCR1_BLW + 1
right:RIGHT == LCCR1_ELW + 1
hsynclen:HSYNC == LCCR1_HSW + 1
upper:UPPER == LCCR2_BFW
lower:LOWER == LCCR2_EFR
vsynclen:VSYNC == LCCR2_VSW + 1
Display margins and sync times
color | mono => LCCR0_CMS
umm...
active | passive => LCCR0_PAS
Active (TFT) or Passive (STN) display
single | dual => LCCR0_SDS
Single or dual panel passive display
4pix | 8pix => LCCR0_DPD
4 or 8 pixel monochrome single panel data
hsync:HSYNC
vsync:VSYNC
Horizontal and vertical sync. 0 => active low, 1 => active
high.
dpc:DPC
Double pixel clock. 1=>true, 0=>false
outputen:POLARITY
Output Enable Polarity. 0 => active low, 1 => active high
pixclockpol:POLARITY
pixel clock polarity
0 => falling edge, 1 => rising edge

depends on ARCH_IXP4XX
help
IXP4xx provides two methods of accessing PCI memory space:
1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).
To access PCI via this space, we simply ioremap() the BAR
into the kernel and we can use the standard read[bwl]/write[bwl]
macros. This is the preffered method due to speed but it
limits the system to just 64MB of PCI memory. This can be
problamatic if using video cards and other memory-heavy devices.
2) If > 64MB of memory space is required, the IXP4xx can be
configured to use indirect registers to access PCI This allows
for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
The disadvantadge of this is that every PCI access requires
three local register accesses plus a spinlock, but in some
cases the performance hit is acceptable. In addition, you cannot
mmap() PCI devices in this case due to the indirect nature
of the PCI window.
By default, the direct method is used. Choose this option if you
need to use the indirect method instead. If you don't know
what you need, leave this option unselected.

Frame buffer driver for the built-in LCD controller in the Intel
PXA2x0 processor.
This driver is also available as a module ( = code which can be
inserted and removed from the running kernel whenever you want). The
module will be called vfb. If you want to compile it as a module,
say M here and read <file:Documentation/modules.txt>.
If unsure, say N.

---help---
Enable the use of kernel command line or module parameters
to configure the physical properties of the LCD panel when
using the PXA LCD driver.
This option allows you to override the panel parameters
supplied by the platform in order to support multiple
different models of flatpanel. If you will only be using a
single model of flatpanel then you can safely leave this
option disabled.
Documentation/fb/pxafb.txt describes the available parameters.

* Suspend
* This refers to a level of power management in which substantial power
* reduction is achieved by the display. The display can have a longer

* Off
* This indicates that the display is consuming the lowest level of power

*
* Now, the fbdev driver adds an additional state, (blank), where they
* turn off the video (maybe by colormap tricks), but don't mess with the
* video itself: think of it semantically between on and Stand-By.
*

* limits the system to just 64MB of PCI memory. This can be
* problamatic if using video cards and other memory-heavy
* targets.
*
* 2) If > 64MB of memory space is required, the IXP4xx can be configured
* to use indirect registers to access PCI (as we do below for I/O
* transactions). This allows for up to 128MB (0x48000000 to 0x4fffffff)
* of memory on the bus. The disadvantadge of this is that every
