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=vmem:2M,mode:640x480-8,passive
or on the kernel command line
	video=pxafb:vmem:2M,mode:640x480-8,passive

vmem: VIDEO_MEM_SIZE
	Amount of video memory to allocate (can be suffixed with K or M
	for kilobytes or megabytes)

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
