   2 ================================
   3
   4 The driver supports the following options, either via
   5 options=<OPTIONS> when modular or video=pxafb:<OPTIONS> when built in.
   6
   7 For example:
   8         modprobe pxafb options=mode:640x480-8,passive
   9 or on the kernel command line
  10         video=pxafb:mode:640x480-8,passive
  11
  12 mode:XRESxYRES[-BPP]
  13         XRES == LCCR1_PPL + 1
  14         YRES == LLCR2_LPP + 1
  15                 The resolution of the display in pixels
  16         BPP == The bit depth. Valid values are 1, 2, 4, 8 and 16.
  17
  18 pixclock:PIXCLOCK
  19         Pixel clock in picoseconds
  20
  21 left:LEFT == LCCR1_BLW + 1

  23 hsynclen:HSYNC == LCCR1_HSW + 1
  24 upper:UPPER == LCCR2_BFW
  25 lower:LOWER == LCCR2_EFR
  26 vsynclen:VSYNC == LCCR2_VSW + 1
  27         Display margins and sync times
