- 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
