1 Driver for PXA25x LCD controller
2 ================================
4 The driver supports the following options, either via
5 options=<OPTIONS> when modular or video=pxafb:<OPTIONS> when built in.
8 modprobe pxafb options=vmem:2M,mode:640x480-8,passive
9 or on the kernel command line
10 video=pxafb:vmem:2M,mode:640x480-8,passive
13 Amount of video memory to allocate (can be suffixed with K or M
14 for kilobytes or megabytes)
19 The resolution of the display in pixels
20 BPP == The bit depth. Valid values are 1, 2, 4, 8 and 16.
23 Pixel clock in picoseconds
25 left:LEFT == LCCR1_BLW + 1
26 right:RIGHT == LCCR1_ELW + 1
27 hsynclen:HSYNC == LCCR1_HSW + 1
28 upper:UPPER == LCCR2_BFW
29 lower:LOWER == LCCR2_EFR
30 vsynclen:VSYNC == LCCR2_VSW + 1
31 Display margins and sync times
