| sa1100fb - SA-1100 LCD graphic framebuffer driver | |
| ================================================= | |
| This is a driver for a graphic framebuffer for the SA-1100 LCD | |
| controller. | |
| Configuration | |
| ============== | |
| For most common passive displays, giving the option:: | |
| video=sa1100fb:bpp:<value>,lccr0:<value>,lccr1:<value>,lccr2:<value>,lccr3:<value> | |
| on the kernel command line should be enough to configure the | |
| controller. The bits per pixel (bpp) value should be 4, 8, 12, or | |
| 16. LCCR values are display-specific and should be computed as | |
| documented in the SA-1100 Developer's Manual, Section 11.7. Dual-panel | |
| displays are supported as long as the SDS bit is set in LCCR0; GPIO<9:2> | |
| are used for the lower panel. | |
| For active displays or displays requiring additional configuration | |
| (controlling backlights, powering on the LCD, etc.), the command line | |
| options may not be enough to configure the display. Adding sections to | |
| sa1100fb_init_fbinfo(), sa1100fb_activate_var(), | |
| sa1100fb_disable_lcd_controller(), and sa1100fb_enable_lcd_controller() | |
| will probably be necessary. | |
| Accepted options:: | |
| bpp:<value> Configure for <value> bits per pixel | |
| lccr0:<value> Configure LCD control register 0 (11.7.3) | |
| lccr1:<value> Configure LCD control register 1 (11.7.4) | |
| lccr2:<value> Configure LCD control register 2 (11.7.5) | |
| lccr3:<value> Configure LCD control register 3 (11.7.6) | |
