2 tristate "One Laptop Per Child Display CONtroller support"
5 depends on BACKLIGHT_LCD_SUPPORT
6 depends on (GPIO_CS5535 || GPIO_CS5535=n)
7 select BACKLIGHT_CLASS_DEVICE
9 In order to support very low power operation, the XO laptop uses a
10 secondary Display CONtroller, or DCON. This secondary controller
11 is present in the video pipeline between the primary display
12 controller (integrate into the processor or chipset) and the LCD
13 panel. It allows the main processor/display controller to be
14 completely powered off while still retaining an image on the display.
15 This controller is only available on OLPC platforms. Unless you have
16 one of these platforms, you will want to say 'N'.
19 bool "OLPC XO-1 DCON support"
20 depends on FB_OLPC_DCON && GPIO_CS5535
23 Enable support for the DCON in XO-1 model laptops. The kernel
24 communicates with the DCON using model-specific code. If you
25 have an XO-1 (or if you're unsure what model you have), you should
28 config FB_OLPC_DCON_1_5
29 bool "OLPC XO-1.5 DCON support"
30 depends on FB_OLPC_DCON && ACPI
33 Enable support for the DCON in XO-1.5 model laptops. The kernel
34 communicates with the DCON using model-specific code. If you
35 have an XO-1.5 (or if you're unsure what model you have), you
