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