3 tristate "OMAP frame buffer support"
5 depends on ARCH_OMAP1 || (ARM && COMPILE_TEST)
6 select FB_IOMEM_HELPERS
8 Frame buffer driver for OMAP based boards.
10 config FB_OMAP_LCDC_EXTERNAL
11 bool "External LCD controller support"
14 Say Y here, if you want to have support for boards with an
15 external LCD controller connected to the SoSSI/RFBI interface.
17 config FB_OMAP_LCDC_HWA742
18 bool "Epson HWA742 LCD controller support"
19 depends on FB_OMAP && FB_OMAP_LCDC_EXTERNAL
21 Say Y here if you want to have support for the external
22 Epson HWA742 LCD controller.
24 config FB_OMAP_MANUAL_UPDATE
25 bool "Default to manual update mode"
26 depends on FB_OMAP && FB_OMAP_LCDC_EXTERNAL
28 Say Y here, if your user-space applications are capable of
29 notifying the frame buffer driver when a change has occurred in
30 the frame buffer content and thus a reload of the image data to
31 the external frame buffer is required. If unsure, say N.
33 config FB_OMAP_LCD_MIPID
34 bool "MIPI DBI-C/DCS compatible LCD support"
35 depends on FB_OMAP && SPI_MASTER
37 Say Y here if you want to have support for LCDs compatible with
38 the Mobile Industry Processor Interface DBI-C/DCS
39 specification. (Supported LCDs: Philips LPH8923, Sharp LS041Y3)
41 config FB_OMAP_DMA_TUNE
42 bool "Set DMA SDRAM access priority high"
45 On systems in which video memory is in system memory
46 (SDRAM) this will speed up graphics DMA operations.
47 If you have such a system and want to use rotation
48 answer yes. Answer no if you have a dedicated video
49 memory, or don't use any of the accelerated features.
