2 tristate "OMAP frame buffer support (EXPERIMENTAL)"
3 depends on FB && ARCH_OMAP
6 select FB_CFB_IMAGEBLIT
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_LCDC_BLIZZARD
25 bool "Epson Blizzard LCD controller support"
26 depends on FB_OMAP && FB_OMAP_LCDC_EXTERNAL
28 Say Y here if you want to have support for the external
29 Epson Blizzard LCD controller.
31 config FB_OMAP_MANUAL_UPDATE
32 bool "Default to manual update mode"
33 depends on FB_OMAP && FB_OMAP_LCDC_EXTERNAL
35 Say Y here, if your user-space applications are capable of
36 notifying the frame buffer driver when a change has occured in
37 the frame buffer content and thus a reload of the image data to
38 the external frame buffer is required. If unsure, say N.
40 config FB_OMAP_LCD_MIPID
41 bool "MIPI DBI-C/DCS compatible LCD support"
42 depends on FB_OMAP && SPI_MASTER && CBUS_TAHVO
44 Say Y here if you want to have support for LCDs compatible with
45 the Mobile Industry Processor Interface DBI-C/DCS
46 specification. (Supported LCDs: Philips LPH8923, Sharp LS041Y3)
48 config FB_OMAP_BOOTLOADER_INIT
49 bool "Check bootloader initialization"
52 Say Y here if you want to enable checking if the bootloader has
53 already initialized the display controller. In this case the
54 driver will skip the initialization.
56 config FB_OMAP_CONSISTENT_DMA_SIZE
57 int "Consistent DMA memory size (MB)"
62 Increase the DMA consistent memory size according to your video
63 memory needs, for example if you want to use multiple planes.
64 The size must be 2MB aligned.
67 config FB_OMAP_DMA_TUNE
68 bool "Set DMA SDRAM access priority high"
69 depends on FB_OMAP && ARCH_OMAP1
71 On systems in which video memory is in system memory
72 (SDRAM) this will speed up graphics DMA operations.
73 If you have such a system and want to use rotation
74 answer yes. Answer no if you have a dedicated video
75 memory, or don't use any of the accelerated features.
