config FB_OMAP tristate "OMAP frame buffer support (EXPERIMENTAL)" depends on FB help Frame buffer driver for OMAP based boards. config FB_OMAP_LCDC_EXTERNAL bool "External LCD controller support" depends on FB_OMAP help Say Y here, if you want to have support for boards with an external LCD controller connected to the SoSSI/RFBI interface. config FB_OMAP_LCDC_HWA742 bool "Epson HWA742 LCD controller support" depends on FB_OMAP && FB_OMAP_LCDC_EXTERNAL help Say Y here if you want to have support for the external Epson HWA742 LCD controller. config FB_OMAP_MANUAL_UPDATE bool "Default to manual update mode" depends on FB_OMAP && FB_OMAP_LCDC_EXTERNAL help Say Y here, if your user-space applications are capable of notifying the frame buffer driver when a change has occured in the frame buffer content and thus a reload of the image data to the external frame buffer is required. If unsure, say N. config FB_OMAP_LCD_MIPID bool "MIPI DBI-C/DCS compatible LCD support" select SPI depends on FB_OMAP help Say Y here if you want to have support for LCDs compatible with the Mobile Industry Processor Interface DBI-C/DCS specification. (Supported LCDs: Philips LPH8923, Sharp LS041Y3) config FB_OMAP_BOOTLOADER_INIT bool "Check bootloader initializaion" depends on FB_OMAP help Say Y here if you want to enable checking if the bootloader has already initialized the display controller. In this case the driver will skip the initialization. config FB_OMAP_CONSISTENT_DMA_SIZE int "Consistent DMA memory size (MB)" depends on FB_OMAP range 1 14 default 2 help Increase the DMA consistent memory size according to your video memory needs, for example if you want to use multiple planes. The size must be 2MB aligned. If unsure say 1. config FB_OMAP_DMA_TUNE bool "Set DMA SDRAM access priority high" depends on FB_OMAP && ARCH_OMAP1 help On systems in which video memory is in system memory (SDRAM) this will speed up graphics DMA operations. If you have such a system and want to use rotation answer yes. Answer no if you have a dedicated video memory, or don't use any of the accelerated features.
