Subsystem -+------------------------- -+ -+This is an almost total rewrite of the OMAP FB driver in drivers/video/omap -+(let's call it DSS1). The main differences between DSS1 and DSS2 are DSI, -+TV-out and multiple display support, but there are lots of small improvements -+also. -+ -+The DSS2 driver (omapdss module) is in arch/arm/plat-omap/dss/, and the FB, -+panel and controller drivers are in drivers/video/omap2/. DSS1 and DSS2 live -+currently side by side, you can choose which one to use. -+ -+Features -+-------- -+ -+Working and tested features include: -+ -+- MIPI DPI (parallel) output -+- MIPI DSI output in command mode -+- MIPI DBI (RFBI) output -+- SDI output -+- TV output -+- All pieces can be compiled as a module or inside kernel -+- Use DISPC to update any of the outputs -+- Use CPU to update RFBI or DSI output -+- OMAP DISPC planes -+- RGB16, RGB24 packed, RGB24 unpacked -+- YUV2, UYVY -+- Scaling -+- Adjusting DSS FCK to find a good pixel clock -+- Use DSI DPLL to create DSS FCK -+ -+Tested boards include: -+- OMAP3 SDP board -+- Beagle board -+- N810 -+ -+omapdss driver -+-------------- -+ -+The DSS driver does not itself have any support for Linux framebuffer, V4L or -+such like the current ones, but it has an internal kernel API that upper level -+drivers can use. -+ -+The DSS driver models OMAP's overlays, overlay managers and displays in a -+flexible way to enable non-common multi-display configuration. In addition to -+modelling the hardware overlays, omapdss supports virtual overlays and overlay -+managers. These can be used when updating a display with CPU or system DMA. -+ -+Panel and controller drivers -+---------------------------- -+ -+The drivers implement panel or controller specific functionality and are not -+usually visible to users except through omapfb driver. They register -+themselves to the DSS driver. -+ -+omapfb driver -+------------- -+ -+The omapfb driver implements arbitrary number of standard linux framebuffers. -+These framebuffers can be routed flexibly to any overlays, thus allowing very -+dynamic display architecture. -+ -+The driver exports some omapfb specific ioctls, which are compatible with the -+ioctls in the old driver. -+ -+The rest of the non standard features are exported via sysfs. Whether the final -+implementation will use sysfs, or ioctls, is still open. -+ -+V4L2 drivers -+------------ -+ -+V4L2 is being implemented in TI. -+ -+From omapdss point of view the V4L2 drivers should be similar to framebuffer -+driver. -+ -+Architecture -+-------------------- -+ -+Some clarification what the different components do: -+ -+ - Framebuffer is a memory area inside OMAP's SRAM/SDRAM that contains the -+ pixel data for the image. Framebuffer has width and height and color -+ depth. -+ - Overlay defines where the pixels are read from and where they go on the -+ screen. The overlay may be smaller than framebuffer, thus displaying only -+ part of the framebuffer. The position of the overlay may be changed if -+ the overlay is smaller than the display. -+ - Overlay manager combines the overlays in to one image and feeds them to -+ display. -+ - Display is the actual physical display device. -+ -+A framebuffer can be connected to multiple overlays to show the same pixel data -+on all of the overlays. Note that in this case the overlay input sizes must be -+the same, but, in case of video overlays, the output size can be different. Any -+framebuffer can be connected to any overlay. -+ -+An overlay can be connected to one overlay manager. Also DISPC overlays can be -+connected only to DISPC overlay managers, and virtual overlays can be only -+connected to virtual overlays. -+ -+An overlay manager can be connected to one display. There are certain -+restrictions which kinds of displays an overlay manager can be connected: -+ -+ - DISPC TV overlay manager can be only connected to TV display. -+ - Virtual overlay managers can only be connected to DBI or DSI displays. -+ - DISPC LCD overlay manager can be connected to all displays, except TV -+ display. -+ -+Sysfs -+----- -+The sysfs interface is mainly used for testing.
