-+OMAP2/3 Display 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. I don't think sysfs
-+interface is the best for this in the final version, but I don't quite know
-+what would be the best interfaces for these things.
-+
-+The sysfs interface is divided to two parts: DSS and FB.
-+
-+/sys/class/graphics/fb? directory:
-+mirror 0=off, 1=on
-+rotate Rotation 0-3 for 0, 90, 180, 270 degrees
-+rotate_type 0 = DMA rotation, 1 = VRFB rotation
-+overlays List of overlay numbers to which framebuffer pixels go
-+phys_addr Physical address of the framebuffer
-+virt_addr Virtual address of the framebuffer
-+size Size of the framebuffer
-+
-+/sys/devices/platform/omapdss/overlay? directory:
-+enabled 0=off, 1=on
-+input_size width,height (ie. the framebuffer size)
-+manager Destination overlay manager name
-+name
-+output_size width,height
-+position x,y
-+screen_width width
-+global_alpha global alpha 0-255 0=transparent 255=opaque
-+
-+/sys/devices/platform/omapdss/manager? directory:
-+display Destination display
-+name
-+alpha_blending_enabled 0=off, 1=on
-+trans_key_enabled 0=off, 1=on
-+trans_key_type gfx-destination, video-source
-+trans_key_value transparency color key (RGB24)
-+default_color default background color (RGB24)
-+
-+/sys/devices/platform/omapdss/display? directory:
-+ctrl_name Controller name
-+mirror 0=off, 1=on
-+update_mode 0=off, 1=auto, 2=manual
-+enabled 0=off, 1=on
-+name
-+rotate Rotation 0-3 for 0, 90, 180, 270 degrees
-+timings Display timings (pixclock,xres/hfp/hbp/hsw,yres/vfp/vbp/vsw)
-+ When writing, two special timings are accepted for tv-out:
-+ "pal" and "ntsc"
-+panel_name
-+tear_elim Tearing elimination 0=off, 1=on
-+
-+There are also some debugfs files at <debugfs>/omapdss/ which show information
-+about clocks and registers.
-+
-+Examples
-+--------
-+
-+The following definitions have been made for the examples below:
-+
-+ovl0=/sys/devices/platform/omapdss/overlay0
-+ovl1=/sys/devices/platform/omapdss/overlay1
-+ovl2=/sys/devices/platform/omapdss/overlay2
-+
-+mgr0=/sys/devices/platform/omapdss/manager0
-+mgr1=/sys/devices/platform/omapdss/manager1
-+
-+lcd=/sys/devices/platform/omapdss/display0
-+dvi=/sys/devices/platform/omapdss/display1
-+tv=/sys/devices/platform/omapdss/display2
-+
-+fb0=/sys/class/graphics/fb0
-+fb1=/sys/class/graphics/fb1
-+fb2=/sys/class/graphics/fb2
-+
-+Default setup on OMAP3 SDP
-+--------------------------
-+
-+Here's the default setup on OMAP3 SDP board. All planes go to LCD. DVI
-+and TV-out are not in use. The columns from left to right are:
-+framebuffers, overlays, overlay managers, displays. Framebuffers are
-+handled by omapfb, and the rest by the DSS.
-+
-+FB0 --- GFX -\ DVI
-+FB1 --- VID1 --+- LCD ---- LCD
-+FB2 --- VID2 -/ TV ----- TV
-+
-+Example: Switch from LCD to DVI
-+----------------------
-+
-+w=`cat $dvi/timings | cut -d "," -f 2 | cut -d "/" -f 1`
-+h=`cat $dvi/timings | cut -d "," -f 3 | cut -d "/" -f 1`
-+
-+echo "0" > $lcd/enabled
-+echo "" > $mgr0/display
-+fbset -fb /dev/fb0 -xres $w -yres $h -vxres $w -vyres $h
-+# at this point you have to switch the dvi/lcd dip-switch from the omap board
-+echo "dvi" > $mgr0/display
-+echo "1" > $dvi/enabled
-+
-+After this the configuration looks like:
-+
-+FB0 --- GFX -\ -- DVI
-+FB1 --- VID1 --+- LCD -/ LCD
-+FB2 --- VID2 -/ TV ----- TV
-+
-+Example: Clone GFX overlay to LCD and TV
-+-------------------------------
-+
-+w=`cat $tv/timings | cut -d "," -f 2 | cut -d "/" -f 1`
-+h=`cat $tv/timings | cut -d "," -f 3 | cut -d "/" -f 1`
-+
-+echo "0" > $ovl0/enabled
-+echo "0" > $ovl1/enabled
-+
-+echo "" > $fb1/overlays
-+echo "0,1" > $fb0/overlays
-+
-+echo "$w,$h" > $ovl1/output_size
-+echo "tv" > $ovl1/manager
-+
-+echo "1" > $ovl0/enabled
-+echo "1" > $ovl1/enabled
-+
-+echo "1" > $tv/enabled
-+
-+After this the configuration looks like (only relevant parts shown):
-+
-+FB0 +-- GFX ---- LCD ---- LCD
-+ \- VID1 ---- TV ---- TV
-+
-+Misc notes
-+----------
-+
-+OMAP FB allocates the framebuffer memory using the OMAP VRAM allocator.
-+
-+Using DSI DPLL to generate pixel clock it is possible produce the pixel clock
-+of 86.5MHz (max possible), and with that you get 1280x1024@57 output from DVI.
-+
-+Rotation and mirroring currently only supports RGB565 and RGB8888 modes. VRFB
-+does not support mirroring.
-+
-+VRFB rotation requires much more memory than non-rotated framebuffer, so you
-+probably need to increase your vram setting before using VRFB rotation. Also,
-+many applications may not work with VRFB if they do not pay attention to all
-+framebuffer parameters.
-+
-+Kernel boot arguments
-+---------------------
-+
-+vram=<size>
-+ - Amount of total VRAM to preallocate. For example, "10M". omapfb
-+ allocates memory for framebuffers from VRAM.
-+
-+omapfb.mode=<display>:<mode>[,...]
-+ - Default video mode for specified displays. For example,
-+ "dvi:800x400MR-24@60". See drivers/video/modedb.c.
-+ There are also two special modes: "pal" and "ntsc" that
-+ can be used to tv out.
-+
-+omapfb.vram=<fbnum>:<size>[@<physaddr>][,...]
-+ - VRAM allocated for a framebuffer. Normally omapfb allocates vram
-+ depending on the display size. With this you can manually allocate
-+ more or define the physical address of each framebuffer. For example,
-+ "1:4M" to allocate 4M for fb1.
-+
-+omapfb.debug=<y|n>
-+ - Enable debug printing. You have to have OMAPFB debug support enabled
-+ in kernel config.
-+
-+omapfb.test=<y|n>
-+ - Draw test pattern to framebuffer whenever framebuffer settings change.
-+ You need to have OMAPFB debug support enabled in kernel config.
-+
-+omapfb.vrfb=<y|n>
-+ - Use VRFB rotation for all framebuffers.
-+
-+omapfb.rotate=<angle>
-+ - Default rotation applied to all framebuffers.
-+ 0 - 0 degree rotation
-+ 1 - 90 degree rotation
-+ 2 - 180 degree rotation
-+ 3 - 270 degree rotation
-+
-+omapfb.mirror=<y|n>
-+ - Default mirror for all framebuffers. Only works with DMA rotation.
-+
-+omapdss.def_disp=<display>
-+ - Name of default display, to which all overlays will be connected.
-+ Common examples are "lcd" or "tv".
-+
-+omapdss.debug=<y|n>
-+ - Enable debug printing. You have to have DSS debug support enabled in
-+ kernel config.
-+
-+TODO
-+----
-+
-+DSS locking
-+
-+Error checking
-+- Lots of checks are missing or implemented just as BUG()
-+
-+System DMA update for DSI
-+- Can be used for RGB16 and RGB24P modes. Probably not for RGB24U (how
-+ to skip the empty byte?)
-+
-+OMAP1 support
-+- Not sure if needed
-+

-+ help
-+ This can be used to adjust the minimum FCK/PCK ratio.
-+
-+ With this you can make sure that DISPC FCK is at least
-+ n x PCK. Video plane scaling requires higher FCK than
-+ normally.
-+
-+ If this is set to 0, there's no extra constraint on the
-+ DISPC FCK. However, the FCK will at minimum be
-+ 2xPCK (if active matrix) or 3xPCK (if passive matrix).
-+
-+ Max FCK is 173MHz, so this doesn't work if your PCK
-+ is very high.
