+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:

+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.

+
+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.

-HAYES ESP DRIVER VERSION 2.1
-
-A big thanks to the people at Hayes, especially Alan Adamson. Their support
-has enabled me to provide enhancements to the driver.
-
-Please report your experiences with this driver to me (arobinso@nyx.net). I
-am looking for both positive and negative feedback.
-
-*** IMPORTANT CHANGES FOR 2.1 ***
-Support for PIO mode. Five situations will cause PIO mode to be used:
-1) A multiport card is detected. PIO mode will always be used. (8 port cards
-do not support DMA).
-2) The DMA channel is set to an invalid value (anything other than 1 or 3).
-3) The DMA buffer/channel could not be allocated. The port will revert to PIO
-mode until it is reopened.
-4) Less than a specified number of bytes need to be transferred to/from the
-FIFOs. PIO mode will be used for that transfer only.
-5) A port needs to do a DMA transfer and another port is already using the
-DMA channel. PIO mode will be used for that transfer only.
-
-Since the Hayes ESP seems to conflict with other cards (notably sound cards)
-when using DMA, DMA is turned off by default. To use DMA, it must be turned
-on explicitly, either with the "dma=" option described below or with
-setserial. A multiport card can be forced into DMA mode by using setserial;
-however, most multiport cards don't support DMA.
-
-The latest version of setserial allows the enhanced configuration of the ESP
-card to be viewed and modified.
-***
-
-This package contains the files needed to compile a module to support the Hayes
-ESP card. The drivers are basically a modified version of the serial drivers.
-
-Features:
-
-- Uses the enhanced mode of the ESP card, allowing a wider range of
- interrupts and features than compatibility mode
-- Uses DMA and 16 bit PIO mode to transfer data to and from the ESP's FIFOs,
- reducing CPU load
-- Supports primary and secondary ports
-
-
-If the driver is compiled as a module, the IRQs to use can be specified by
-using the irq= option. The format is:
-
-irq=[0x100],[0x140],[0x180],[0x200],[0x240],[0x280],[0x300],[0x380]
-
-The address in brackets is the base address of the card. The IRQ of
-nonexistent cards can be set to 0. If an IRQ of a card that does exist is set
-to 0, the driver will attempt to guess at the correct IRQ. For example, to set
-the IRQ of the card at address 0x300 to 12, the insmod command would be:
-
-insmod esp irq=0,0,0,0,0,0,12,0
-
-The custom divisor can be set by using the divisor= option. The format is the
-same as for the irq= option. Each divisor value is a series of hex digits,
-with each digit representing the divisor to use for a corresponding port. The
-divisor value is constructed RIGHT TO LEFT. Specifying a nonzero divisor value
-will automatically set the spd_cust flag. To calculate the divisor to use for
-a certain baud rate, divide the port's base baud (generally 921600) by the
-desired rate. For example, to set the divisor of the primary port at 0x300 to
-4 and the divisor of the secondary port at 0x308 to 8, the insmod command would
-be:
-
-insmod esp divisor=0,0,0,0,0,0,0x84,0
-
-The dma= option can be used to set the DMA channel. The channel can be either
-1 or 3. Specifying any other value will force the driver to use PIO mode.
-For example, to set the DMA channel to 3, the insmod command would be:
-
-insmod esp dma=3
-
-The rx_trigger= and tx_trigger= options can be used to set the FIFO trigger
-levels. They specify when the ESP card should send an interrupt. Larger
-values will decrease the number of interrupts; however, a value too high may
-result in data loss. Valid values are 1 through 1023, with 768 being the
-default. For example, to set the receive trigger level to 512 bytes and the
-transmit trigger level to 700 bytes, the insmod command would be:
-
-insmod esp rx_trigger=512 tx_trigger=700
-
-The flow_off= and flow_on= options can be used to set the hardware flow off/
-flow on levels. The flow on level must be lower than the flow off level, and
-the flow off level should be higher than rx_trigger. Valid values are 1
-through 1023, with 1016 being the default flow off level and 944 being the
-default flow on level. For example, to set the flow off level to 1000 bytes
-and the flow on level to 935 bytes, the insmod command would be:
-
-insmod esp flow_off=1000 flow_on=935
-
-The rx_timeout= option can be used to set the receive timeout value. This
-value indicates how long after receiving the last character that the ESP card
-should wait before signalling an interrupt. Valid values are 0 though 255,
-with 128 being the default. A value too high will increase latency, and a
-value too low will cause unnecessary interrupts. For example, to set the
-receive timeout to 255, the insmod command would be:
-
-insmod esp rx_timeout=255
-
-The pio_threshold= option sets the threshold (in number of characters) for
-using PIO mode instead of DMA mode. For example, if this value is 32,
-transfers of 32 bytes or less will always use PIO mode.
-
-insmod esp pio_threshold=32
-
-Multiple options can be listed on the insmod command line by separating each
-option with a space. For example:
-
-insmod esp dma=3 trigger=512
-
-The esp module can be automatically loaded when needed. To cause this to
-happen, add the following lines to /etc/modprobe.conf (replacing the last line
-with options for your configuration):
-
-alias char-major-57 esp
-alias char-major-58 esp
-options esp irq=0,0,0,0,0,0,3,0 divisor=0,0,0,0,0,0,0x4,0
-
-You may also need to run 'depmod -a'.
-
-Devices must be created manually. To create the devices, note the output from
-the module after it is inserted. The output will appear in the location where
-kernel messages usually appear (usually /var/adm/messages). Create two devices
-for each 'tty' mentioned, one with major of 57 and the other with major of 58.
-The minor number should be the same as the tty number reported. The commands
-would be (replace ? with the tty number):
-
-mknod /dev/ttyP? c 57 ?
-mknod /dev/cup? c 58 ?
-
-For example, if the following line appears:
-
-Oct 24 18:17:23 techno kernel: ttyP8 at 0x0140 (irq = 3) is an ESP primary port
-
-...two devices should be created:
-
-mknod /dev/ttyP8 c 57 8
-mknod /dev/cup8 c 58 8
-
-You may need to set the permissions on the devices:
-
-chmod 666 /dev/ttyP*
-chmod 666 /dev/cup*
-
-The ESP module and the serial module should not conflict (they can be used at
-the same time). After the ESP module has been loaded the ports on the ESP card
-will no longer be accessible by the serial driver.
-
-If I/O errors are experienced when accessing the port, check for IRQ and DMA
-conflicts ('cat /proc/interrupts' and 'cat /proc/dma' for a list of IRQs and
-DMAs currently in use).
-
-Enjoy!
