-  This file describes how to add DDC support to a chipset driver.
-
-1) DDC INITIALIZATION
-
-   When implementing DDC in the driver one has the choice between
-   DDC1 and DDC2. 
-   DDC1 data is continuously transmitted by a DDC1 capable display 
-   device. The data is send serially over a data line; the Vsync 
-   signal serves as clock. Only one EDID 1.x data block can be 
-   transmitted using DDC1. Since transmission of an EDID1 block 
-   using a regular Vsync frequency would take up several seconds 
-   the driver can increase the Vsync frequency to up to 25 kHz as 
-   soon as it detects DDC1 activity on the data line.
-   DDC2 data is transmitted using the I2C protocol. This requires
-   an additional clock line. DDC2 is capable of transmitting EDID1
-   and EDID2 block as well as a VDIF block on display devices that 
-   support these.  
-   Display devices switch into the DDC2 mode as soon as they detect
-   activity on the DDC clock line. Once the are in DDC2 mode they
-   stop transmitting DDC1 signals until the next power cycle.
-
-   Some graphics chipset configurations which are not capable of
-   DDC2 might still be able to read DDC1 data. Where available
-   DDC2 it is preferable. 
-	
-   All relevant prototypes and defines are in xf86DDC.h.
-   DDC2 additionally requires I2C support. The I2C prototypes
-   are in xf86i2c.h.
-
-   DDC1 Support:
-
-     The driver has to provide a read function which waits for the
-     end of the next Vsync signal and reads in and returns the status
-     of the DDC line:
-
-     unsigned int XXX_ddc1Read(ScrnInfoPtr pScrn)
-     
-     Additionally a function is required to increase the Vsync
-     frequency to max. 25 kHz. 
- 
-     void XXX_ddc1SetSpeed(ScrnInfoPtr pScrn, xf86ddcSpeed speed)
- 
-     If the speed argument is DDC_FAST the function should increase
-     the Vsync frequency on DDC_SLOW it should restore the original
-     value. For convenience a generic ddc1SetSpeed() function is provided
-     in the vga module for VGA-like chipsets.     
-	
-     void vgaHWddc1SetSpeed(ScrnInfoPtr pScrn, sf86ddcSpeed speed).
-

-                              unsigned int (*DDC1Read)(ScrnInfoPtr))
- 
-     in PreInit(). DDC1SetSpeed is a pointer to the SetSpeed()

+   DDC1 data is continuously transmitted by a DDC1 capable display 

+   device. The data is send serially over a data line; the Vsync 

+   signal serves as clock. Only one EDID 1.x data block can be 

+   transmitted using DDC1. Since transmission of an EDID1 block 

+   using a regular Vsync frequency would take up several seconds 

+   the driver can increase the Vsync frequency to up to 25 kHz as 

+   soon as it detects DDC1 activity on the data line.

+   DDC2 data is transmitted using the I2C protocol. This requires

+   an additional clock line. DDC2 is capable of transmitting EDID1

+   and EDID2 block as well as a VDIF block on display devices that 

+   support these.  

+   Display devices switch into the DDC2 mode as soon as they detect

+   activity on the DDC clock line. Once the are in DDC2 mode they

+   stop transmitting DDC1 signals until the next power cycle.

+

+   Some graphics chipset configurations which are not capable of

+   DDC2 might still be able to read DDC1 data. Where available

+   DDC2 it is preferable. 

+	

+   All relevant prototypes and defines are in xf86DDC.h.

+   DDC2 additionally requires I2C support. The I2C prototypes

+   are in xf86i2c.h.

+

+   DDC1 Support:

+

+     The driver has to provide a read function which waits for the

+     end of the next Vsync signal and reads in and returns the status

+     of the DDC line:

+     unsigned int XXX_ddc1Read(ScrnInfoPtr pScrn)

+     the Vsync frequency on DDC_SLOW it should restore the original

+     value. For convenience a generic ddc1SetSpeed() function is provided

+     in the vga module for VGA-like chipsets.

+                              void (*DDC1SetSpeed)(ScrnInfoPtr, xf86ddcSpeed),

+                              unsigned int (*DDC1Read)(ScrnInfoPtr))

+

+   DDC2 Support

+ 

+     To read out DDC2 information I2C has to be initialized first.

+     (See documentation for the i2c module). 

+     The function 

+     

+     xf86MonPtr xf86DoEDID_DDC2(int scrnIndex, I2CBusPtr pBus)

+

+     is provided to read out and process DDC2 data. A pointer

+     to the I2CBusRec of the appropriate I2C Bus has to be passed

+     as the second argument.

+     The function will return a pointer to the xf86Monitor structure

+     which contains all information retrieved by DDC.

+

+   Printing monitor parameters   

+

+     To print out the information contained in the xf86Monitor

+     structure the function 

+

+     xf86MonPtr xf86PrintEDID(xf86MonPtr monitor)

+ 

+     is provided.

+    implemented. However, it is planned to use the information
