Studebaker <mdsxyz123@yahoo.com> + +Description +----------- + +The Savage4 chips contain two I2C interfaces (aka a I2C 'master' +or 'host'). + +The first interface is used for DDC (Data Display Channel) which is a +serial channel through the VGA monitor connector to a DDC-compliant +monitor. This interface is defined by the Video Electronics Standards +Association (VESA). The standards are available for purchase at +http://www.vesa.org . The DDC bus is not yet supported because its register +is not directly memory-mapped. + +The second interface is a general-purpose I2C bus. This is the only +interface supported by the driver at the moment. + |
