Its PCI vendor id is 0x0014, its PCI device id is 0x7a06. In order to let the driver to know which chip the DC is contained in, the compatible of the display controller is named according to the chip's name. For LS7A1000, there are 4 dedicated GPIOs whose control register is located at the DC register space. They are used to emulate i2c for reading edid from the monitor. One for DVO0, another for DVO1. LS2K1000 and LS2K0500 SoC don't have such GPIOs, they grab i2c adapter from other module, either general purpose GPIO emulated i2c or hardware i2c adapter. This patch add common part of the DC device node only, it does not contain ports device note. As it is for the generic, boards only with transparent encoders should works simply by inherit from this.
