+  MediaTek DP and eDP are different hardwares and there are some features

+  eDP. Therefore, we need to use two different compatibles to describe them.
+  In addition, We just need to enable the power domain of DP, so the clock
+  of DP is generated by itself and we are not using other PLL to generate
+  clocks.
