+ * Here is the rough outline of how we bring up the display:
+ * 1. Upon power-on Sink generates a hot plug detection pulse thru HPD
+ * 2. Source determines video mode by reading DPCD receiver capability field
+ * (DPCD 00000h to 0000Dh) including eDP CP capability register (DPCD
+ * 0000Dh).
+ * 3. Sink replies DPCD receiver capability field.
+ * 4. Source starts EDID read thru I2C-over-AUX.
+ * 5. Sink replies EDID thru I2C-over-AUX.
+ * 6. Source determines link configuration, such as MAX_LINK_RATE and
+ * MAX_LANE_COUNT. Source also determines which type of eDP Authentication
+ * method to use and writes DPCD link configuration field (DPCD 00100h to
+ * 0010Ah) including eDP configuration set (DPCD 0010Ah).
+ * 7. Source starts link training. Sink does clock recovery and equalization.
+ * 8. Source reads DPCD link status field (DPCD 00200h to 0020Bh).
+ * 9. Sink replies DPCD link status field. If main link is not stable, Source
+ * repeats Step 7.
+ * 10. Source sends MSA (Main Stream Attribute) data. Sink extracts video
+ * parameters and recovers stream clock.
+ * 11. Source sends video data.
