+ * Transcoders contain the timing generators for eDP, DP, and HDMI interfaces.
+ * Intel transcoders are based on Quick Sync Video, which offloads video
+ * encoding and decoding tasks from the CPU to the GPU.
+ *
+ * On Intel silicon, there are four display pipes (DDI-A to DDI-D) that support
+ * blending, color adjustments, scaling, and dithering.
+ *
+ * From the display block diagram perspective, the front end of the display
+ * contains the pipes. The pipes connect to the transcoder. The transcoder
+ * (except for wireless) connects to the DDIs to drive the IO/PHY.
+ *
+ * This logic checks if the DDI-A port is attached to the transcoder and
+ * enabled (bit 27). Traditionally, the on-board display (eDP) is attached to DDI-A.
+ * If the above conditions is met, then the on-board display is present and enabled.
+ *
+ * On platforms without an on-board display (i.e., value at bits 27-30 is between 2-9),
+ * meaning that DDI-A (eDP) is not enabled.
+ *
+ * Additionally, if bits 27-30 are all set to 0, this means that no DDI ports
+ * are enabled, and there is no display.
+ *
+ * Consider external display is present and enabled, if eDP/DDI-A is not enabled
+ * and transcoder is attached to any DDI port (bits 27-30 are not zero).
