+ * struct dc_crtc - DC specific drm_crtc
+ *
+ * Each display controller contains one content stream and one safety stream.
+ * In general, the two streams have the same functionality. One stream is
+ * overlaid on the other by @fg. This driver chooses to generate black constant
+ * color from the content stream as background color, build plane(s) on the
+ * content stream by using layerblend(s) and always generate a constant color
+ * from the safety stream. Note that due to the decoupled timing, the safety
+ * stream still works to show the constant color properly even when the content
+ * stream has completely hung up due to mal-function of this driver.
