+ * enum drm_bus_flags - bus_flags info for &drm_display_info
+ *
+ * This enum defines signal polarities and clock edge information for signals on
+ * a bus as bitmask flags.
+ *
+ * The clock edge information is conveyed by two sets of symbols,
+ * DRM_BUS_FLAGS_*_DRIVE_\* and DRM_BUS_FLAGS_*_SAMPLE_\*. When this enum is
+ * used to describe a bus from the point of view of the transmitter, the
+ * \*_DRIVE_\* flags should be used. When used from the point of view of the
+ * receiver, the \*_SAMPLE_\* flags should be used. The \*_DRIVE_\* and
+ * \*_SAMPLE_\* flags alias each other, with the \*_SAMPLE_POSEDGE and
+ * \*_SAMPLE_NEGEDGE flags being equal to \*_DRIVE_NEGEDGE and \*_DRIVE_POSEDGE
+ * respectively. This simplifies code as signals are usually sampled on the
+ * opposite edge of the driving edge. Transmitters and receivers may however
+ * need to take other signal timings into account to convert between driving
+ * and sample edges.
+ *
+ * @DRM_BUS_FLAG_DE_LOW: The Data Enable signal is active low
+ * @DRM_BUS_FLAG_DE_HIGH: The Data Enable signal is active high
+ * @DRM_BUS_FLAG_PIXDATA_POSEDGE: Legacy value, do not use

+ * the pixel clock
+ * @DRM_BUS_FLAG_PIXDATA_SAMPLE_POSEDGE: Data is sampled on the rising edge of
+ * the pixel clock
+ * @DRM_BUS_FLAG_PIXDATA_SAMPLE_NEGEDGE: Data is sampled on the falling edge of
+ * the pixel clock
+ * @DRM_BUS_FLAG_DATA_MSB_TO_LSB: Data is transmitted MSB to LSB on the bus
+ * @DRM_BUS_FLAG_DATA_LSB_TO_MSB: Data is transmitted LSB to MSB on the bus
