+/*
+ * How to use the V4L2_MBUS_* flags:
+ * Flags are defined for each of the possible states and values of a media
+ * bus configuration parameter. One and only one bit of each group of flags
+ * shall be set by the users of the v4l2_subdev_pad_ops.get_mbus_config and
+ * v4l2_subdev_pad_ops.set_mbus_config operations to ensure that no
+ * conflicting settings are specified when reporting and setting the media bus
+ * configuration with the two operations respectively. For example, it is
+ * invalid to set or clear both the V4L2_MBUS_HSYNC_ACTIVE_HIGH and the
+ * V4L2_MBUS_HSYNC_ACTIVE_LOW flag at the same time. Instead either flag
+ * V4L2_MBUS_HSYNC_ACTIVE_HIGH or flag V4L2_MBUS_HSYNC_ACTIVE_LOW shall be
+ * set. The same is true for the V4L2_MBUS_CSI2_1/2/3/4_LANE flags group: only
+ * one of these four bits shall be set.
+ *
+ * TODO: replace the existing V4L2_MBUS_* flags with structures of fields
+ * to avoid conflicting settings.
+ *
+ * In example:
+ *     #define V4L2_MBUS_HSYNC_ACTIVE_HIGH             BIT(2)
+ *     #define V4L2_MBUS_HSYNC_ACTIVE_LOW              BIT(3)
+ * will be replaced by a field whose value reports the intended active state of
+ * the signal:
+ *     unsigned int v4l2_mbus_hsync_active : 1;
+ */

+/* Parallel flags */
+/*
+ * The client runs in master or in slave mode. By "Master mode" an operation
+ * mode is meant, when the client (e.g., a camera sensor) is producing
+ * horizontal and vertical synchronisation. In "Slave mode" the host is
+ * providing these signals to the slave.
