+ * formats should be restricted to match the pixel source transmitting mode.
+ *
+ * Example: i.MX8MM SoC integrates the CSI bridge with the Samsung CSIS CSI-2
+ * receiver which operates in dual pixel sampling mode. The CSI bridge should

- Similarly to the legacy control handling, legacy format handling where
formats on the video nodes are influenced by the active format of the
connected subdev should be removed.

-- i.MX7: all of the above, since it uses the imx media core

-- i.MX7: use Frame Interval Monitor

-- imx7-media-csi: Restrict the supported formats list to the SoC version.

- The imx7 CSI bridge can be configured to sample pixel components from the Rx
- queue in single (8bpp) or double (16bpp) component modes. Image format
- variants with different sample sizes (ie YUYV_2X8 vs YUYV_1X16) determine the
- pixel components sampling size per each clock cycle and their packing mode
- (see imx7_csi_configure() for details).
-
- As the imx7 CSI bridge can be interfaced with different IP blocks depending on
- the SoC model it is integrated on, the Rx queue sampling size should match
- the size of the samples transferred by the transmitting IP block.
-
- To avoid mis-configurations of the capture pipeline, the enumeration of the
- supported formats should be restricted to match the pixel source transmitting
- mode.
-
- Example: i.MX8MM SoC integrates the CSI bridge with the Samsung CSIS CSI-2
- receiver which operates in dual pixel sampling mode. The CSI bridge should
- only expose the 1X16 formats variant which instructs it to operate in dual
- pixel sampling mode. When the CSI bridge is instead integrated on an i.MX7,
