• Wait for MIPI D-PHY to receive the sensor clock and data until clock and data are
stable by calling mipi_csi2_dphy_status() and mipi_csi2_get_error1().
• When uninstalling the sensor driver, disable the MIPI CSI2 interface by calling
mipi_csi2_disable().
For sample code that explains how the MIPI sensor uses MIPI APIs, refer to the
OV5640_mipi driver source code.
For the IPU CSI module driver, the call steps are as follows:
• Get the MIPI information by calling mipi_csi2_get_info().
• Get the IPU ID and CSI ID to assure configuration of the correct CSI module by
calling mipi_csi2_get_bind_ipu() and mipi_csi2_get_bind_csi().
• Get the data type and virtual channel from MIPI CSI2 driver and configure the CSI
module by calling mipi_csi2_get_datatype() and mipi_csi2_get_virtual_channel().
• Perform other configuration operations for the CSI module and enable CSI.
• Enable the pixel clock to transfer data from MIPI D-PHY to IPU CSI by calling
mipi_csi2_pixelclk_enable().
• When all tasks are done, disable the CSI module first,and then disable the MIPI pixel
clock by calling mipi_csi2_pixelclk_disable().
For sample code that explains how CSI module driver uses MIPI APIs, refer to the IPU
CSI module driver source code.
