    Hi Cesar,

    I really doubt that Linux supports these deserializers in the kernel. I would suggest to refer to existing serializer and deserializer in the kernel and develop driver for them.

    Hi Cesar,

    Currently there is no support for GMSL device on TI Linux SDK.

    You would have to refer the ser-des implementation of the FPD-Link device (UB953 - UB960) and see how it is connected via the device tree and implement the same for the GMSL device.

    You could find the source code in the Linux SDK in the path below

    ${PSDKLA}/board-support/linux-5.10.162+gitAUTOINC+76b3e88d56-g76b3e88d56/drivers/media/i2c/ds90ub960.c - UB960 Deserializer

    ${PSDKLA}/board-support/linux-5.10.162+gitAUTOINC+76b3e88d56-g76b3e88d56/drivers/media/i2c/ds90ub953.c - UB953 Serializer
