    Hi,

    It seems the answer is yes:

    $ git grep -i MT9M114
drivers/staging/media/atomisp/i2c/Kconfig:config VIDEO_ATOMISP_MT9M114
drivers/staging/media/atomisp/i2c/Kconfig:      tristate "Aptina mt9m114 sensor support"
drivers/staging/media/atomisp/i2c/Kconfig:        mt9m114 1.3 Mpixel camera.
drivers/staging/media/atomisp/i2c/Kconfig:        mt9m114 is video camera sensor.
drivers/staging/media/atomisp/i2c/Makefile:obj-$(CONFIG_VIDEO_ATOMISP_MT9M114)    += atomisp-mt9m114.o

    Please note this driver exists in kernel v5.10.y, not v5.4.y.

    The driver is seen in SDK, and believed it's an x86 and not ARM.
    If you try to build the kernel for ARM this driver does not appear.

    Hi,

    I think you are correct, this driver depends on ACPI which is not supported in ARM architecture, so the driver won't be enabled for AM437x.

     40 config VIDEO_ATOMISP_MT9M114                                                    
 41         tristate "Aptina mt9m114 sensor support"                                
 42         depends on ACPI                                                         
 43         depends on I2C && VIDEO_V4L2                                            
 44         help                                                                    
 45           This is a Video4Linux2 sensor-level driver for the Micron
