Hi Deepanraj,

IMX6 family Linux image provides generic I2C kernel drivers, but there is no specific application driver for this sensor in Linux, this must be developed by the user.

Regards,
Carlos

Unfortunately there are no Linux drivers for this device. In the following document you can find a baremetal driver which you can use as a base to develop your own driver.
