I am using latest OpenEmbedded Release on DragonBoard820c(p4).

According to the schematics of DB820cp4, it seems that accel/gyro and magnetometer sensors can either be connected on SSC I2C or BLSP I2C. I believe that resistors on BLSP I2C connections are DNI which means that sensors are connected to SSC I2C. Kindly Confirm the connection?
Incase sensors are connected to SSC, Can you please let us know how can we access them?
