Developing a new sensor on Jetson nano

Dears,

We are looking to create a sensor driver and device tree on Jetson nano, referring imx219.
While creating the device tree, I’m confused by the I2c slave address setting: according to the datasheet of imx219, the address should be 0b0010000x, “x stands for R/W”, which means it should be 0x21 or 0x20, but looking at the “tegra210-camera-rbpcv2-imx219.dtsi”, it’s setted as 0x10.

Could you kindly help explain, how I can decide the slave address for a Video Input I2C?

Thanks a lot!

For anyone who may have the the same question, the reason is that in Tegra target linux, I2C address should be shift right for one bit.
