PROCESSOR-SDK-AM437X: I2C device not detected

Part Number: PROCESSOR-SDK-AM437X
Other Parts Discussed in Thread: HDC1080

HDC1080 is not detected after port to sdk 6.0. My recollection is that I only needed to load the driver in the .config and add part to dts.  

After porting these changes i see:

./firmware/devicetree/base/ocp@44000000/i2c@44e0b000/hdc100x@40

and I see:

./modules/4.19.38-g4dae378bbe/kernel/drivers/iio/humidity/hdc100x.ko

I do not see an entry like:

/sys/bus/i2c/devices/0-0040/iio:device0#

Am I forgetting something obvious?  Any advice to debug?
