66AK2G12: LM63 driver sysfs files missing

Part Number: 66AK2G12
Other Parts Discussed in Thread: LM63

Hi,

We are using LM63 as our temperature sensor and fan control chip. There are many sysfs files that the lm63.c driver can export. However, on our system which uses TI 66AK2G12 CPU, only one, temp1_input ,  is availabe:

# ls /sys/class/hwmon/hwmon0/
device@      name         power/       subsystem@   temp1_input  uevent

Other Linux OS can show dozen files. See e2e.ti.com/.../linux-lm63-about-linux-driver-for-lm63

Any idea why? I am wondering if this is the TI's customized Linux OS issue that our system is based upon, ie,

k2g-evm-linux-sdk-src-06.03.00.106/board-support/linux-4.19.94+gitAUTOINC+be5389fd85-gbe5389fd85
