HWMON for tmp123 temperature sensor

Hi,

We have customized zynq board, and have temperature sensor (tmp123) connect to PS through SPI, I enabled "National Semi LM70" from petalinux-config -c kernel. after rebuild, should I see lm70.ko? But I didn't have it also there is no "/sys/class/hwmon/hwmon/temp1_input" file, only I got:

./sys/bus/spi/drivers/lm70

Anybody knows what's going on?
