Available user-level tool for I2C device?

[Sam Song]

Hi all,

I'd like to ask whether there is user-level utility
for I2C device registers access like lspci/setpci for
PCI device?

I have a RTC chip DS1337 on a 8248 target. It can
work right in u-boot and linux. If no similar utility,
I will switch to change hwclock.c in busybox to make
it. Any idea?

Thanks in advance,

Sam
