Hello, I would like to get the DS2321 Real time clock to work with lm-sensors. The DS2321 is very similar to the DS1307. In fact the first six bytes are identical. Where the DS1307 has NVRAM, the DS2321 has no ram and instead has a temperature sensor. My current setup is an i.MX21 ARM processor with integrated I2C master/slave controller with appropriate drivers from Freescale connected to the DS2321. From looking at the kernel source with some working I2C peripherals and the source to lm-sensors it seems clear that the 2.4.20 kernel I was given had an older version of lm-sensors integrated into it. My thinking was to take the DS1307 and copy it by hand into the kernel and then modify it as appropriate. So if you could first comment on whether my plan seems sensible I'd be grateful. Second, how is the ds1307 supposed to be accessed? In the documentation for the chip it claims that it works with frodo-nvram and frodo-rtc. What are frodo-nvram and frodo-rtc? Thanks, Ben Sapp.
