Subject: rtc-ds1307 driver



Hello,

given the recent patch for ds1337 initialization (drivers/i2c/chips),
I would like to ask owners of DS1307, DS1337, DS1338, DS1339, DS1340, ST M41T00
to give a try the rtc-ds1307 driver (drivers/rtc).

I need to be sure that it works (and correctly initializes)
all the chips that claims to support.

Jean would be very happy if we can remove drivers from
i2c/chips ;)

Unless it's broken _recently_ we already have confirmation that rtc-1307
works for DS1307 and M41T00, so it's the other chips that would be most
interesting ...

I think the ds1337.c driver could vanish if we had confirmation that
the ds1307 driver also works on the DS1337 and DS1339 ... so, special
thanks if you can confirm it with those chips. Chip docs say they
are compatible, so far as the driver is concerned.

I don't have access to my ds1337 hardware right now (working away from
my office). Is someone else able to test this?
