I started to add some pr_debug()s. It seems that rtc-ds1307's ds1307_init()
is just never called despite the module gets loaded.
Hello Clemens,
Do you have rtc node in your dts file (I'm assuming arch/powerpc
situation)? If not, you'll have to add it - for example similarly to
what's being done in the attached patch (68 is the I2C address of the
RTC chip - a DS1339 in my case).
HTH,
