Hi All,

Hi Christian,

As for your driver support, it would indeed be a good idea to
get it supported in the upstream kernel. You should post a
new mail about that. Take a look at these 3 commits:

61f7162117d4767875825abf2f6ed1eeebbcceed
9cd55be4d22376893d2818ce3c0e5706a3d74121
ca99140a63b7326ee9a38f64c326317f2c63b594

Your patch comes from code based on the second one. The last
commit removed it, and says that it is not the best way to
implement it. You could cc this list and some of the people
involved with those commits and ask ask for advice about
getting your driver supported.

Actually, it's almost supported by the base PASemi code anyway, there is a
PCMCIA driver in setup.c, but our hardware has been changed enough to make it
hang the system when used. I should probably take another look and see If I
can fix that. The other option would be to move the above patch to where we
add our rtc platform device. One thing that does confuse me is the interrupt,
it's attached to GPIO 0, so should be on the mpic int 0 (or maybe 16?)but I
could never get it to work.
