045e0e85f2 rtc-ds1307 cleanups
This updates the rtc-ds1307 driver so that converting it to a "new style"
driver (driver model, not legacy i2c model) will involve fewer changes.

 - Use pointer to i2c_client almost everywhere, so that it's easy
   to let the i2c core create that object;

 - Avoid using i2c_client.adapter, since that field is redundant and
   thus may go away (same object as i2c_client.dev.parent).

 - Extend type enum to include various RTCs this is expected to
   work with, and include register support for them.

It also cleans up the support for multiple chip types, and fixes a
glitch that could appear with an un-initialized RTC.

ff8371ac9a [PATCH] constify rtc_class_ops: update drivers
Update RTC framework so that drivers can constify their method tables, moving
them from ".data" to ".rodata".  Then update the drivers.

1abb0dc92d [PATCH] "RTC-framework" driver for DS1307 and similar RTC chips
This is an "RTC-framework" driver for DS1307 and similar RTC chips,

It should be a full replacement for the existing ds1337.c driver (using the
older RTC glue), giving a net increase in the number of RTC chips that work
out-of-the-box.  There's a whole cluster of RTCs that are very similar, but
the 1337 driver was a bit too picky to work with most of them.

Still no support for RTC alarm IRQs (on chips that support them).
