Subject: [PATCH 00/10] [RFC] RTC: Cleanups for 2.6.39

I believe all the RTC regressions in 2.6.38 are addressed,
so I wanted  to send these changes out for comment before
I push them to Thomas and the -tip tree for testing and
hopeful inclusion into 2.6.39.

Now that the generic RTC layer is virtualizing the various
legacy irq modes, and managing the hardware itself instead
of exposing the hardware functions directly to userland, it 
greatly simplifies what is required from an RTC driver.

No longer do we use the irq_set_state, irq_set_freq,
update_irq_enable and read_alarm function in the hardware
specific RTC drivers. So that code can be removed.

This really does take a buzzsaw to the code, so I want to
make sure there really are no objections to removing it
before we do so.

There may also be some further driver specific cleanups
needed. For example, included in this set are Marcelo's
changes to the sa1100 rtc driver to further reduce the
amount of driver level code.

Let me know what you think.

thanks
-john
