Subject: [PATCH 0/7] Generic RTC class driver


        Hi Alessandro et al,

This patch series:
  1. Adds the missing module alias to rtc-parisc (which is a bugfix), and
     performs a few cleanups,
  2. Moves the platform device creation out of rtc-ppc and into arch-specific
     code (which is also a bugfix),
  3. Consolidates rtc-parisc and rtc-ppc into rtc-generic (which is a cleanup),
  4. Hooks up rtc-generic on m68k (it's been using [sg]et_rtc_time() since
     ages),
  5. Makes rtc-generic dependent on PARISC, PPC, and M68K (the existing
     [sg]et_rtc_time() users):
       a. without introducing ARCH_HAS_GENERIC_RTC,
       b. with a big fat warning in the Kconfig comment discouraging people
          from relaxing the dependencies.
  6. Converts the PS3 RTC support into a separate driver, called rtc-ps3
     (as a bonus ;-)

To reduce code churn, the order and number of the actual patches slightly
differs:
  [1] parisc: rtc: get_rtc_time() returns unsigned int
  [2] parisc: rtc: platform_driver_probe() fixups
  [3] parisc: rtc: Add missing module alias
  [4] parisc: rtc: Rename rtc-parisc to rtc-generic
  [5] m68k: Hook up rtc-generic
  [6] powerpc: Hook up rtc-generic, and kill rtc-ppc
  [7] powerpc/ps3: Add rtc-ps3

These patches are relative to the "rtc-parisc" branch of Kyle's PA-RISC git
repository, which already contains some cleanups for the rtc-parisc driver by
Dann, which already have been ack'ed by Alessandro:

http://git.kernel.org/?p=linux/kernel/git/kyle/parisc-2.6.git;a=shortlog;h=rtc-parisc

Paul: Feel free to add your SuperH support.

I suppose the easiest way for this to go in is through Kyle's PA-RISC tree, as
he already has the preceding patches? Can I have your acks, please?

Thanks!
