[PATCH 0/3] watchdog: new driver for STMP3xxx/MX23/MX28

Introduce a new user of the watchdog framework :) This is a rewritten driver
for STMP and imx23/28 (the old one was not compilable anymore due to the
missing mach). Please read the patch descriptions to understand why I think a
rewrite was necessary. The first patch adds an accessor routine to the
RTC-driver which can hopefully go via the watchdog-tree as well. The second
patch adds the new driver, the third removes the old one.

I hope this can make it for 3.3; the old driver was broken (= not compilable)
anyhow, so there cannot be any regression. Tested on a MX28EVK.



Changes since V1:

* don't use EXPORT_SYMBOL for the callback into the RTC anymore.
  Now, the callback is provided via platform_data to make sure it is
  private between RTC and watchdog.

* use more helpers to reduce driver size (module_platform_driver, pm_ops)
