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.

db621f174d [PATCH] RTC class: error checks
The rtc_is_valid_tm() routine needs to treat some of the fields it checks as
unsigned, to prevent wrongly accepting invalid rtc_time structs; this is the
same approach used elsewhere in the RTC code for such tests.

Conversely, rtc_proc_show() is missing one invalid-day-of-month test that
rtc_is_valid_tm() makes: there is no day zero.

818a8674b0 [PATCH] RTC class uses subsys_init
This makes RTC core components use "subsys_init" instead of "module_init", as
appropriate for subsystem infrastructure.  This is mostly useful for
statically linking drivers in other parts of the tree that may provide an RTC
interface as a secondary functionality (e.g.  part of a multifunction chip);
they won't need to worry so much about drivers/Makefile link order.

adfb434125 [PATCH] RTC subsystem: fix proc output
Move the "24hr: yes" proc output from drivers to rtc proc code.  This is
required because the time value in the proc output is always in 24hr mode
regardless of the driver.

728a294787 [PATCH] RTC subsystem: proc interface
Add the proc interface to the RTC subsystem.

The first RTC driver which registers with the class will be accessible by
/proc/driver/rtc .

This is required for compatibility with the standard RTC driver and to avoid
breaking any user space application which may erroneusly rely on this.
