rtc: fix platform driver hotplug/coldplug

2008-04-11T15:06:44+00:00

Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is
prefixed with "platform:".  Add MODULE_ALIAS() to the hotpluggable RTC
platform drivers, to re-enable module auto loading.

rtc: rtc-sh: Split out the CPU defs to asm/cpu/.

2008-01-28T04:18:58+00:00

With all of the different CPU types this was getting a but unwieldly.
Since sh64 is now integrated, we don't have to worry about multiple
architectures caring about the header definitions.

Split out the defs for each asm/cpu/ to make rtc-sh slightly less
visually offensive.

rtc: rtc-sh: SH-5 support.

2008-01-28T04:18:38+00:00

Trivial support for the SH-5 (sh64) on-chip RTC.

rtc: rtc-sh: Zero out tm value for invalid rtc states.

2007-11-07T11:13:24+00:00

Follows the changes of some of the other RTC drivers. If the tm
value is bogus, just zero it out. Adds some sanity for RTC_RD_TIME.

rtc: sh-rtc: Handle rtc_device_register() failure properly.

2007-11-07T05:58:09+00:00

Currently if rtc_device_register() fails we have an IS_ERR() on
the wrong pointer, which causes this to always be skipped. Fix
this up to actually check the right pointer. The return value
was always correct, even though the check was wrong.

rtc: rtc-sh: Support 4-digit year on SH7705/SH7710/SH7712.

2007-09-21T02:57:47+00:00

All SH-4 parts have a 4-digit year, while the SH-3 parts typically
only use a 2-digit one. The SH7705, SH7710, and SH7712 SH-3 parts
however opted to extend it to 4-digit and still look and act like
an SH-3 RTC in all other ways.

This adds a capability flag (RTC_CAP_4_DIGIT_YEAR) that these
corner-case CPU subtypes can set in their platform data and cleans
up some of the ifdef mess in the driver as a result.

rtc: rtc-sh: Correct sh_rtc_set_time() for some SH-3 parts.

2007-07-26T08:31:28+00:00

Some SH-3 parts (SH7720 and SH7705 at least) need to have the
start bit explicitly cleared, as the reset is not enough. This
is safe across all parts, so simply clear the start bit in
the sh_rtc_set_time() path.

rtc: rtc-sh: Fix rtc_dev pointer for rtc_update_irq().

2007-05-09T03:37:53+00:00

When the rtc_update_irq() callsites stopped passing in the
class_dev, the rtc_dev references weren't fixed. Fix it up,
so we pass in the proper pointer.
