dm: rtc: Add a uclass for real-time clocks

2015-05-06T02:58:39+00:00

Add a uclass for real-time clocks which support getting the current time,
setting it and resetting the chip to a known-working state. Some RTCs have
additional registers which can be used to store settings, so also provide
an interface to these.

dm: rtc: Split structure definition into its own file

2015-05-06T02:58:20+00:00

Move the definition of struct rtc_time into a separate file so that sandbox
can include it without requiring common.h and the like.

dm: rtc: Rename mktime() and reduce the number of parameters

2015-05-06T02:58:20+00:00

Most callers unpack the structure and pass each member. It seems better to
pass the whole structure instead, as with the C library. Also add an rtc_
prefix.

dm: rtc: Rename to_tm() to rtc_to_tm() and add error code

2015-05-06T02:58:20+00:00

Rename this function so that it is clear that it is provided by the RTC.
Also return an error when it cannot function as expected. This is unlikely
to occur since it works for dates since 1752 and many RTCs do not support
such old dates. Still it is better to be accurate.

dm: rtc: Rename gregorian day function

2015-05-06T02:58:20+00:00

Change this function name to something more descriptive. Also return a
failure code if it cannot calculate a correct value.

x86: rtc: mc146818: Add helpers to read/write CMOS RAM

2015-01-24T13:13:44+00:00

On x86 we use CMOS RAM to read and write some settings. Add basic support
for this, including access to registers 128-255.

rtc: remove broken rtc_read and rtc_write declarations

2009-04-01T20:34:37+00:00

commit 04e11cf3 "rtc: add support for 4543 RTC (manufactured by e.g.
EPSON)" introduces the following build error on boards configuring e.g,
the ds1374 rtc:

Configuring for MPC837XEMDS board...
ds1374.c:103: error: static declaration of 'rtc_read' follows non-static declaration
/home/r1aaha/git/u-boot/include/rtc.h:64: error: previous declaration of 'rtc_read' was here
ds1374.c:104: error: conflicting types for 'rtc_write'
/home/r1aaha/git/u-boot/include/rtc.h:65: error: previous declaration of 'rtc_write' was here

this reverts the erroneous chunk.
