rtc: remove CONFIG_CMD_DATE dependency

2018-07-25T13:00:24+00:00

The EFI subsystem accesses the real time clock and is enabled by default.
So we should drop any CONFIG_CMD_DATE dependency from the real time clock
drivers.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

rtc:ds3232/ds3231: Add support to generate 32KHz output

2015-09-02T02:37:23+00:00

RTC devices can generate 32KHz output if for
-DS3232 device, EN32KHz bit and BB32KHz bit are set
-DS3231 device, EN32KHz bit is set, BB32KHz bit is don't care

Patch adds rtc_enable_32khz_output() which when called
will enable 32KHz output on 32KHz pin

Fix:
ds3231.c: In function 'rtc_get':
ds3231.c:90:52: warning: variable 'control' set but not used
[-Wunused-but-set-variable]

Fix is done by switching to standard debug() instead of custom macro.

LWMON5: POST RTC fix

2008-03-20T20:48:46+00:00

Modify the RTC API to provide one a status for the time reported by
the rtc_get() function:
  0 - a reliable time is guaranteed,
< 0 - a reliable time isn't guaranteed (power fault, clock issues,
      and so on).

The RTC chip drivers are responsible for providing this info if the
corresponding chip supports such functionality. If not - always
report that the time is reliable.

The POST RTC test was modified to detect the RTC faults utilizing
this new rtc_get() feature.
