At present there are only 8-bit and 32-bit read/write routines in
the rtc uclass driver. This adds the 16-bit support.Signed-off-by: Bin Meng

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 carePatch adds rtc_enable_32khz_output() which when called
will enable 32KHz output on 32KHz pinSigned-off-by: Priyanka Jain

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.Signed-off-by: Simon Glass

Move the definition of struct rtc_time into a separate file so that sandbox
can include it without requiring common.h and the like.Signed-off-by: Simon Glass

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.Signed-off-by: Simon Glass

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.Signed-off-by: Simon Glass

Change this function name to something more descriptive. Also return a
failure code if it cannot calculate a correct value.Signed-off-by: Simon Glass

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

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.Signed-off-by: Wolfgang Denk

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.Signed-off-by: Yuri Tikhonov
