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

drivers: hierarchize drivers Kconfig menu

2015-08-13T00:47:44+00:00

The menuconfig for drivers are getting more and more cluttered
and unreadable because too many entries are displayed in a single
flat menu.  Use hierarchic menu for each category.

dm: rtc: sandbox: Add a driver for the sandbox I2C RTC

2015-05-06T02:58:40+00:00

Add a driver which communicates with the sandbox I2C emulation RTC device
and permits it to be used in U-Boot. This driver is very simple - it just
reads and writes selected I2C registers in the device.

dm: rtc: sandbox: Add an emulated I2C RTC device

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

Add a sandbox I2C emulation device which emulates a real-time clock. The
clock works off an offset from the current system time, and supports setting
and getting the clock, as well as access to byte-width regisers in the RTC.
It does not support changing the system time.

This device can be used for testing the 'date' command on sandbox, as well
as the RTC uclass.

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: 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.
