rtc: hym8563: in .read_alarm set .tm_sec to 0 to signal minute accuracy

2016-07-19T16:18:06+00:00

Set .tm_sec to 0 instead of -1 to signal minute accuracy.

rtc: simplify implementations of read_alarm

2016-07-09T08:24:45+00:00

Since commit d68778b80dd7 ("rtc: initialize output parameter for read
alarm to "uninitialized"") there is no need to explicitly set
unsupported members to -1. So drop the respective assignments from
drivers.

rtc: hym8563: Remove CLK_IS_ROOT

2016-05-20T10:33:51+00:00

This flag is a no-op now (see commit 47b0eeb3dc8a "clk: Deprecate
CLK_IS_ROOT", 2016-02-02) so remove it.

rtc: hym8563: fix invalid year calculation

2016-03-14T16:08:38+00:00

Year field must be in BCD format, according to
hym8563 datasheet.

Due to the bug year 2016 became 2010.

rtc: Drop owner assignment from i2c_driver

2015-09-05T11:19:06+00:00

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

rtc: hym8563: make the irq optional

2015-06-24T23:13:45+00:00

Sometimes the irq line is not connected to any soc-pin. This does
not hinder basic timekeeping functionality of the rtc, so probe
should not fail in this case.

drivers/rtc/rtc-hym8563.c: fix swapped enable/disable of clockout control bit

2015-04-17T13:04:02+00:00

The hym8563 datasheet describes the clock output control-bit as "when set
to logic 0, the square wave output is enable, when set to logic 1, the
CLKOUT output is inhibited".  But in reality the setting is exactly
opposite.

Before now, the clock output was not really used, but on the rk3288 soc
this generated clock is used to supply the temperature sensor block and
the swapped bit value prevented it from working.  With the corrected
value, the tsadc now reports correct values.

drivers/rtc/rtc-hym8563.c: return clock rate even when clock is disabled

2015-04-17T13:04:01+00:00

When the clock is disabled, do not return a rate of 0 but instead return
the rate the clock will be running at after it gets enabled.  This
prevents problems when the core clock code is trying to determine a
suitable rate, while the clock is still off.

2014-06-06T23:08:08+00:00

This enables the setting of a custom clock name for the clock provided by
the hym8563 rtc.

rtc: rtc-hym8563: make of_device_id array const

Make of_device_id array const, because all OF functions handle it as
const.
