rtc: rtc-r9701: use spi_set_drvdata()

2013-04-30T01:28:34+00:00

Use the wrapper functions for getting and setting the driver data using
spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we
can directly pass a struct spi_device.

rtc: rtc-r9701: use devm_rtc_device_register()

2013-04-30T01:28:31+00:00

devm_rtc_device_register() is device managed and makes cleanup paths
simpler.

Drivers: rtc: remove __dev* attributes.

2013-01-03T23:57:02+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

drivers/rtc/rtc-r9701.c: check that r9701_set_datetime() succeeded

2012-07-31T00:25:18+00:00

When the driver detects that the clock time is invalid, it attempts to
write a sane time into the hardware.  We curently assume that everything
is OK if those writes succeeded.  But it is better to re-read the time
from the hardware to ensure that the new settings got there OK.

drivers/rtc/rtc-r9701.c: avoid second call to rtc_valid_tm()

2012-07-31T00:25:18+00:00

r9701_get_datetime() calls rtc_valid_tm() and returns the value returned
by rtc_valid_tm(), which can be used in the `if', so calling
rtc_valid_tm() a second time is not required.

drivers/rtc/rtc-r9701.c: reset registers if invalid values are detected

2012-04-12T20:12:12+00:00

hwclock refuses to set date/time if RTC registers contain invalid
values.  Check the date/time register values at probe time and
initialize them to make hwclock happy.

rtc: convert rtc spi drivers to module_spi_driver

drivers/rtc/rtc-r9701.c: fix crash in r9701_remove()

2012-03-05T23:49:43+00:00

If probing the RTC didn't succeed due to failed RTC register access, the
RTC device will be unregistered.  Then, when removing the module
r9701_remove() causes a kernel crash while trying to unregister a not
registered RTC device.  Fix this by doing RTC register access test before
RTC device registration.

spi: prefix modalias with "spi:"

2009-09-23T14:39:43+00:00

This makes it consistent with other buses (platform, i2c, vio, ...).  I'm
not sure why we use the prefixes, but there must be a reason.

This was easy enough to do it, and I did it.
