drivers/rtc/rtc-twl.c: use devm_*() functions

2014-01-24T00:36:59+00:00

Use devm_*() functions to make cleanup paths simpler, and remove
unnecessary remove().

drivers/rtc/rtc-twl.c: fix: rtcX/wakealarm attribute isn't created

2013-07-31T21:41:03+00:00

The device_init_wakeup() should be called before rtc_device_register().
Otherwise, sysfs "sys/class/rtc/rtcX/wakealarm" attribute will not be seen
from User space.

drivers/rtc/rtc-twl.c: fix rtc_reg_map initialization

2013-07-03T23:08:00+00:00

Initialize the rtc_reg_map in platform_driver's probe function instead at
module_init time.  This way we can make sure that the twl-core has been
already probed and initialized (twl_priv->twl_id is valid) since the
platform device for the RTC driver will be created by the twl-core after
it finished its init.

drivers/rtc/rtc-twl.c: ensure IRQ is wakeup enabled

2013-07-03T23:07:59+00:00

Currently, the RTC IRQ is never wakeup-enabled so is not capable of
bringing the system out of suspend.

On OMAP platforms, we have gotten by without this because the TWL RTC is
on an I2C-connected chip which is capable of waking up the OMAP via the IO
ring when the OMAP is in low-power states.

However, if the OMAP suspends without hitting the low-power states (and
the IO ring is not enabled), RTC wakeups will not work because the IRQ is
not wakeup enabled.

To fix, ensure the RTC IRQ is wakeup enabled whenever the RTC alarm is
set.

rtc: rtc-twl: remove unnecessary platform_set_drvdata()

2013-07-03T23:07:52+00:00

The driver core clears the driver data to NULL after device_release or
on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata
= NULL when no driver is bound").  Thus, it is not needed to manually
clear the device driver data to NULL.

drivers/rtc/rtc-twl.c: fix missing device_init_wakeup() when booted with device tree

2013-06-12T23:29:45+00:00

When booted in legacy mode device_init_wakeup() gets called by
drivers/mfd/twl-core.c when the children are initialized.  However, when
booted using device tree, the children are created with
of_platform_populate() instead add_children().

This means that the RTC driver will not have device_init_wakeup() set,
and we need to call it from the driver probe like RTC drivers typically
do.

Without this we cannot test PM wake-up events on omaps for cases where
there may not be any physical wake-up event.

rtc: rtc-twl: convert twl4030rtc_driver to dev_pm_ops

Instead of using legacy suspend/resume methods, using newer dev_pm_ops
structure allows better control over power management.

drivers/rtc: use of_match_ptr() macro

2013-02-22T01:22:27+00:00

This eliminates having an #ifdef returning NULL for the case when OF is
disabled.  Maintains consistency in cases where OF is always selected.

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.
