rtc: rtc-jz4740: use devm_ioremap_resource()

2014-04-03T23:21:19+00:00

Use devm_ioremap_resource() in order to make the code simpler, and move
'struct resource *mem' from 'struct jz4740_rtc' to jz4740_rtc_probe()
because the 'mem' variable is used only in jz4740_rtc_probe().  Also the
redundant return value check of platform_get_resource() is removed,
because the value is checked by devm_ioremap_resource().

rtc: rtc-jz4740: remove unnecessary platform_set_drvdata()

2013-07-03T23:07:50+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: 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-jz4740.c: fix IRQ error check

2012-10-05T18:05:03+00:00

The irq field of the jz4740_irc struct is unsigned.  Yet we assign the
result of platform_get_irq() to it.  platform_get_irq() may return a
negative error code and the code checks for this condition by checking if
'irq' is less than zero.  But since 'irq' is unsigned this test will
always be false.  Fix it by making 'irq' signed.

The issue was found using the following coccinelle semantic patch:

//
@@
type T;
unsigned T i;
@@
(
*i < 0
|
*i >= 0
)

rtc: convert drivers/rtc/* to use module_platform_driver()

2012-01-11T00:30:53+00:00

This patch converts the drivers in drivers/rtc/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

RTC: Cleanup rtc_class_ops->update_irq_enable()

2011-03-09T19:23:37+00:00

Now that the generic code handles UIE mode irqs via periodic
alarm interrupts, no one calls the
rtc_class_ops->update_irq_enable() method anymore.

This patch removes the driver hooks and implementations of
update_irq_enable if no one else is calling it.

drivers/rtc/rtc-jz4740.c: add alarm function

2010-10-28T01:03:06+00:00

Add the "alarm" function to the jz4740 RTC.  Interrupts will now be raised
when the "alarm" time is reached.
