rtc: rtc-coh901331: use platform_{get,set}_drvdata()

2013-07-03T23:07:55+00:00

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

rtc: rtc-coh901331: remove unnecessary platform_set_drvdata()

2013-07-03T23:07:49+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.

rtc: rtc-coh901331: convert coh901331_driver to dev_pm_ops

2013-04-30T01:28:39+00:00

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

rtc: rtc-coh90133: use devm_rtc_device_register()

2013-04-30T01:28:25+00:00

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

drivers/rtc/rtc-coh901331.c: use clk_prepare_enable() and clk_disable_unprepare()

2012-10-05T18:05:04+00:00

clk_prepare_enable and clk_disable_unprepare combine clk_prepare and
clk_enable, and clk_disable and clk_unprepare.  They make the code more
concise, and ensure that clk_unprepare is called when clk_enable fails.

A simplified version of the semantic patch that introduces calls to these
functions is as follows: (http://coccinelle.lip6.fr/)

//

expression e;

- clk_prepare(e);

drivers/rtc/rtc-coh901331.c: use clk_prepare/unprepare

2012-07-31T00:25:17+00:00

Make sure we prepare/unprepare the clock for the COH901331 RTC driver as
is required by the clk API especially if you use common clock.
