rtc: at91sam9: remove useless include

2015-09-05T11:19:13+00:00

Definitions from linux/platform_data/atmel.h are not used, remove the
include.

rtc: at91sam9: get sclk rate after enabling it

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

See help for clk_get_rate(): "obtain the current clock rate (in Hz) for a
clock source. This is only valid once the clock source has been enabled."

It currently returns the correct value but that may not stay that way.

rtc: at91sam9: remove useless check

2015-09-05T11:19:08+00:00

rtc->sclk necessarily points to a valid clocks at this point. Else the
probe would have aborted.

rtc: at91sam9: properly handle error case

2015-09-05T11:19:08+00:00

In case of a probe error, it is possible to abort after issuing
clk_prepare_enable(). Ensure the clock is disabled and unprepared in that
case.

rtc: at91sam9: rework wakeup and interrupt handling

2015-03-04T21:10:59+00:00

The IRQ line used by the RTC device is usually shared with the system timer
(PIT) on at91 platforms.

Since timers are registering their handlers with IRQF_NO_SUSPEND, we should
expect being called in suspended state, and properly wake the system up
when this is the case.

Set IRQF_COND_SUSPEND flag when registering the IRQ handler to inform
irq core that it can safely be called while the system is suspended.

drivers/rtc/rtc-at91sam9.c: constify struct regmap_config

2015-02-14T05:21:43+00:00

The regmap_config struct may be const because it is not modified by the
driver and regmap_init() accepts pointer to const.

Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2014-12-15T00:10:09+00:00

Pull driver core update from Greg KH:
 "Here's the set of driver core patches for 3.19-rc1.

  They are dominated by the removal of the .owner field in platform
  drivers.  They touch a lot of files, but they are "simple" changes,
  just removing a line in a structure.

  Other than that, a few minor driver core and debugfs changes.  There
  are some ath9k patches coming in through this tree that have been
  acked by the wireless maintainers as they relied on the debugfs
  changes.

  Everything has been in linux-next for a while"

rtc: at91sam9: use clk API instead of relying on AT91_SLOW_CLOCK

2014-11-13T15:08:01+00:00

The RTT block is using the slow clock which is accessible through the clk
API.
Use the clk API to retrieve, enable and get the slow clk rate instead of
the AT91_SLOW_CLOCK macro (which hardcodes the slow clk rate).
Doing this allows us to reference the clk thus preventing the CCF from
disabling it during the "disable unused" phase.
