rtc: at91sam9: Fix missing spin_lock_init()

2016-07-25T22:09:18Z

The driver allocates the spinlock but not initialize it. Use spin_lock_init() on it to initialize it correctly. This is detected by Coccinelle semantic patch. Signed-off-by: Wei Yongjun Signed-off-by: Alexandre Belloni

rtc: at91sam9: remove duplicate assignment of variable mr

2016-05-20T10:33:51Z

mr is written twice with the same value, remove one of the redundant assignments to mr. Signed-off-by: Colin Ian King Signed-off-by: Alexandre Belloni

rtc: at91sam9: remove useless include

2015-09-05T11:19:13Z

Definitions from linux/platform_data/atmel.h are not used, remove the include. Signed-off-by: Alexandre Belloni

rtc: at91sam9: include linux/of.h

2015-09-05T11:19:12Z

This driver is using device tree but is not including of.h Signed-off-by: Alexandre Belloni

rtc: at91sam9: get sclk rate after enabling it

2015-09-05T11:19:09Z

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. Signed-off-by: Alexandre Belloni Acked-by: Boris Brezillon Acked-by: Nicolas Ferre

rtc: at91sam9: sort headers alphabetically

rtc: at91sam9: remove useless check

2015-09-05T11:19:08Z

rtc->sclk necessarily points to a valid clocks at this point. Else the probe would have aborted. Signed-off-by: Alexandre Belloni Acked-by: Boris Brezillon Acked-by: Nicolas Ferre

rtc: at91sam9: properly handle error case

2015-09-05T11:19:08Z

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. Signed-off-by: Alexandre Belloni Acked-by: Boris Brezillon Acked-by: Nicolas Ferre

rtc: at91sam9: rework wakeup and interrupt handling

2015-03-04T21:10:59Z

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

2015-02-14T05:21:43Z

The regmap_config struct may be const because it is not modified by the driver and regmap_init() accepts pointer to const. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
