rtc-coh901331: fix braces in resume code

2010-03-15T16:07:05+00:00

commit 5a98c04d78c896d52baef20ffc11f6d1ba6eb786 upstream.

The else part of the if statement is indented but does not have braces
around it. It clearly should since it uses clk_enable and clk_disable
which are supposed to balance.

rtc_cmos: convert shutdown to new pnp_driver->shutdown

2010-01-11T17:34:07+00:00

commit abd6633c67925f90775bb74755f9c547e30f1f20 ("pnp: add a shutdown
method to pnp drivers") adds shutdown method to bus driver blindly.  With
it, driver->shutdown is no longer valid.

Use pnp_driver->shutdown instead.

rtc: set wakeup capability for I2C and SPI RTC drivers

2009-12-17T23:45:32+00:00

RTC core won't allow wakeup alarms to be set if RTC devices' parent (i.e.
i2c_client or spi_device) isn't wakeup capable.

For I2C devices there is I2C_CLIENT_WAKE flag exists that we can pass via
board info, and if set, I2C core will initialize wakeup capability.  For
SPI devices there is no such flag at all.

I believe that it's not platform code responsibility to allow or disallow
wakeups, instead, drivers themselves should set the capability if a device
can trigger wakeups.

That's what drivers/base/power/sysfs.c says:

 * It is the responsibility of device drivers to enable (or disable)
 * wakeup signaling as part of changing device power states, respecting
 * the policy choices provided through the driver model.

I2C and SPI RTC devices send wakeup events via interrupt lines, so we
should set the wakeup capability if IRQ is routed.

Ideally we should also check irq for wakeup capability before setting
device's capability, i.e.

	if (can_irq_wake(irq))
		device_set_wakeup_capable(&client->dev, 1);

But there is no can_irq_wake() call exist, and it is not that trivial to
implement it for all interrupts controllers and complex/cascaded setups.

drivers/base/power/sysfs.c also covers these cases:

 * Devices may not be able to generate wakeup events from all power
 * states.  Also, the events may be ignored in some configurations;
 * for example, they might need help from other devices that aren't
 * active

So there is no guarantee that wakeup will actually work, and so I think
there is no point in being pedantic wrt checking IRQ wakeup capability.

rtc-x1205: unconditionally set date when setting clock

2009-12-16T15:20:00+00:00

All callsites of x1205_set_datetime() want the date to be set as well, so
remove the flag parameter and set it unconditionally.
