* | rtc: set wakeup capability for I2C and SPI RTC driversAnton Vorontsov2009-12-173-0/+6
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | The rtc-omap driver currently assumes that the rtc's registers are at a fixed address and already mapped into virtual memory space. Remove those assumptions so the same driver can be used for similar devices that reside at different physical addresses (e.g., TI's DA8xx/OMAP-L13x SoC's).

| | | | | | | | | | | | | | | | | | | | | | | I noticed that rtc wont generate interrupts after a resume from disk. Here hpet rtc emulation is used. Problem is that rtc hpet comparator, isn't reinitialized after resume. Easiest way to solve this, is always mask all hpet interrupts on suspend This is triggered, when suspending with alarm set. Otherwise, hpet driver will think it doesn't need to reinitialize the rtc comparator, thus rtc interrupts won't work. This emulation isn't need for wakealarm.

| | | | | | | | | | | | | | | | | | | | Bring the WM8350 IRQ API more in line with the generic IRQ API by masking and unmasking interrupts as they are requested and freed. This is mostly just a case of deleting the mask and unmask calls from the individual drivers. The RTC driver is changed to mask the periodic IRQ after requesting it rather than only unmasking the alarm IRQ. If the periodic IRQ fires in the period where it is reqested then there will be a spurious notification but there should be no serious consequences from this. The CODEC drive is changed to explicitly disable headphone jack detection prior to requesting the IRQs. This will avoid the IRQ firing with no jack set up.

Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

However, the clock's _date_ might still be bogus and a subsequent probe fails when sanity-checking these values. Change the power-failure fixup code to do a full setting of rtc_time, including a valid date.

| * | | rtc-x1205: fix rtc_time to y2k register value conversionJohannes Weiner2009-12-011-1/+1

The function translating rtc_time to register values assumes tm_year to be years since first christmas, though, and we end up storing 0 or 1 in the CCR_Y2K register, which the hardware does not refuse to do. A subsequent probing of the clock fails due to the invalid value range in the register, though. [ And if it didn't, reading the clock would yield a bogus year because the function translating registers to tm_year is assuming a register value of 19 or 20. ] This fixes the conversion from years since 1900 in tm_year to the corresponding CCR_Y2K value of 19 or 20.
