Some rtc drivers use the ioctl method instead of the alarm_irq_enable method for enabling alarm interupts. With the new virtualized RTC rework, its important for drivers to use the alarm_irq_enable instead. This patch converts the drivers that use the AIE ioctl method to use the alarm_irq_enable method. Other ioctl cmds are left untouched. I have not been able to test or even compile most of these drivers. Any help to make sure this change is correct would be appreciated!

The ds1307 driver misreads the ds1388 registers when checking for 12 or 24 hour mode. Instead of checking the hour register it reads the minute register. Therefore the driver thinks minutes >= 40 has the 12HR bit set and resets the minute register by zeroing the high bits. This results in minutes are reset to 0-9, jumping back in time 40 or 50 minutes. The time jump is also written back to the RTC.

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.

Tejun's commit 7b595756 made sysfs attribute->owner unnecessary. But the field was left in the structure to ease the merge. It's been over a year since that change and it is now time to start killing attribute->owner along with its users - one arch at a time! This patch is attempt #1 to get rid of attribute->owner only for CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on as and when possible - avr32 will be the next since that is something I can test. Compile (make allyesconfig / make allmodconfig / custom config) and boot tested. akpm: the idea is that we put the declaration of sttribute.owner inside `#ifndef CONFIG_X86'. But that proved to be too ambitious for now because new usages kept on turning up in subsystem trees.

This updates the rtc-ds1307 driver so that converting it to a "new style" driver (driver model, not legacy i2c model) will involve fewer changes. - Use pointer to i2c_client almost everywhere, so that it's easy to let the i2c core create that object; - Avoid using i2c_client.adapter, since that field is redundant and thus may go away (same object as i2c_client.dev.parent). - Extend type enum to include various RTCs this is expected to work with, and include register support for them. It also cleans up the support for multiple chip types, and fixes a glitch that could appear with an un-initialized RTC.

Update RTC framework so that drivers can constify their method tables, moving them from ".data" to ".rodata". Then update the drivers.

This is an "RTC-framework" driver for DS1307 and similar RTC chips, It should be a full replacement for the existing ds1337.c driver (using the older RTC glue), giving a net increase in the number of RTC chips that work out-of-the-box. There's a whole cluster of RTCs that are very similar, but the 1337 driver was a bit too picky to work with most of them. Still no support for RTC alarm IRQs (on chips that support them).
