* rtc-m48t59 driver NO_IRQ mode fixupMark Zhan2007-07-31
| | | | | | | | | | | | | | | | Since irq in m48t59_private struct is defined as 'unsigned int', which will make the following if sentence to be never true: if (m48t59->irq < 0) m48t59->irq = NO_IRQ; And thus it will make the m48t59_rtc_probe() is failed when the driver is working in a no irq mode: Signed-off-by: Mark Zhan <rongkai.zhan@windriver.com> Acked-by: Alessandro Zummo <a.zummo@towertech.it> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* | Cleanup non-arch xtime uses, use get_seconds() or current_kernel_time().john stultz2007-07-25
|/ | | | | | | | | | | | | | | | | | This avoids use of the kernel-internal "xtime" variable directly outside of the actual time-related functions. Instead, use the helper functions that we already have available to us. This doesn't actually change any behaviour, but this will allow us to fix the fact that "xtime" isn't updated very often with CONFIG_NO_HZ (because much of the realtime information is maintained as separate offsets to 'xtime'), which has caused interfaces that use xtime directly to get a time that is out of sync with the real-time clock by up to a third of a second or so.

* OMAP: add TI TWL92330/Menelaus Power Management chip driverTony Lindgren2007-07-17
| | | | | | | | | | | | | | | | | | | | | | Add Texas Instruments TWL92330/Menelaus Power Management chip driver. This includes voltage regulators, Dual slot memory card tranceivers and real-time clock(RTC). The support for RTC is integrated with this driver only; it is not separate module. Passes 'rtctest' on OMAP H4 EVM, other than lack of "periodic" (1/N second) IRQs. System wakeup alarms (from suspend-to-RAM) work too. The battery keeps the RTC active over power off, so once you set clock (rdate/ntpdate/etc, then "hwclock -w") then RTC_HCTOSYS at boot time will behave as expected.

What I do: Adding a new parameter "struct bin_attribute *" in the .read/.write methods for the sysfs binary attributes. In fact, only the four lines change in fs/sysfs/bin.c and include/linux/sysfs.h do the real work. But I have to update all the files that use binary attributes to make them compatible with the new .read and .write methods. I'm not sure if I missed any. :( Why I do this: For a sysfs attribute, we can get a pointer pointing to the struct attribute in the .show/.store method, while we can't do this for the binary attributes. I don't know why this is different, but this does make it not so handy to use the binary attributes as the regular ones. So I think this patch is reasonable. :) Who benefits from it: The patch that exposes ACPI tables in sysfs requires such an improvement. All the table binary attributes share the same .read method. Parameter "struct bin_attribute *" is used to get the table signature and instance number which are used to distinguish different ACPI table binary attributes. Without this parameter, we need to offer different .read methods for different ACPI table binary attributes. This is impossible as there are various ACPI tables on different platforms, and we don't know what they are until they are loaded.

| * | sysfs: kill unnecessary attribute->ownerTejun Heo2007-07-11
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

| | | | | | | | | | | | | Intel Macs (and possibly other machines) provide a PNP entry for the RTC, but provide no IRQ. As a result the rtc-cmos driver doesn't allow wakeup alarms. If the RTC is located at the legacy ioport range, assume that it's on IRQ 8 unless the tables say otherwise.
