* rtc: rtc-twl4030 don't mask alarm interrupts on suspendKim Kyuwon2009-05-121-3/+1
| | | | | | | | | | | | | | This patch enables the alarm interrupt of TWL4030 RTC to wake up the system from suspend. You can test this patch with following command. # echo +10 > /sys/class/rtc/rtc0/wakealarm; echo mem > /sys/power/state; Signed-off-by: Kim Kyuwon <q1.kim@samsung.com> Acked-by: David Brownell <david-b@pacbell.net> Cc: Kyungmin Park <kyungmin.park@samsung.com> Cc: Alessandro Zummo <a.zummo@towertech.it> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * rtc: rtc-sh: use set_irq_wake()Magnus Damm2009-04-021-0/+36
| | | | | | | | | | | | | | | | | | | | Modify the sh_rtc driver to use set_irq_wake() during suspend and resume. These functions are used to enable the rtc interrupts in the interrupt controller so the rtc can be used to wakeup the system from suspend.

* proc 2/2: remove struct proc_dir_entry::ownerAlexey Dobriyan2009-03-311-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

|/ | | | | | | | | | | | | | | | | | | The remaining registers are separated into: - <mach/regs-ost.h> - <mach/regs-rtc.h> - <mach/regs-intc.h> and then we can remove pxa-regs.h completely. Instead of #include this file, let's: 1. include the specific <mach/regs-*.h> with care (if that's absolutely necessary) 2. define the registers in the driver, make cleanly defined API to expose the register access to external with sufficient reason Signed-off-by: Eric Miao <eric.miao@marvell.com>

| | | | | | | | | | | | Simple RTC driver for the MSP430 firmware on the DM355 EVM board. Other than not supporting atomic reads/writes of all four bytes, this is reasonable as a basic no-alarm RTC.

| | | | | | | | | | | | | | A triggering RTC alarm should be able to power on a device that has been powered off. This patch enables that on twl4030 by not masking the alarm interrupt at shutdown.
