ARM: drivers/rtc/rtc-at91rm9200.c: disable interrupts at shutdown

2013-11-22T00:42:27+00:00

Make sure RTC-interrupts are disabled at shutdown.

As the RTC is generally powered by backup power (VDDBU), its interrupts
are not disabled on wake-up, user, watchdog or software reset.  This
could cause troubles on other systems (e.g.  older kernels) if an
interrupt occurs before a handler has been installed at next boot.

Let us be well-behaved and disable them on clean shutdowns at least (as
do the RTT-based rtc-at91sam9 driver).

alpha: Reorganize rtc handling

2013-11-17T00:33:16+00:00

Discontinue use of GENERIC_CMOS_UPDATE; rely on the RTC subsystem.

The marvel platform requires that the rtc only be touched from the
boot cpu.  This had been partially implemented with hooks for
get/set_rtc_time, but read/update_persistent_clock were not handled.
Move the hooks from the machine_vec to a special rtc_class_ops struct.

We had read_persistent_clock managing the epoch against which the
rtc hw is based, but this didn't apply to get_rtc_time or set_rtc_time.
This resulted in incorrect values when hwclock(8) gets involved.

Allow the epoch to be set from the kernel command-line, overriding
the autodetection, which is doomed to fail in 2020.  Further, by
implementing the rtc ioctl function, we can expose this epoch to
userland.

Elide the alarm functions that RTC_DRV_CMOS implements.  This was
highly questionable on Alpha, since the interrupt is used by the
system timer.

tree-wide: use reinit_completion instead of INIT_COMPLETION

2013-11-15T00:32:21+00:00

Use this new function to make code more comprehensible, since we are
reinitialzing the completion, not initializing.

drivers/rtc/rtc-hid-sensor-time.c: enable HID input processing early

2013-11-15T00:32:21+00:00

Enable the processing of HID input records before the RTC will be
registered, in order to allow the RTC register function to read clock.
Without doing that the clock can only be read after the probe function
has finished.

drivers/rtc/rtc-hid-sensor-time.c: use dev_get_platdata()

2013-11-15T00:32:21+00:00

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.  This is a cosmetic change to
make the code simpler and enhance the readability.

drivers/rtc/rtc-as3722: add RTC driver

2013-11-13T03:09:31+00:00

The ams AS3722 is a compact system PMU suitable for mobile phones, tablets
etc.

Add a driver to support accessing the RTC found on the ams AS3722 PMIC
using RTC framework.

drivers/rtc/rtc-puv3.c: use dev_dbg() instead of pr_debug()

2013-11-13T03:09:31+00:00

Because dev_*() are used along with pr_debug() function in this code, the
debug message is not tidy.  This patch converts from pr_debug() to
dev_dbg() since dev_*() are encouraged to use in device driver code.
