Pull driver core update from Greg KH:
"Here's the set of driver core patches for 3.19-rc1.They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes,
just removing a line in a structure.Other than that, a few minor driver core and debugfs changes. There
are some ath9k patches coming in through this tree that have been
acked by the wireless maintainers as they relied on the debugfs
changes.Everything has been in linux-next for a while"

Commit 7654e9d4fd8f ("drivers/rtc/rtc-snvs: fix suspend/resume")
replaces SIMPLE_DEV_PM_OPS with direct declaration of snvs_rtc_pm_ops,
but does so outside #ifdef CONFIG_PM_SLEEP. This causes the driver
build to fail if CONFIG_PM_SLEEP is not configured.Fixes: 7654e9d4fd8f ("drivers/rtc/rtc-snvs: fix suspend/resume")

Pull powerpc updates from Michael Ellerman:
"Some nice cleanups like removing bootmem, and removal of
__get_cpu_var().There is one patch to mm/gup.c. This is the generic GUP
implementation, but is only used by us and arm(64). We have an ack
from Steve Capper, and although we didn't get an ack from Andrew he
told us to take the patch through the powerpc tree.There's one cxl patch. This is in drivers/misc, but Greg said he was
happy for us to manage fixes for it.There is an infrastructure patch to support an IPMI driver for OPAL.
There is also an RTC driver for OPAL. We weren't able to get any

rtc_timer_do_work() only judges -ETIME failure of__rtc_set_alarm(), but
doesn't handle other failures like -EIO, -EBUSY, etc.If there is a failure other than -ETIME, the next rtc_timer will stay in
the timerqueue. Then later rtc_timers will be enqueued directly because
they have a later expires time, so the alarm irq will never be programmed.When such failures happen, this patch will retry __rtc_set_alarm(), if
still can't program the alarm time, it will remove current rtc_timer from
timerqueue and fetch next one, thus preventing it from affecting other rtc
timers.Signed-off-by: Xunlei Pang

Currently, ab8500 doesn't set uie_unsupported of rtc_device, while it
doesn't support UIE, see ab8500_rtc_set_alarm().Thus, when going through rtc_update_irq_enable()->rtc_timer_enqueue(),
there's a chance it has an alarm timer1 queued before which is going to
fired, so this update timer2 will be queued because it isn't the leftmost
one, which means rtc_timer_enqueue() will return 0.This will result in two problems:
1) UIE EMUL will not be used.
2) When the alarm timer1 is fired, in rtc_timer_do_work() timer2 will
fail to set the alarm time, so this rtc will disfunctional due to
timer2 with the earliest expires in the timerqueue.So, rtc drivers must set this flag if they don't support UIE.

The alarm interrupt handler also reads registers which are part of SNVS

IRQ's have been enabled, hence this leads to a abort:Unhandled fault: external abort on non-linefetch (0x1008) at 0x908c604c

Add clock enable and disable support for the SNVS peripheral, which is
required for using the RTC within the SNVS block.The clock is not strictly enforced, as this would break the i.MX devices.
The clocking for the i.MX devices seems to be enabled elsewhere and
enabling RTC SNVS for Vybrid results in a crash. This patch adds the
clock support but also makes it optional so Vybrid platform can use the
clock if defined while making sure not to break i.MX.Signed-off-by: Sanchayan Maity

unconditionally at driver load, this patch adds proper handling of the
flag. The driver now returns -ENODATA when reading time from the device
and oscillator failure bit is set. The flag is now cleared only when the

The month register of ISL12057 RTC chip includes a century bit which
reports overflow of year register from 99 to 0. This bit can also be
written, which allows using it to extend the time interval the chip can
support from 99 to 199 years.This patch adds support for century overflow bit in tm to regs and regs to
tm helpers in ISL12057 driver.This was tested by putting a device 100 years in the future (using a
specific kernel due to the inability of userland tools such as date or
hwclock to pass year 2038), rebooting on a kernel w/ this patch applied
and verifying the device was still 100 years in the future.Signed-off-by: Arnaud Ebalard

When Intersil ISL12057 support was added by commit 70e123373c05 ("rtc: Add
support for Intersil ISL12057 I2C RTC chip"), two masks for time registers
values imported from the device were either wrong or omitted, leading to
additional bits from those registers to impact read values:- mask for hour register value when reading it in AM/PM mode. As
AM/PM mode is not the usual mode used by the driver, this error
would only have an impact on an externally configured RTC hour
later read by the driver.
- mask for month value. The lack of masking would provide an
erroneous value if century bit is set.This patch fixes those two masks.
