453e01cc6d rtc: hctosys: Add missing range error reporting
commit 7ce9a992ff upstream.

Fix an issue with the 32-bit range error path in `rtc_hctosys' where no
error code is set and consequently the successful preceding call result
from `rtc_read_time' is propagated to `rtc_hctosys_ret'.  This in turn
makes any subsequent call to `hctosys_show' incorrectly report in sysfs
that the system time has been set from this RTC while it has not.

Set the error to ERANGE then if we can't express the result due to an
overflow.

af1ecd4b5f rtc: ensure rtc_set_alarm fails when alarms are not supported
[ Upstream commit abfdff44bc ]

When using RTC_ALM_SET or RTC_WKALM_SET with rtc_wkalrm.enabled not set,
rtc_timer_enqueue() is not called and rtc_set_alarm() may succeed but the
subsequent RTC_AIE_ON ioctl will fail. RTC_ALM_READ would also fail in that
case.

Ensure rtc_set_alarm() fails when alarms are not supported to avoid letting
programs think the alarms are working for a particular RTC when they are
not.

cf4c7b3ab6 rtc: tx4939: avoid unintended sign extension on a 24 bit shift
[ Upstream commit 347876ad47 ]

The shifting of buf[5] by 24 bits to the left will be promoted to
a 32 bit signed int and then sign-extended to an unsigned long. If
the top bit of buf[5] is set then all then all the upper bits sec
end up as also being set because of the sign-extension. Fix this by
casting buf[5] to an unsigned long before the shift.

0cf2a2141a rtc: hctosys: Ensure system time doesn't overflow time_t
[ Upstream commit b3a5ac42ab ]

On 32bit platforms, time_t is still a signed 32bit long. If it is
overflowed, userspace and the kernel cant agree on the current system time.
This causes multiple issues, in particular with systemd:
https://github.com/systemd/systemd/issues/1143

A good workaround is to simply avoid using hctosys which is something I
greatly encourage as the time is better set by userspace.

However, many distribution enable it and use systemd which is rendering the
system unusable in case the RTC holds a date after 2038 (and more so after
2106). Many drivers have workaround for this case and they should be
eliminated so there is only one place left to fix when userspace is able to
cope with dates after the 31bit overflow.

d9bc96c4dc rtc: snvs: Fix usage of snvs_rtc_enable
[ Upstream commit 1485991c02 ]

commit 179a502f8c ("rtc: snvs: add Freescale rtc-snvs driver") introduces
the SNVS RTC driver with a function snvs_rtc_enable().

snvs_rtc_enable() can return an error on the enable path however this
driver does not currently trap that failure on the probe() path and
consequently if enabling the RTC fails we encounter a later error spinning
forever in rtc_write_sync_lp().

This patch fixes by parsing the result of rtc_write_sync_lp() and
propagating both in the probe and elsewhere. If the RTC doesn't start we
don't proceed loading the driver and don't get into this loop mess later
on.

dcd5dd9083 rtc: interface: Validate alarm-time before handling rollover
[ Upstream commit da96aea0ed ]

In function __rtc_read_alarm() its possible for an alarm time-stamp to
be invalid even after replacing missing components with current
time-stamp. The condition 'alarm->time.tm_year < 70' will trigger this
case and will cause the call to 'rtc_tm_to_time64(&alarm->time)'
return a negative value for variable t_alm.

While handling alarm rollover this negative t_alm (assumed to seconds
offset from '1970-01-01 00:00:00') is converted back to rtc_time via
rtc_time64_to_tm() which results in this error log with seemingly
garbage values:

"rtc rtc0: invalid alarm value: -2-1--1041528741
2005511117:71582844:32"

This error was generated when the rtc driver (rtc-opal in this case)
returned an alarm time-stamp of '00-00-00 00:00:00' to indicate that
the alarm is disabled. Though I have submitted a separate fix for the
rtc-opal driver, this issue may potentially impact other
existing/future rtc drivers.

To fix this issue the patch validates the alarm time-stamp just after
filling up the missing datetime components and if rtc_valid_tm() still
reports it to be invalid then bails out of the function without
handling the rollover.

756b0f10ff rtc: opal: Handle disabled TPO in opal_get_tpo_time()
[ Upstream commit 6dc1cf6f93 ]

On PowerNV platform when Timed-Power-On(TPO) is disabled, read of
stored TPO yields value with all date components set to '0' inside
opal_get_tpo_time(). The function opal_to_tm() then converts it to an
offset from year 1900 yielding alarm-time == "1900-00-01
00:00:00". This causes problems with __rtc_read_alarm() that
expecting an offset from "1970-00-01 00:00:00" and returned alarm-time
results in a -ve value for time64_t. Which ultimately results in this
error reported in kernel logs with a seemingly garbage value:

"rtc rtc0: invalid alarm value: -2-1--1041528741
2005511117:71582844:32"

We fix this by explicitly handling the case of all alarm date-time
components being '0' inside opal_get_tpo_time() and returning -ENOENT
in such a case. This signals generic rtc that no alarm is set and it
bails out from the alarm initialization flow without reporting the
above error.

3b6b68743e rtc: cmos: Do not assume irq 8 for rtc when there are no legacy irqs
[ Upstream commit a1e23a42f1 ]

On some systems (e.g. Intel Bay Trail systems) the legacy PIC is not
used, in this case virq 8 will be a random irq, rather then hw_irq 8
from the PIC.

Requesting virq 8 in this case will not help us to get alarm irqs and
may cause problems for other drivers which actually do need virq 8,
for example on an Asus Transformer T100TA this leads to:

[ 28.745155] genirq: Flags mismatch irq 8. 00000088 (mmc0) vs. 00000080 (rtc0)
<snip oops>
[ 28.753700] mmc0: Failed to request IRQ 8: -16
[ 28.975934] sdhci-acpi: probe of 80860F14:01 failed with error -16

This commit fixes this by making the rtc-cmos driver continue
without using an irq rather then claiming irq 8 when no irq is
specified in the pnp-info and there are no legacy-irqs.

99863c1bfd rtc-opal: Fix handling of firmware error codes, prevent busy loops
commit 5b8b580630 upstream.

According to the OPAL docs:
  skiboot-5.2.5/doc/opal-api/opal-rtc-read-3.txt
  skiboot-5.2.5/doc/opal-api/opal-rtc-write-4.txt

OPAL_HARDWARE may be returned from OPAL_RTC_READ or OPAL_RTC_WRITE and
this indicates either a transient or permanent error.

Prior to this patch, Linux was not dealing with OPAL_HARDWARE being a
permanent error particularly well, in that you could end up in a busy
loop.

This was not too hard to trigger on an AMI BMC based OpenPOWER machine
doing a continuous "ipmitool mc reset cold" to the BMC, the result of
that being that we'd get stuck in an infinite loop in
opal_get_rtc_time().

We now retry a few times before returning the error higher up the
stack.

The RK817 & RK809 chip is a power management IC for multimedia and handheld
devices. It contains the following components:

- Regulators
- RTC
- Clkout
- Pinctrl
- Powerkey

The RK817 & RK809 core driver is registered as a platform driver and provides
communication through I2C with the host device for the different
components.

The following is the different between the RK817 and the RK809.
1、The dcdc-buck5 is a boost dcdc for RK817 and is a buck for RK809.
2、The RK817 have one switch but The Rk809 have two.
3、The RK817 have a charger and powerpatch function but RK809 not.

600b973fc5 rtc: pcf8563: fix output clock rate
[ Upstream commit a3350f9c57 ]

The pcf8563_clkout_recalc_rate function erroneously ignores the
frequency index read from the CLKO register and always returns
32768 Hz.

Fixes: a39a6405d5 ("rtc: pcf8563: add CLKOUT to common clock framework")
