[ Upstream commit 2b7cbd98495f6ee4cd6422fe77828a19e9edf87f ] Power-on Reset has a documented issue in PCF85063, refer to its datasheet, section "Software reset": "There is a low probability that some devices will have corruption of the registers after the automatic power-on reset if the device is powered up with a residual VDD level. It is required that the VDD starts at zero volts at power up or upon power cycling to ensure that there is no corruption of the registers. If this is not possible, a reset must be initiated after power-up (i.e. when power is stable) with the software reset command" Trigger SW reset if there is an indication that POR has failed.

[ Upstream commit 3ab8c5ed4f84fa20cd16794fe8dc31f633fbc70c ] The nvmem interface supports variable buffer sizes, while the regmap interface operates with fixed-size storage. If an nvmem client uses a buffer size less than 4 bytes, regmap_read will write out of bounds as it expects the buffer to point at an unsigned int.

[ Upstream commit 544c42f798e1651dcb04fb0395219bf0f1c2607e ] IRQ_DOMAIN is a hidden (not user visible) symbol. Users cannot set it directly thru "make *config", so drivers should select it instead of depending on it if they need it. Relying on it being set for a dependency is risky. Consistently using "select" or "depends on" can also help reduce Kconfig circular dependency issues. Therefore, change the use of "depends on" for IRQ_DOMAIN to "select" for RTC_DRV_MT6397.

2024-01-31rtc: Extend timeout for waiting for UIP to clear to 1sMario Limonciello
commit cef9ecc8e938dd48a560f7dd9be1246359248d20 upstream. Specs don't say anything about UIP being cleared within 10ms. They only say that UIP won't occur for another 244uS. If a long NMI occurs while UIP is still updating it might not be possible to get valid data in 10ms. This has been observed in the wild that around s2idle some calls can take up to 480ms before UIP is clear. Adjust callers from outside an interrupt context to wait for up to a 1s instead of 10ms.

2024-01-31rtc: Add support for configuring the UIP timeout for RTC readsMario Limonciello
commit 120931db07b49252aba2073096b595482d71857c upstream. The UIP timeout is hardcoded to 10ms for all RTC reads, but in some contexts this might not be enough time. Add a timeout parameter to mc146818_get_time() and mc146818_get_time_callback(). If UIP timeout is configured by caller to be >=100 ms and a call takes this long, log a warning. Make all callers use 10ms to ensure no functional changes.

2024-01-31rtc: mc146818-lib: Adjust failure return code for mc146818_get_time()Mario Limonciello
commit af838635a3eb9b1bc0d98599c101ebca98f31311 upstream. mc146818_get_time() calls mc146818_avoid_UIP() to avoid fetching the time while RTC update is in progress (UIP). When this fails, the return code is -EIO, but actually there was no IO failure. The reason for the return from mc146818_avoid_UIP() is that the UIP wasn't cleared in the time period. Adjust the return code to -ETIMEDOUT to match the behavior.

commit 3d762e21d56370a43478b55e604b4a83dd85aafc upstream. Intel systems > 2015 have been configured to use ACPI alarm instead of HPET to avoid s2idle issues. Having HPET programmed for wakeup causes problems on AMD systems with s2idle as well. One particular case is that the systemd "SuspendThenHibernate" feature doesn't work properly on the Framework 13" AMD model. Switching to using ACPI alarm fixes the issue. Adjust the quirk to apply to AMD/Hygon systems from 2021 onwards. This matches what has been tested and is specifically to avoid potential risk to older systems.

[ Upstream commit 0e6255fa3f649170da6bd1a544680589cfae1131 ] The VRTC alarm register can be programmed with an amount of seconds after which the SoC will be woken up by the VRTC timer again. We are already converting the alarm time from meson_vrtc_set_alarm() to "seconds since 1970". This means we also need to use "seconds since 1970" for the current time. This fixes a problem where setting the alarm to one minute in the future results in the firmware (which handles wakeup) to output (on the serial console) that the system will be woken up in billions of seconds. ktime_get_raw_ts64() returns the time since boot, not since 1970. Switch to ktime_get_real_ts64() to fix the calculation of the alarm time and to make the SoC wake up at the specified date/time. Also the firmware (which manages suspend) now prints either 59 or 60 seconds until wakeup (depending on how long it takes for the system to enter suspend).

If they are not identical, there is a failure at run time, which manifests as either a kernel panic or thread getting killed. msc313_rtc_probe() was passing clk_disable_unprepare() directly, which did not have matching prototypes for devm_add_action_or_reset()'s callback argument. Refactor to use devm_clk_get_enabled() instead. This was found as a result of Clang's new -Wcast-function-type-strict flag, which is more sensitive than the simpler -Wcast-function-type, which only checks for type width mismatches.
