2020-09-15rtc: rx8010: don't modify the global rtc opsBartosz Golaszewski
The way the driver is implemented is buggy for the (admittedly unlikely) use case where there are two RTCs with one having an interrupt configured and the second not. This is caused by the fact that we use a global rtc_class_ops struct which we modify depending on whether the irq number is present or not. Fix it by using two const ops structs with and without alarm operations. While at it: not being able to request a configured interrupt is an error so don't ignore it and bail out of probe().

2020-08-21rtc: rtc-rs5c313: Fix late hardware initGeert Uytterhoeven
rs5c313_rtc_init() calls platform_driver_register(), and initializes the hardware. This is wrong because of two reasons: 1. As soon as the driver has been registered, the device may be probed. If devm_rtc_device_register() is called before hardware initialization, reading the current time will fail: rs5c313 rs5c313: rs5c313_rtc_read_time: timeout error rs5c313 rs5c313: registered as rtc0 rs5c313 rs5c313: rs5c313_rtc_read_time: timeout error rs5c313 rs5c313: hctosys: unable to read the hardware clock 2. If the platform device does not exist, the driver will still write to a hardware device that may not be present.

2020-08-21rtc: cmos: zero-init wkalrm when reading from CMOSVictor Ding
cmos_read_alarm() may leave certain fields of a struct rtc_wkalrm untouched; therefore, these fields contain garbage if not properly initialized, leading to inconsistent values when converting into time64_t. This patch to zero initialize the struct before calling cmos_read_alarm(). Note that this patch is not intended to produce a correct time64_t, it is only to produce a consistent value. In the case of suspend/resume, a correct time64_t is not necessary; a consistent value is sufficient to correctly perform an equality test for t_current_expires and t_saved_expires. Logic to deduce a correct time64_t is expensive and hence should be avoided.

2020-08-07rtc: max77686: Fix wake-ups for max77620Jon Hunter
Following commit d8f090dbeafd ("rtc: max77686: Do not allow interrupt to fire before system resume"), RTC wake-ups stopped working on Jetson TX2 and Jetson Xavier platforms. The Jetson TX2 uses the max77620 PMIC and the Jetson Xavier uses max20024 PMIC. Both of these PMICs have the same max77620 RTC controller. For the max77620 RTC, the variable 'rtc_irq_from_platform' is defined as true in the max77686 driver and because of this the IRQ passed to the max77686 driver for RTC is the PMIC IRQ and not the parent. Hence, following commit d8f090dbeafd ("rtc: max77686: Do not allow interrupt to fire before system resume"), for the max77620 the RTC IRQ within the PMIC is now getting disabled on entry to suspend and unable to wake the system up. Fix this by only disabling interrupts on entry to suspend in the max77686 RTC driver, if the interrupt is the parent interrupt.

2020-07-16rtc: max77686: Do not allow interrupt to fire before system resumeKrzysztof Kozlowski
The rtc-max77686 device shares the main interrupt line with parent MFD device (max77686 driver). During the system suspend, the parent MFD device disables this IRQ to prevent an early event happening before resuming I2C bus controller. The same should be done by rtc-max77686 driver because otherwise the interrupt handler max77686_rtc_alarm_irq() will be called before its resume function (max77686_rtc_resume()). Such issue is not fatal but disabling shared IRQ by all users ensures correct behavior.
