2021-06-20rtc: max77686: Do not enforce (incorrect) interrupt trigger typeKrzysztof Kozlowski
Interrupt line can be configured on different hardware in different way, even inverted. Therefore driver should not enforce specific trigger type - edge falling - but instead rely on Devicetree to configure it. The Maxim 77686 datasheet describes the interrupt line as active low with a requirement of acknowledge from the CPU therefore the edge falling is not correct. The interrupt line is shared between PMIC and RTC driver, so using level sensitive interrupt is here especially important to avoid races. With an edge configuration in case if first PMIC signals interrupt followed shortly after by the RTC, the interrupt might not be yet cleared/acked thus the second one would not be noticed.

2021-05-25rtc: fix snprintf() checking in is_rtc_hctosys()Dan Carpenter
The scnprintf() function silently truncates the printf() and returns the number bytes that it was able to copy (not counting the NUL terminator). Thus, the highest value it can return here is "NAME_SIZE - 1" and the overflow check is dead code. Fix this by using the snprintf() function which returns the number of bytes that would have been copied if there was enough space and changing the condition from "> NAME_SIZE" to ">= NAME_SIZE".

2021-05-25rtc: m41t80: add support for fixed clockSebastian Reichel
Congatec's QMX6 system on module (SoM) uses a m41t62 as RTC. The modules SQW clock output defaults to 32768 Hz. This behaviour is used to provide the i.MX6 CKIL clock. Once the RTC driver is probed, the clock is disabled and all i.MX6 functionality depending on the 32 KHz clock has undefined behaviour. For example when using the hardware watchdog the system will likely do arbitrary reboots. Referencing the m41t62 directly results in a deadlock. The kernel will see, that i.MX6 system clock needs the RTC clock and do probe deferral. But the i.MX6 I2C module never becomes usable without the i.MX6 CKIL clock and thus the RTC's clock will not be probed. So from the kernel's perspective this is a chicken-and-egg problem. Technically everything is fine by not touching anything, since the RTC clock correctly enables the clock on reset (i.e. on battery backup power loss) and also the bootloader enables it in case an something (e.g. an unpatched kernel) disabled this incorrectly. A workaround for this issue is describing the square wave pin as fixed-clock, which is registered early and basically how this pin is used on the i.MX6.

2021-05-25rtc: bd70528: fix BD71815 watchdog dependencyArnd Bergmann
The added Kconfig dependency is slightly incorrect, which can lead to a link failure when the watchdog is a loadable module: arm-linux-gnueabi-ld: drivers/rtc/rtc-bd70528.o: in function `bd70528_set_rtc_based_timers': rtc-bd70528.c:(.text+0x6cc): undefined reference to `bd70528_wdt_set' arm-linux-gnueabi-ld: drivers/rtc/rtc-bd70528.o: in function `bd70528_set_time': rtc-bd70528.c:(.text+0xaa0): undefined reference to `bd70528_wdt_lock' arm-linux-gnueabi-ld: rtc-bd70528.c:(.text+0xab8): undefined reference to `bd70528_wdt_unlock' arm-linux-gnueabi-ld: drivers/rtc/rtc-bd70528.o: in function `bd70528_alm_enable': rtc-bd70528.c:(.text+0xfc0): undefined reference to `bd70528_wdt_lock' arm-linux-gnueabi-ld: rtc-bd70528.c:(.text+0x1030): undefined reference to `bd70528_wdt_unlock' The problem is that it allows to be built-in if MFD_ROHM_BD71828 is built-in, even when the watchdog is a loadable module. Rework this so that having the watchdog as a loadable module always forces the rtc to be a module as well instead of built-in, regardless of bd71828.

2021-04-16rtc: pcf85063: fallback to parent of_nodeFrancois Gervais
The rtc device node is always NULL. Since v5.12-rc1-dontuse/3c9ea42802a1fbf7ef29660ff8c6e526c58114f6 this will lead to a NULL pointer dereference. To fix this use the parent node which is the i2c client node as set by devm_rtc_allocate_device(). Using the i2c client node seems to be what other similar drivers do e.g. rtc-pcf8563.c.

2021-04-14rtc: bd70528: Do not require parent dataMatti Vaittinen
The ROHM BD71828 and BD71815 RTC drivers only need the regmap pointer from parent. Regmap can be obtained via dev_get_regmap() so do not require parent to populate driver data for that. BD70528 on the other hand requires parent data to access the watchdog so leave the parent data for BD70528 here for now.

2021-03-15rtc: rv3028: correct weekday register usageHeiko Schocher
The datasheet for the rv3028 says the weekday has exact 3 bits and in chapter 3.4.0 for the "3h–Weekday" register it says: """ This register holds the current day of the week. Each value represents one weekday that is assigned by the user. Values will range from 0 to 6 The weekday counter is simply a 3-bit counter which counts up to 6 and then resets to 0. """ So do not code weekday bitwise instead, use the raw values from 0-6. Tested on "PHYTEC phyBOARD-Pollux i.MX8MP" board.
