rtc: pcf85363: fix wrong mask/val parameters in regmap_update_bits call

2023-11-20T10:59:30Z

[ Upstream commit 2be36c09b6b07306be33519e1aa70d2e2a2161bb ] The current implementation passes PIN_IO_INTA_OUT (2) as a mask and PIN_IO_INTAPM (GENMASK(1, 0)) as a value. Swap the variables to assign mask and value the right way. This error was first introduced with the alarm support. For better or worse it worked as expected because 0x02 was applied as a mask to 0x03, resulting 0x02 anyway. This will of course not work for any other value.

rtc: brcmstb-waketimer: support level alarm_irq

2023-11-20T10:59:30Z

[ Upstream commit e005a9b35b464be5b2e0194f717e90e7e496785d ] Some devices (e.g. BCM72112) use an alarm_irq interrupt that is connected to a level interrupt controller rather than an edge interrupt controller. In this case, the interrupt cannot be left enabled by the irq handler while preserving the hardware wake-up signal on wake capable devices or an interrupt storm will occur. The alarm_expired flag is introduced to allow the disabling of the interrupt when an alarm expires and to support balancing the calls to disable_irq() and enable_irq() in accordance with the existing design.

rtc: wm8350: remove unnecessary messages

The RTC core already prints a message when the RTC is registered and when registering fails, it is not necessary to have more in the driver. Acked-by: Charles Keepax Link: https://lore.kernel.org/r/20230827221643.544259-3-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: stop warning for invalid alarms when the alarm is disabled

2023-09-05T23:25:15Z

When the alarm is not enabled, it may never have been set and so we can't expect it to be valid. This will prevent the apparition of boot messages like this one: rtc rtc0: invalid alarm value: 2023-7-8 45:85:85 Link: https://lore.kernel.org/r/20230827221532.543353-1-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: pcf85363: Allow to wake up system without IRQ

2023-08-27T22:05:45Z

When wakeup-source is set in the devicetree, set up the device for using the output as interrupt instead of clock. This is similar to how other RTC devices handle this. This allows the clock chip to turn on the board when wired to do so in hardware.
