Subject: [PATCH] rtc: hym8563: enable wakeup when applicable
Git-commit: c56ac7a0f468ceb38d24db41f4446d98ab94da2d
Patch-mainline: v5.11-rc1
References: git-fixes
Enable wakeup in the hym8563 driver if the IRQ was successfully
requested or if wakeup-source is set in the devicetree.
As per the description of device_init_wakeup(), it should be enabled
for "devices that everyone expects to be wakeup sources". One would
expect this to be the case with a real-time clock.
Tested on rk3288-rock2-square, which has an IRQ configured for the
RTC. As a result, wakeup was enabled during driver initialisation.
