From c56ac7a0f468ceb38d24db41f4446d98ab94da2d Mon Sep 17 00:00:00 2001 From: Guillaume Tucker Date: Fri, 6 Nov 2020 09:06:31 +0000 Subject: [PATCH] rtc: hym8563: enable wakeup when applicable 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.
