Subject: [PATCH] rtc: at91rm9200: use of_device_get_match_data()
Date: Thu, 26 Sep 2019 15:15:32 +0300	[thread overview]
Message-ID: <1569500132-21164-1-git-send-email-claudiu.beznea@microchip.com> (raw)

Use of_device_get_match_data() since all platforms should now use DT
bindings. AVR32 architecture has been removed in
commit 26202873bb51 ("avr32: remove support for AVR32 architecture").
