From 6e91c06a73547d165bdede2b57af4acd66c0d40f Mon Sep 17 00:00:00 2001 From: Frieder Schrempf Date: Mon, 9 Jan 2023 12:42:18 +0100 Subject: [PATCH] arm64: dts: imx8mm-kontron: Add RTC aliases Add aliases for the RTCs on the board and on the SoC. This ensures that the primary RTC is always the one on the board that has a buffered supply and maximum accuracy. This is a direct port of the pending commit from linux-next.
