Subject: [PATCH] ARM: dts: imx53: enable PMIC RTC on imx53-qsrb
Date: Sat, 11 Oct 2025 06:02:51 +0000 [thread overview]
Message-ID: <20251011060251.13356-1-akurz@blala.de> (raw)
The RTC inside mc34708 is supported by RTC_DRV_MC13XXX since v3.6-rc1.
Enable the PMIC RTC on the imx53-qsrb. Without a battery the RTC may be
powered via the micro-USB connector when main 5V power is not available.
