From 75b985ef1e641dd990bc312e3bca7f4bae164723 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Tue, 15 Apr 2025 20:01:28 -0500 Subject: [PATCH] arm64: dts: imx8mn-beacon: Fix RTC capacitive load [ Upstream commit c3f03bec30efd5082b55876846d57b5d17dae7b9 ] Although not noticeable when used every day, the RTC appears to drift when left to sit over time. This is due to the capacitive load not being properly set. Fix RTC drift by correcting the capacitive load setting from 7000 to 12500, which matches the actual hardware configuration.
