[PATCH 3/9] arm64: dts: imx8mp-beacon: Fix RTC capacitive load
From: Adam Ford
Date: Wed Apr 09 2025 - 21:00:55 EST
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
default being 7000, when the hardware is really using 12500.
Fixing this setting to fix the drift.
