From 7a276effd5061d2dbec34d7b17e09c9529234631 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Tue, 15 Apr 2025 20:01:29 -0500 Subject: [PATCH] arm64: dts: imx8mp-beacon: Fix RTC capacitive load [ Upstream commit 6821ee17537938e919e8b86a541aae451f73165b ] 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.
