If anyone has any objections, please let me know. ------------------ From: Adam Ford [ 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.
