From e19f2b313e2dfb155b48d25af3c8b9e73e7216b9 Mon Sep 17 00:00:00 2001 From: Uwe Poeche Date: Mon, 14 Jul 2025 15:43:37 +0200 Subject: [PATCH] mb/siemens/mc_ehl6: Enable PCHHOT_N via GPIO This mainboard uses native function two of GPIO B23 (PCHHOT_N) to realise overtemperature behaviour of the mainboard. TEST=Check the signal during HW commissioning and influence of heat to the CPU.
