From ad0d315b4d4e7138f43acf03308192ec00e9614d Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Wed, 4 Sep 2019 08:42:30 +0200 Subject: platform/x86: pmc_atom: Add Siemens SIMATIC IPC227E to critclk_systems DMI table The SIMATIC IPC227E uses the PMC clock for on-board components and gets stuck during boot if the clock is disabled. Therefore, add this device to the critical systems list.
