Subject: [PATCH v1] platform/x86: pmc_atom: Add Siemens SIMATIC IPC227E to critclk_systems DMI table
Date: Thu, 7 Nov 2019 19:05:30 +0200 [thread overview]
Message-ID: <20191107170530.6115-1-andriy.shevchenko@linux.intel.com> (raw)
From: Jan Kiszka <jan.kiszka@siemens.com>
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.
Fixes: 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL")
