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")
