| Subject: [PATCH] platform/x86: pmc_atom: Add Siemens SIMATIC IPC227E to |
| critclk_systems DMI table |
| |
| commit ad0d315b4d4e7138f43acf03308192ec00e9614d upstream. |
| |
| 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") |
