Subject: [PATCH] platform/x86: pmc_atom: Add Siemens CONNECT X300 to critclk_systems DMI table
Git-commit: e8796c6c69d129420ee94a1906b18d86b84644d4
Patch-mainline: v5.5-rc3
References: bsc#1051510
The CONNECT X300 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.
Tested on CONNECT X300.
Fixes: 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL")
