   4 Subject: platform/x86: pmc_atom: Add several Beckhoff Automation boards to
   5  critclk_systems DMI table
   6
   7 [ Upstream commit d6423bd03031c020121da26c41a26bd5cc6d0da3 ]
   8
   9 There are several Beckhoff Automation industrial PC boards which use
  10 pmc_plt_clk* clocks for ethernet controllers. This adds affected boards
  11 to critclk_systems DMI table so the clocks are marked as CLK_CRITICAL and
  12 not turned off.

  14 Fixes: 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL")
