   4 Subject: platform/x86: pmc_atom: Add CB4063 Beckhoff Automation board to critclk_systems DMI table

   8 commit 9452fbf5c6cf5f470e0748fe7a14a683e7765f7a upstream.
   9
  10 The CB4063 board uses pmc_plt_clk* clocks for ethernet controllers. This
  11 adds it to the critclk_systems DMI table so the clocks are marked as
  12 CLK_CRITICAL and not turned off.

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