platform/x86: pmc_atom: Add several Beckhoff Automation boards to critclk_systems DMI table

d6423bd0 · Steffen Dirkwinkel <[email protected]> · 2019-05-02 15:03:51 +02:00

There are several Beckhoff Automation industrial PC boards which use
pmc_plt_clk* clocks for ethernet controllers. This adds affected boards
to critclk_systems DMI table so the clocks are marked as CLK_CRITICAL and
not turned off.

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