    Subject[PATCH AUTOSEL 4.19 23/36] platform/x86: pmc_atom: Add several Beckhoff Automation boards to critclk_systems DMI table
    Date
    From: Steffen Dirkwinkel <s.dirkwinkel@beckhoff.com>

    [ Upstream commit d6423bd03031c020121da26c41a26bd5cc6d0da3 ]

    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")
