[PATCH] platform/x86: pmc_atom: Add CB4063 Beckhoff Automation board to critclk_systems DMI table

From: linux-kernel-dev
Date: Tue Jun 18 2019 - 09:44:09 EST


From: Steffen Dirkwinkel <s.dirkwinkel@xxxxxxxxxxxx>

The CB4063 board uses pmc_plt_clk* clocks for ethernet controllers. This
adds it to the 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")
