Subject: [PATCH] platform/x86: pmc_atom: Match all Beckhoff Automation baytrail boards with critclk_systems DMI table
Date: Mon, 12 Apr 2021 11:04:31 +0200	[thread overview]
Message-ID: <20210412090430.167463-1-linux-kernel-dev@beckhoff.com> (raw)

From: Steffen Dirkwinkel <s.dirkwinkel@beckhoff.com>

pmc_plt_clk* clocks are used for ethernet controllers so need to stay
turned on. This adds the affected board family to critclk_systems DMI
table so the clocks are marked as CLK_CRITICAL and not turned off.

This replaces the previosly listed boards with a match for the whole
device family. There are new affected boards that would otherwise need
to be listed. There are only few unaffected boards in the family and
having the clocks turned on is not an issue on those.

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