Date: Tue, 4 Jun 2019 19:21:45 -0400 From: Sasha Levin <sashal@...nel.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Steffen Dirkwinkel <s.dirkwinkel@...khoff.com>, Andy Shevchenko <andriy.shevchenko@...ux.intel.com>, Sasha Levin <sashal@...nel.org>, platform-driver-x86@...r.kernel.org Subject: [PATCH AUTOSEL 5.1 35/60] platform/x86: pmc_atom: Add several Beckhoff Automation boards to critclk_systems DMI table From: Steffen Dirkwinkel <s.dirkwinkel@...khoff.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.
