From dcf861e0a71906903189baed4817a90e37dc78cc Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Thu, 18 Apr 2019 17:04:10 +0200 Subject: [PATCH] platform: x86: Add Lex 3I380D industrial PC to critclk_systems DMI table The Lex 3I380D industrial PC has 4 ethernet controllers on board which need pmc_plt_clk0 - 3 to function, add it to the critclk_systems DMI table, so that drivers/clk/x86/clk-pmc-atom.c will mark the clocks as CLK_CRITICAL and they will not get turned off.
