From e663c703b16b515ce0038f971c5d10d33884869b Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Tue, 27 Aug 2019 06:25:58 +0000 Subject: [PATCH] imx8m: soc: probe clock device in arch_cpu_init_dm Because we need to get cpu freq in print_cpuinfo at very early stage, so we need to make sure the ccm be probed.
