From 6f65e75a8a80e6317729f232f135ca2cc5b99d4e Mon Sep 17 00:00:00 2001 From: Christophe Leroy <christophe.leroy@c-s.fr> Date: Thu, 6 Jul 2017 10:33:19 +0200 Subject: [PATCH] powerpc, 8xx: Properly set CPM frequency in the device tree For processors whose core runs at twice the bus frequency, the fallback frequency calculation in Linux provides a wrong result. Therefore, U-boot needs to pass the correct value.
