From 810cb19003ffe0115d10700fc512a2a743916f20 Mon Sep 17 00:00:00 2001 From: Bill Cook Date: Wed, 25 May 2011 15:51:07 -0400 Subject: [PATCH] MPC83XX: Fix PCI express clock setup On a 8308 based board it was found that the PEX_GLK_RATIO register (programmed in arch/powerpc/cpu/mpc83xx/pcie.c) was getting set to 0, This was tracked to the fact that the pci express clock frequency was not being assigned to the pciexp1_clk entry in the global data structure in file arch/powerpc/cpu/mpc83xx/speed.c. Fix this and a similiar issue in 'do_clocks' command.
