[PATCH v1 23/24] clk: mpc512x: switch to COMMON_CLK, remove PPC_CLOCK

Gerhard Sittig gsi at denx.de
Tue Jul 16 18:45:39 EST 2013


completely switch to, i.e. unconditionally use COMMON_CLK for the
MPC512x platform, and retire the PPC_CLOCK implementation for that
platform after the transition has completed
