From 6f6682809b994fd9a61081fa0410df31481d5f7f Mon Sep 17 00:00:00 2001 From: Domen Puncer Date: Fri, 21 Sep 2007 00:00:11 +1000 Subject: [POWERPC] clk.h interface for platforms This provides an implementation of the interface for arch/powerpc using a set of function pointers in clk_functions. Platforms that want to support this interface should fill clk_functions and select CONFIG_PPC_CLOCK in Kconfig.
