But in reality all Exynos clock drivers are passing CPU_SRC register address via CPU_CLK() macro, which in turn gets assigned to mentioned .ctrl_base field. Because CPU_SRC address usually already has 0x200 offset from controller's base, all other register offsets in clk-cpu.c (like DIVs and MUXes) are specified as offsets from CPU_SRC offset, and not from controller's base. That makes things confusing and not consistent with register offsets provided in Exynis clock drivers, also breaking the contract for .ctrl_base field as described in struct exynos_cpuclk doc. Rework all register offsets in clk-cpu.c to be actual offsets from controller's base, and fix offsets provided to CPU_CLK() macro in all Exynos clock drivers. No functional change.
