[PATCH 23/24] clk: ti: move some public definitions to private header

Fri Mar 6 04:28:58 PST 2015


Several exported TI clock driver features are no longer needed outside
the clock driver itself, thus move all of these to the driver private
header file. Also, update some of the driver files to actually include
this header.
