[PATCH 10/10] clk: mvebu: desintegrate obsolete file

Sebastian Hesselbarth sebastian.hesselbarth at gmail.com
Fri May 10 21:08:10 EDT 2013


Switch from function-centric to soc-centric clock drivers now makes
a bunch of files obsolete. This deletes all files and Kconfig options
that are not required anymore.
