From 72e1e2a30f67fc19a958be6c1818e7e6cb1573fe Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Wed, 23 Jul 2014 16:36:57 +0200 Subject: MIPS: Alchemy: remove old clock support With the clock framework in place, remove unused functions and bits, and drop the CLK_IGNORE_UNUSED flag, which is now unneeded.
