From: Ulf Hansson Date: Wed, 10 Oct 2012 11:42:28 +0000 (+0200) Subject: clk: ux500: Add armss clk and fixup smp_twd clk for u8500 X-Git-Tag: next-20121112~10^2~12 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d6e99fa4f45a5f3c3029979680cf69c5a0579e6b;p=karo-tx-linux.git clk: ux500: Add armss clk and fixup smp_twd clk for u8500 The new armss clk is a prcmu_scalable_rate clk which represents the ARMSS clk. This then makes it possible to convert the smp_twd clk to a fixed factor clock type, using a fixed divider of 2 and with the armss clk as parent.
