From df70aeef60839cb2732913fa41e61aba52ca942c Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Fri, 31 Jul 2015 11:43:12 +0200 Subject: clk: at91: add generated clock driver Add a new type of clocks that can be provided to a peripheral. In addition to the peripheral clock, this new clock that can use several input clocks as parents can generate divided rates. This would allow a peripheral to have finer grained clocks for generating a baud rate, clocking an asynchronous part or having more options in frequency.
