[PATCHv3 3/4] ARM: socfpga: dts: add clocks to the Arria10 platform

From: dinguyen
Date: Thu May 07 2015 - 11:17:50 EST


From: Dinh Nguyen <dinguyen@xxxxxxxxxxxxxxxxxxxxx>

Add all the clock nodes for the Arria10 platform. At the same time, update
the peripherals with their respective clocks property.

Signed-off-by: Dinh Nguyen <dinguyen@xxxxxxxxxxxxxxxxxxxxx>
---
v2: Add the l4_sys_free_clk node
