From: Linus Walleij Date: Thu, 30 Jul 2015 13:19:25 +0000 (+0200) Subject: clk/ARM: move Ux500 PRCC bases to the device tree X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5dc0fe199b358966021b015c71ca4049d0f42aa6;p=openwrt%2Fstaging%2Fblogic.git clk/ARM: move Ux500 PRCC bases to the device tree The base addresses for the Ux500 PRCC controllers are hardcoded, let's move them to the clock node in the device tree and delete the constants.
