From 70855bb5c608e4ac9dde5b669c3cf56914b713a2 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Tue, 23 Jul 2013 09:25:56 +0200 Subject: clk: sunxi: Allow to specify the divider width from the dividers data MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The divider width used to be hardcoded. Some A31 dividers are no longer with the hardcoded width, so we need to make it specific to each divider and set it in the dividers data.
