This is a note to let you know that I've just added the patch titled clk: sunxi: Support factor clocks with N factor starting not from 0 to the 3.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: clk-sunxi-support-factor-clocks-with-n-factor-starting-not-from-0.patch and it can be found in the queue-3.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 9a5e6c7eb5ccbb5f0d3a1dffce135f0a727f40e1 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai <wens@xxxxxxxx> Date: Thu, 26 Jun 2014 23:55:41 +0800 Subject: clk: sunxi: Support factor clocks with N factor starting not from 0 From: Chen-Yu Tsai <wens@xxxxxxxx> commit 9a5e6c7eb5ccbb5f0d3a1dffce135f0a727f40e1 upstream. The PLLs on newer Allwinner SoC's, such as the A31 and A23, have a N multiplier factor that starts from 1, not 0. This patch adds an option to the factor clk driver's config data structures to specify the base value of N.
