The patch series generally looks good to me, I've tested it on an Exynos4412 based board. I have applied couple fixes that Tomasz Figa has sent you off the mailing list. And to make a MIPI-CSI2 camera working a small fixup patch as below. I have just one remark, but this could possibly be done as a follow up patch. Namely it may make sense to rename various sclk_* clocks to just "sclk", so for instance we don't have "fimd", "sclk_fimd", "fimc", "sclk_fimc" but e.g. "bus" or "gate" and "sclk" for each device. Such naming might be better for handling devices at core subsystems level, e.g. Runtime PM or devfreq. Please feel free to add: Reviewed-by: Sylwester Nawrocki <s.nawrocki@xxxxxxxxxxx> Tested-by: Sylwester Nawrocki <s.nawrocki@xxxxxxxxxxx> I would be great to have this patch set merged for 3.9, so people can switch earlier to the common clock API, rather than modifying files that will be removed soon. -- Regards, Sylwester >From 8382dcc93bf465e9a03f4f07426825f1a9be0ba1 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki <s.nawrocki@xxxxxxxxxxx> Date: Fri, 18 Jan 2013 19:13:52 +0100 Subject: [PATCH] clk: samsung: Correct definition of sclk_cam gate clocks sclk_cam0/1 clock gates are present on all exynos4 SoCs.
