Acked-by: Sylwester Nawrocki <[email protected]> Kukjin, please merge this patch for v4.1. I merged the exynos3250 CMU ISP driver patch and we will have regression if $subject patch is not applied, i.e. reading /sys/kernel/debug/clk/clk_summary would cause system hang on exynos3250. > --- > arch/arm/boot/dts/exynos3250.dtsi | 4 ++++ > 1 file changed, 4 insertions(+) > > diff --git a/arch/arm/boot/dts/exynos3250.dtsi > b/arch/arm/boot/dts/exynos3250.dtsi > index 277b48b..6d6118e 100644 > --- a/arch/arm/boot/dts/exynos3250.dtsi > +++ b/arch/arm/boot/dts/exynos3250.dtsi > @@ -172,6 +172,10 @@ > compatible = "samsung,exynos3250-cmu"; > reg = <0x10030000 0x20000>; > #clock-cells = <1>; > + assigned-clocks = <&cmu CLK_MOUT_ACLK_400_MCUISP_SUB>, > + <&cmu CLK_MOUT_ACLK_266_SUB>; > + assigned-clock-parents = <&cmu CLK_FIN_PLL>, > + <&cmu CLK_FIN_PLL>; > }; > > cmu_dmc: clock-controller@105C0000 { > Thanks, Sylwester -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
