So instead, the preferred way would be to specify the clock using following layout: clocks { compatible = "simple-bus"; #address-cells = <1>; #size-cells = <0>; oscclk: clock@0 { compatible = "fixed-clock"; reg = <0>; #clock-cells = <0>; clock-frequency = <24000000>; clock-output-names = "fin_pll"; }; }; > + compatible = "fixed-clock"; > + #clock-cells = <0>; > + clock-frequency = <24000000>; > + clock-output-names = "fin_pll"; > + }; [snip] > + > +}; > diff --git a/arch/arm/boot/dts/exynos5410.dtsi b/arch/arm/boot/dts/exynos5410.dtsi > new file mode 100644 > index 0000000..9921b66 > --- /dev/null > +++ b/arch/arm/boot/dts/exynos5410.dtsi > @@ -0,0 +1,209 @@ > +/* > + * SAMSUNG EXYNOS5410 SoC device tree source > + * > + * Copyright (c) 2013 Samsung Electronics Co., Ltd. > + * http://www.samsung.com > + * > + * SAMSUNG EXYNOS5410 SoC device nodes are listed in this file. > + * EXYNOS5410 based board files can include this file and provide > + * values for board specfic bindings. > + * > + * This program is free software; you can redistribute it and/or modify > + * it under the terms of the GNU General Public License version 2 as > + * published by the Free Software Foundation. > + */ > + > +#include <dt-bindings/clock/exynos5410.h> > +#include "exynos5.dtsi" > +/ { [snip] > + clock: clock-controller@10010000 { > + compatible = "samsung,exynos5410-clock"; > + reg = <0x10010000 0x30000>; > + #clock-cells = <1>; > + }; > + > + mct@101C0000 { A generic name would be: timer@101C0000 > + compatible = "samsung,exynos4210-mct"; > + reg = <0x101C0000 0xB00>; > + interrupt-controller; > + #interrups-cells = <1>; MCT is not an interrupt controller, so both interrupt-controller and #interrupt-cells properties are incorrect. I guess that's due to the broken example in the documentation, that I already posted patches to fix. > + interrupt-parent = <&mct_map>; > + interrupts = <0>, <1>, <2>, <3>, > + <4>, <5>, <6>, <7>, > + <8>, <9>, <10>, <11>; > + clocks = <&oscclk>, <&clock CLK_MCT>; > + clock-names = "fin_pll", "mct"; > + > + mct_map: mct-map { Again, interrupt-map would be a better name for this node. > + #interrupt-cells = <1>; > + #address-cells = <0>; > + #size-cells = <0>; > + interrupt-map = <0 &combiner 23 3>, > + <1 &combiner 23 4>, > + <2 &combiner 25 2>, > + <3 &combiner 25 3>, > + <4 &gic 0 120 0>, > + <5 &gic 0 121 0>, > + <6 &gic 0 122 0>, > + <7 &gic 0 123 0>, > + <8 &gic 0 128 0>, > + <9 &gic 0 129 0>, > + <10 &gic 0 130 0>, > + <11 &gic 0 131 0>; > + }; > + }; Otherwise, the patch looks good.
