Note that #interconnect-cells is always zero and node IDs are not hardcoded anywhere. Signed-off-by: Artur Świgoń Signed-off-by: Sylwester Nawrocki --- Changes for v8: - none. Changes for v7: - adjusted to the DT property changes: "interconnects" instead of "samsung,interconnect-parent", "samsung,data-clk-ratio" instead of "bus-width". Changes for v6: - added bus-width property in bus_dmc node. Changes for v5: - adjust to renamed exynos,interconnect-parent-node property, - add properties in common exynos4412.dtsi file rather than in Odroid specific odroid4412-odroid-common.dtsi. --- arch/arm/boot/dts/exynos4412.dtsi | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/arch/arm/boot/dts/exynos4412.dtsi b/arch/arm/boot/dts/exynos4412.dtsi index e76881d..4999e68 100644 --- a/arch/arm/boot/dts/exynos4412.dtsi +++ b/arch/arm/boot/dts/exynos4412.dtsi @@ -383,6 +383,8 @@ clocks = <&clock CLK_DIV_DMC>; clock-names = "bus"; operating-points-v2 = <&bus_dmc_opp_table>; + samsung,data-clock-ratio = <4>; + #interconnect-cells = <0>; status = "disabled"; }; @@ -452,6 +454,8 @@ clocks = <&clock CLK_DIV_GDL>; clock-names = "bus"; operating-points-v2 = <&bus_leftbus_opp_table>; + interconnects = <&bus_dmc>; + #interconnect-cells = <0>; status = "disabled"; }; @@ -468,6 +472,8 @@ clocks = <&clock CLK_ACLK160>; clock-names = "bus"; operating-points-v2 = <&bus_display_opp_table>; + interconnects = <&bus_leftbus &bus_dmc>; + #interconnect-cells = <0>; status = "disabled"; };
