In Exynos5 series SoCs, PMU has registers to enable/disable mask/unmask watchdog timer which is not the case with s3c series SoCs so, there is a need to have different compatible names for watchdog to handle these pmu registers access. Hence this patch removes watchdog node from Exynos5.dtsi common file and make it separate by updating existing node in Exynos5250 and adding new node to Exynos5420. This patch also makes the watchdog node enabled by default Signed-off-by: Leela Krishna Amudala <l.krishna@xxxxxxxxxxx> Reviewed-by: Tomasz Figa <t.figa@xxxxxxxxxxx> Reviewed-by: Doug Anderson <dianders@xxxxxxxxxxxx> Tested-by: Doug Anderson <dianders@xxxxxxxxxxxx> --- arch/arm/boot/dts/exynos5.dtsi | 7 ------- arch/arm/boot/dts/exynos5250.dtsi | 6 +++++- arch/arm/boot/dts/exynos5420.dtsi | 9 +++++++++ 3 files changed, 14 insertions(+), 8 deletions(-) diff --git a/arch/arm/boot/dts/exynos5.dtsi b/arch/arm/boot/dts/exynos5.dtsi index e52b038..f1fea28 100644 --- a/arch/arm/boot/dts/exynos5.dtsi +++ b/arch/arm/boot/dts/exynos5.dtsi @@ -81,13 +81,6 @@ status = "disabled"; }; - watchdog { - compatible = "samsung,s3c2410-wdt"; - reg = <0x101D0000 0x100>; - interrupts = <0 42 0>; - status = "disabled"; - }; - fimd@14400000 { compatible = "samsung,exynos5250-fimd"; interrupt-parent = <&combiner>; diff --git a/arch/arm/boot/dts/exynos5250.dtsi b/arch/arm/boot/dts/exynos5250.dtsi index 62f9e36..d440a9a 100644 --- a/arch/arm/boot/dts/exynos5250.dtsi +++ b/arch/arm/boot/dts/exynos5250.dtsi @@ -168,9 +168,13 @@ reg = <0x10040000 0x5000>; }; - watchdog { + watchdog@101D0000 { + compatible = "samsung,exynos5250-wdt"; + reg = <0x101D0000 0x100>; + interrupts = <0 42 0>; clocks = <&clock 336>; clock-names = "watchdog"; + samsung,syscon-phandle = <&pmu_system_controller>; }; g2d@10850000 { diff --git a/arch/arm/boot/dts/exynos5420.dtsi b/arch/arm/boot/dts/exynos5420.dtsi index cd47db0..167480c 100644 --- a/arch/arm/boot/dts/exynos5420.dtsi +++ b/arch/arm/boot/dts/exynos5420.dtsi @@ -407,4 +407,13 @@ compatible = "samsung,exynos5420-pmu", "syscon"; reg = <0x10040000 0x5000>; }; + + watchdog@101D0000 { + compatible = "samsung,exynos5420-wdt"; + reg = <0x101D0000 0x100>; + interrupts = <0 42 0>; + clocks = <&clock 316>; + clock-names = "watchdog"; + samsung,syscon-phandle = <&pmu_system_controller>; + }; }; -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-watchdog" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
