From 8d7ccceae0e118cc264afddc8ca5affda22717a5 Mon Sep 17 00:00:00 2001 From: Leela Krishna Amudala Date: Sun, 16 Feb 2014 01:58:29 +0900 Subject: ARM: dts: update watchdog device nodes for exynos5250 and exynos5420 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 Reviewed-by: Tomasz Figa Reviewed-by: Doug Anderson Tested-by: Doug Anderson Acked-by: Guenter Roeck Signed-off-by: Kukjin Kim --- arch/arm/boot/dts/exynos5420.dtsi | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/arch/arm/boot/dts/exynos5420.dtsi b/arch/arm/boot/dts/exynos5420.dtsi index 078b6ffd0c7..9c834cc2ad7 100644 --- a/arch/arm/boot/dts/exynos5420.dtsi +++ b/arch/arm/boot/dts/exynos5420.dtsi @@ -657,4 +657,13 @@ clocks = <&clock 319>, <&clock 318>; clock-names = "tmu_apbif", "tmu_triminfo_apbif"; }; + + 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>; + }; }; -- cgit v1.2.3
