From 1d28762096ff79c272d9e3c08320910fbdbd0ee0 Mon Sep 17 00:00:00 2001 From: Leela Krishna Amudala Date: Sun, 16 Feb 2014 01:58:29 +0900 Subject: [PATCH] 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/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 258dca441f36..79d0608d6dcc 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 a55a5e872efa..a76a1895b87d 100644 --- a/arch/arm/boot/dts/exynos5250.dtsi +++ b/arch/arm/boot/dts/exynos5250.dtsi @@ -172,9 +172,13 @@ 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 078b6ffd0c7f..9c834cc2ad79 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>; + }; }; -- 2.20.1
