Add a device node for the System Controller. Hook up the Cortex-A7 CPU cores and the Cortex-A7 L2 cache/SCU to their respective PM Domains.
Signed-off-by: Geert Uytterhoeven <geert+rene...@glider.be> --- v5: - Remove "power-domains" property again from the sysc node, as the System Controller itself is not part of the Clock Domain, v4: - Add "power-domains" property to the sysc node, to refer to the SoC's Clock Domain, v3: - Drop power area hiearchy from DT, - Switch to "#power-domain-cells = <1>", - Drop fallback compatibility strings, v2: - Change one-line summary prefix to match current arm-soc practices, - Update compatible values. --- arch/arm/boot/dts/r8a7794.dtsi | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/arch/arm/boot/dts/r8a7794.dtsi b/arch/arm/boot/dts/r8a7794.dtsi index 29a0a001f1b21a9e..99c41c9099b0c233 100644 --- a/arch/arm/boot/dts/r8a7794.dtsi +++ b/arch/arm/boot/dts/r8a7794.dtsi @@ -12,6 +12,7 @@ #include <dt-bindings/clock/r8a7794-clock.h> #include <dt-bindings/interrupt-controller/arm-gic.h> #include <dt-bindings/interrupt-controller/irq.h> +#include <dt-bindings/power/r8a7794-sysc.h> / { compatible = "renesas,r8a7794"; @@ -42,6 +43,7 @@ compatible = "arm,cortex-a7"; reg = <0>; clock-frequency = <1000000000>; + power-domains = <&sysc R8A7794_PD_CA7_CPU0>; next-level-cache = <&L2_CA7>; }; @@ -50,12 +52,14 @@ compatible = "arm,cortex-a7"; reg = <1>; clock-frequency = <1000000000>; + power-domains = <&sysc R8A7794_PD_CA7_CPU1>; next-level-cache = <&L2_CA7>; }; }; L2_CA7: cache-controller@1 { compatible = "cache"; + power-domains = <&sysc R8A7794_PD_CA7_SCU>; cache-unified; cache-level = <2>; }; @@ -1244,6 +1248,12 @@ }; }; + sysc: system-controller@e6180000 { + compatible = "renesas,r8a7794-sysc"; + reg = <0 0xe6180000 0 0x0200>; + #power-domain-cells = <1>; + }; + ipmmu_sy0: mmu@e6280000 { compatible = "renesas,ipmmu-r8a7794", "renesas,ipmmu-vmsa"; reg = <0 0xe6280000 0 0x1000>; -- 1.9.1
