Acked-by: Arnd Bergmann Signed-off-by: Florian Fainelli --- Changes in v3: - renamed UART nodes from uart to serial to follow ePAPR - added Arnd's Acked-by tag Changes in v2: - removed buses 'reg' properties since they are unused - align buses 'ranges' properties on a nicer boundary - moved mpcore peripherals one level higher in the axi bus - added uart nodes since we have a driver for it (bcm63xx_uart) arch/arm/boot/dts/bcm63138.dtsi | 134 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 134 insertions(+) create mode 100644 arch/arm/boot/dts/bcm63138.dtsi diff --git a/arch/arm/boot/dts/bcm63138.dtsi b/arch/arm/boot/dts/bcm63138.dtsi new file mode 100644 index 000000000000..f3bb2dd6269e --- /dev/null +++ b/arch/arm/boot/dts/bcm63138.dtsi @@ -0,0 +1,134 @@ +/* + * Broadcom BCM63138 DSL SoCs Device Tree + */ + +#include +#include + +#include "skeleton.dtsi" + +/ { + compatible = "brcm,bcm63138"; + model = "Broadcom BCM63138 DSL SoC"; + interrupt-parent = <&gic>; + + aliases { + uart0 = &serial0; + uart1 = &serial1; + }; + + cpus { + #address-cells = <1>; + #size-cells = <0>; + + cpu@0 { + device_type = "cpu"; + compatible = "arm,cortex-a9"; + next-level-cache = <&L2>; + reg = <0>; + }; + + cpu@1 { + device_type = "cpu"; + compatible = "arm,cortex-a9"; + next-level-cache = <&L2>; + reg = <1>; + }; + }; + + clocks { + #address-cells = <1>; + #size-cells = <0>; + + arm_timer_clk: arm_timer_clk { + #clock-cells = <0>; + compatible = "fixed-clock"; + clock-frequency = <500000000>; + }; + + periph_clk: periph_clk { + #clock-cells = <0>; + compatible = "fixed-clock"; + clock-frequency = <50000000>; + clock-output-names = "periph"; + }; + }; + + /* ARM bus */ + axi@80000000 { + compatible = "simple-bus"; + ranges = <0 0x80000000 0x784000>; + #address-cells = <1>; + #size-cells = <1>; + + L2: cache-controller@1d000 { + compatible = "arm,pl310-cache"; + reg = <0x1d000 0x1000>; + cache-unified; + cache-level = <2>; + cache-sets = <16>; + cache-size = <0x80000>; + interrupts = ; + }; + + scu: scu@1e000 { + compatible = "arm,cortex-a9-scu"; + reg = <0x1e000 0x100>; + }; + + gic: interrupt-controller@1e100 { + compatible = "arm,cortex-a9-gic"; + reg = <0x1f000 0x1000 + 0x1e100 0x100>; + #interrupt-cells = <3>; + #address-cells = <0>; + interrupt-controller; + }; + + global_timer: timer@1e200 { + compatible = "arm,cortex-a9-global-timer"; + reg = <0x1e200 0x20>; + interrupts = ; + clocks = <&arm_timer_clk>; + }; + + local_timer: local-timer@1e600 { + compatible = "arm,cortex-a9-twd-timer"; + reg = <0x1e600 0x20>; + interrupts = ; + clocks = <&arm_timer_clk>; + }; + + twd_watchdog: watchdog@1e620 { + compatible = "arm,cortex-a9-twd-wdt"; + reg = <0x1e620 0x20>; + interupts = ; + }; + }; + + /* Legacy UBUS base */ + ubus@fffe8000 { + compatible = "simple-bus"; + #address-cells = <1>; + #size-cells = <1>; + ranges = <0 0xfffe8000 0x8100>; + + serial0: serial@600 { + compatible = "brcm,bcm6345-uart"; + reg = <0x600 0x1b>; + interrupts = ; + clocks = <&periph_clk>; + clock-names = "periph"; + status = "disabled"; + }; + + serial1: serial@620 { + compatible = "brcm,bcm6345-uart"; + reg = <0x620 0x1b>; + interrupts = ; + clocks = <&periph_clk>; + clock-names = "periph"; + status = "disabled"; + }; + }; +}; -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
