| Broadcom GISB bus Arbiter controller |
| |
| Required properties: |
| |
| - compatible: |
| "brcm,gisb-arb" or "brcm,bcm7445-gisb-arb" for 28nm chips |
| "brcm,bcm7435-gisb-arb" for newer 40nm chips |
| "brcm,bcm7400-gisb-arb" for older 40nm chips and all 65nm chips |
| "brcm,bcm7038-gisb-arb" for 130nm chips |
| - reg: specifies the base physical address and size of the registers |
| - interrupt-parent: specifies the phandle to the parent interrupt controller |
| this arbiter gets interrupt line from |
| - interrupts: specifies the two interrupts (timeout and TEA) to be used from |
| the parent interrupt controller |
| |
| Optional properties: |
| |
| - brcm,gisb-arb-master-mask: 32-bits wide bitmask used to specify which GISB |
| masters are valid at the system level |
| - brcm,gisb-arb-master-names: string list of the litteral name of the GISB |
| masters. Should match the number of bits set in brcm,gisb-master-mask and |
| the order in which they appear |
| |
| Example: |
| |
| gisb-arb@f0400000 { |
| compatible = "brcm,gisb-arb"; |
| reg = <0xf0400000 0x800>; |
| interrupts = <0>, <2>; |
| interrupt-parent = <&sun_l2_intc>; |
| |
| brcm,gisb-arb-master-mask = <0x7>; |
| brcm,gisb-arb-master-names = "bsp_0", "scpu_0", "cpu_0"; |
| }; |
