'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

Broadcom GISB bus Arbiter controller
|
|
|
|
Required properties:
|
|
|
|
- compatible:
|
|
"brcm,bcm7278-gisb-arb" for V7 28nm chips
|
|
"brcm,gisb-arb" or "brcm,bcm7445-gisb-arb" for other 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
|
|
- 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";
|
|
};
