1Broadcom GISB bus Arbiter controller
2
3Required properties:
4
5- compatible:
6    "brcm,gisb-arb" or "brcm,bcm7445-gisb-arb" for 28nm chips
7    "brcm,bcm7435-gisb-arb" for newer 40nm chips
8    "brcm,bcm7400-gisb-arb" for older 40nm chips and all 65nm chips
9    "brcm,bcm7038-gisb-arb" for 130nm chips
10- reg: specifies the base physical address and size of the registers
11- interrupt-parent: specifies the phandle to the parent interrupt controller
12  this arbiter gets interrupt line from
13- interrupts: specifies the two interrupts (timeout and TEA) to be used from
14  the parent interrupt controller
15
16Optional properties:
17
18- brcm,gisb-arb-master-mask: 32-bits wide bitmask used to specify which GISB
19  masters are valid at the system level
20- brcm,gisb-arb-master-names: string list of the litteral name of the GISB
21  masters. Should match the number of bits set in brcm,gisb-master-mask and
22  the order in which they appear
