1 Broadcom GISB bus Arbiter controller
6 "brcm,bcm7278-gisb-arb" for V7 28nm chips
7 "brcm,gisb-arb" or "brcm,bcm7445-gisb-arb" for other 28nm chips
8 "brcm,bcm7435-gisb-arb" for newer 40nm chips
9 "brcm,bcm7400-gisb-arb" for older 40nm chips and all 65nm chips
10 "brcm,bcm7038-gisb-arb" for 130nm chips
11 - reg: specifies the base physical address and size of the registers
12 - interrupt-parent: specifies the phandle to the parent interrupt controller
13 this arbiter gets interrupt line from
14 - interrupts: specifies the two interrupts (timeout and TEA) to be used from
15 the parent interrupt controller
19 - brcm,gisb-arb-master-mask: 32-bits wide bitmask used to specify which GISB
20 masters are valid at the system level
21 - brcm,gisb-arb-master-names: string list of the litteral name of the GISB
22 masters. Should match the number of bits set in brcm,gisb-master-mask and
23 the order in which they appear
