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. A third optional interrupt may be specified
for breakpoints.
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
