Out of the brcmstb SoCs that I know, BCM3390 has the largest numbers of GPIOs, with its - 320 "peripheral" GPIOs - 5*32 = 160 UPG GPIOs (counting unused lines, which do get counted) - 2*32 = 64 UPG AON GPIOs (counting unused lines) Total: 544 I suspect that the upper limit will only need to be higher in the future, so set it to 1024.
