> Subject: [PATCH v2 05/12] ARM: dts: bcm6878: Add BCMBCA peripherals
>
> All the BCMBCA SoCs share a set of peripherals at 0xff800000,
> albeit at slightly varying memory locations on the bus and
> with varying IRQ assignments.
>
> Add the first and second watchdog, GPIO, RNG, LED and
> DMA blocks for the BCM6878 based on the vendor files
> 6878_map_part.h and 6878_intr.h from the "bcmopen-consumer"
> code drop.
>
> This SoC has up to 256 possible GPIOs due to having 8
> registers with 32 GPIOs in each available.
