> Subject: [PATCH v2 11/12] ARM64: dts: bcm6858: 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. ARM64 SoCs have additional
> peripherals at 0xff858000. On BCM6858 the PERF window was
> too big so adjust it down to its real size (0x3000).
>
> Add the watchdog, GPIO blocks, RNG, LED, second UART and DMA
> blocks for the BCM6858 based on the vendor files 6858_map_part.h
> and 6858_intr.h from the "bcmopen-consumer" code drop.
>
> Curiously, on the BCM6858, the PL081 DMA block is separate
> from the two peripheral groups PERF and PERF1, so we put it
> in its own bus in the device tree to translate the fourcell
> addresses.
>
> This SoC has up to 256 possible GPIOs due to having 8
> registers with 32 GPIOs in each available.
