> Subject: [PATCH v3 06/12] ARM: dts: bcm63138: 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.
>
> Extend the peripheral interrupt window to 0x10000 as it need
> to fit the DMA block.
>
> Add the GPIO, RNG and LED and DMA blocks for the
> BCM63138 based on the vendor files 63138_map_part.h and
> 63138_intr.h from the "bcmopen-consumer" code drop.
>
> This SoC has up to 160 possible GPIOs due to having 5
> registers with 32 GPIOs in each available.
