[PATCH 00/12] ARM: bcm: Add some BCMBCA peripherals

[Linus Walleij <linus.walleij@linaro.org>]

This adds a bunch peripherals to the Broadcom BRCMBCA
SoC:s that I happened to find documentation for in some
vendor header files.

It started when I added a bunch of peripherals for the
BCM6846, and this included really helpful peripherals
such as the PL081 DMA, for which I think the most common
usecase is to be used as a memcpy engine to offload
transfer of blocks from NAND flash to/from the NAND
flash controller (at least this is how the STMicro
FSMC controller was using it).

So I took a sweep and added all the stuff that has
bindings to:

ARM:
- BCM6846
- BCM6855
- BCM6878
- BCM63138
- BCM63148
- BCM63178

ARM64:
- BCM4908
- BCM6856
- BCM6858
- BCM63158

There are several "holes" in this SoC list, I simply
just fixed those that I happened to run into documentation
for.

Unfortunately while very similar, some IP blocks vary
slightly in version, the GPIO block is differently
integrated on different systems, and the interrupt assignments
are completely different, so it's safest to add these to each
DTSI individually.

I add the interrupt binding for the RNG block in the
process as this exists even if Linux isn't using the
IRQ, and I put the RNG and DMA engines as default-enabled
because they are not routed to the outside and should
"just work" so why not.

I did a rogue patch adding some stuff to BCM6756 based
on guessed but eventually dropped it. If someone has
docs for this SoC I can add it.
