[PATCH v2 00/12] ARM: bcm: Add some BCMBCA peripherals

[Linus Walleij]

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.

Changes in v2:
- Pick up Krzysztof's ACK
- Push the BCM6858 DMA block into its own simple bus.
- Fix GPIO node names and registers on BCM63138.
- Fix GPIO node names and registers on BCM63148.
- Link to v1: https://lore.kernel.org/r/20250328-bcmbca-peripherals-arm-v1-0-e4e515dc9b8c@linaro.org

[PATCH v2 01/12] ARM: dts: bcm6878: Correct UART0 IRQ number

[Linus Walleij]

According to the vendor file 6878_intr.h the UART0 has IRQ
28, not 32.

Assuming this is a copy-and-paste error.

[Linus Walleij]

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.

[PATCH v2 07/12] ARM: dts: bcm63148: Add BCMBCA peripherals

[Linus Walleij]

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 GPIO, RNG and LED and DMA blocks for the
BCM63148 based on the vendor files 63148_map_part.h and
63148_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.

[PATCH v2 10/12] ARM64: dts: bcm6856: Add BCMBCA peripherals

[Linus Walleij]

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 BCM6856 the PERF window was
too big so adjust it down to its real size (0x3000) and add
another window for PERF1 at 0xff858000.

Add the watchdog, GPIO blocks, RNG, LED, second UART and DMA
blocks for the BCM6856 based on the vendor files 6856_map_part.h
and 6856_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.

[PATCH v2 11/12] ARM64: dts: bcm6858: Add BCMBCA peripherals

[Linus Walleij]

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.

[PATCH v2 12/12] ARM64: dts: bcm63158: Add BCMBCA peripherals

[Linus Walleij]

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. On BCM63158 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 BCM63158 based on the vendor files 63158_map_part.h
and 63158_intr.h from the "bcmopen-consumer" code drop.

The DTSI file has clearly been authored for the B0 revision of
the SoC: there is an earlier A0 version, but this has
the UARTs in the legacy PERF memory space, while the B0
has opened a new peripheral window at 0xff812000 for the
three UARTs. It also has a designated AHB peripheral area
at 0xff810000 where the DMA resides, so we create new windows
for these two peripheral group reflecting the internal
structure of the B0 SoC.

This SoC has up to 256 possible GPIOs due to having 8
registers with 32 GPIOs in each available.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: base-commit 8359b1e7edc722d4b1be26aa515041a79e4224a3 not known, ignoring
 Base: attempting to guess base-commit...
 Base: tags/v6.14-rc6-274-gf4e35e5f940c (exact match)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

New warnings running 'make CHECK_DTBS=y for arch/arm/boot/dts/broadcom/' for 20250406-bcmbca-peripherals-arm-v2-0-22130836c2ed@linaro.org:

The dma controller is under the same periph bus starting from0xff800000.
You can increase the range to 0x400000 which is actual the max range.
We are using the same periph bus for dma on other v7 platforms.   We should
keep the same for v8 platfroms too IMHO.   And that's what we have for
future new chips too.
