[PATCH v2 0/6] Updates for Marvell Switch SoCs

[PATCH v2 0/6] Updates for Marvell Switch SoCs

[Chris Packham]

Shortly after I posted my last series I got access to a more recent
Marvell SDK which had some device tree support for the switch SoCs I'd
been wanting. It was still based on an older kernel but it was a huge
improvement over what came before.

Patch 1/6 is a typo I noticed after my initial series was applied.

Patch 2/6 is a bit of a cleanup. I did initially struggle with how to
access individual parts of the DFX block as well as retaining a handle on
the entire thing for the switch driver to use.

Patch 3/6 is a re-jig of the dtsi files which is needed by 5/6. This is
required because I need to use the coreclk label on a different node. It
also means I don't have to disable nodes for blocks that only exist on
the Armada-XP.

Patch 4/6, 5/6 are split from the previous versions.

Patch 6/6 is the device tree portion of a change already in clk-next.

[PATCH v3 2/6] ARM: dts: armada-xp-98dx3236: combine dfx server nodes

[Chris Packham]

Rather than having a separate node for the dfx server add a reg property
to the parent node. This give some compatibility with the Marvell
supplied SDK.

As no upstream driver currently exists for this block and support for
this SoC is still quite fresh in the kernel it should not be necessary
to retain a backwards compatible binding.

[PATCH v3 3/6] ARM: dts: Use armada-370-xp as a base for armada-xp-98dx3236

[Chris Packham]

The Marvell datasheets refer to the integrated CPU as "Armada-XP". In
reality there are a number of differences to the actual Armada-XP so
rather than including armada-xp.dtsi and disabling many of the IP
blocks. Include armada-370-xp.dtsi and add the required nodes.

How about putting this new code into a separate driver in
drivers/soc/? I don't think you need the early probing we have
here, and not that much is shared otherwise.

Not putting it there means we'll get the pci fall-back behaviour which 
will result in a incorrect rev value. Having said that no callers of 
mvebu_get_soc_id() currently care about these specific SoCs so not 
having the right rev is not an issue at the moment.

We should still care about incorrect IDs as they are shown to user space,
which could start relying on it in theory.

However, the PCI ID should only be used on chips that have a PCI
host with an ID known to be correct, so maybe we can restrict
get_soc_id_by_pci() in a way that the mvebu_pcie_of_match_table
matching does not trigger on chips on which we don't want it to.

I think we'd need to add some kind of soc-id-from-pci node to indicate 
devices where the best ID is from the PCI registers. We'd also need to 
worry about backwards compatibility etc.

For now since nothing is relying on the rev and the SoC ID is correct 
coming from the PCI registers I'm happy to sit on this patch until a 
need to get the rev arises.

[PATCH v3 6/6] ARM: dts: mvebu: Move mv98dx3236 clock bindings

[Chris Packham]

Previously the coreclk binding for the 98dx3236 SoC was inherited from
the armada-370/xp. This block is present in as much as it is possible to
read from the register location without causing any harm. However the
actual sampled at reset values are reflected in the DFX block.

Moving the binding to the DFX block enables support for different clock
strapping options in hardware.

I applied patches 2, 3 and 6 on mvebu/dt with the acked-by from Rob when
he gave it.

Patch 1 is already part of 4.11-rc1.

For patch 4 and 5 I understand that either we don't need it or it should
be a updated version so I skipped them.

Thanks,

Gregory

That's correct, thanks.

[PATCH v2 0/6] Updates for Marvell Switch SoCs

[Chris Packham]

Shortly after I posted my last series I got access to a more recent
Marvell SDK which had some device tree support for the switch SoCs I'd
been wanting. It was still based on an older kernel but it was a huge
improvement over what came before.

Patch 1/6 is a typo I noticed after my initial series was applied.

Patch 2/6 is a bit of a cleanup. I did initially struggle with how to
access individual parts of the DFX block as well as retaining a handle on
the entire thing for the switch driver to use.

Patch 3/6 is a re-jig of the dtsi files which is needed by 5/6. This is
required because I need to use the coreclk label on a different node. It
also means I don't have to disable nodes for blocks that only exist on
the Armada-XP.

Patch 4/6, 5/6 and 6/6 are ported from the Marvell Linux kernel. I've tested
them on the hardware I have access to and things look pretty good.
