Will do for v3. I did actually include a changelog in the individual
patches but I can collate that here.
clk: mvebu: support for 98DX3236 SoC
- Update devicetree binding documentation for new compatible string
arm: mvebu: support for SMP on 98DX3336 SoC
- Document new enable-method value
- Correct some references from 98DX4521 to 98DX3236
pinctrl: mvebu: pinctrl driver for 98DX3236 SoC
- include sdio support for the 98DX4251
arm: mvebu: Add device tree for 98DX3236 SoCs
- Update devicetree binding documentation to reflect that 98DX3336 and
984251 are supersets of 98DX3236.
- disable crypto block
- disable sdio for 98DX3236, enable for 98DX4251
arm: mvebu: Add device tree for db-dxbc2 and db-xc3-24g4xg boards
- None

Sebastian? Sorry for the ignorance. I don't have the patch to reply to inline, but: - In the driver MPP_MODE2, spi0 there is a typo "csk" instead of "sck". - MPP_MODE5 binding "dev","bootcs" and driver "dev","bootcs0" differ. - MPP_MODE6 binding "gpio" and driver "gpo" differ. - MPP_MODE17 binding "dev","clk" and driver "dev","clkout" differ. - MPP_MODE19 binding mentiones "dev","rb" but driver does not. - MPP_MODE20 binding "gpio" and driver "gpo" differ. - MPP_MODE20 binding "dev","we" and driver "dev","we0" differ. - MPP_MODE21 through MPP_MODE30 binding "gpio" and driver "gpo" differ. - remove spaces before "0, 0" in mv98dx3236_mpp_gpio_ranges.

One point on "gpio" vs "gpo" this one isn't a typo. Some of these pins can be driven as outputs but can't be used as inputs. From a pinctrl driver point of view there is no difference but I did want to convey that from a system design point of view if you really need something to be an input you shouldn't use one of these pins. This is also noted in the datasheets so it doesn't necessarily need repeating. If you still want me to use "gpio" in the code and binding I'm happy to do so.

The 98DX3236, 98DX3336, 98DX4521 and variants have a different TCLK from
the Armada XP (200MHz vs 250MHz). The CPU core clock is fixed at 800MHz.
The clock gating options are a subset of those on the Armada XP.
The core clock divider is different to the Armada XP also.

Changes in v2:
- Update devicetree binding documentation for new compatible string
Changes in v3:
- Add 98dx3236 support to mvebu/clk-corediv.c rather than creating a new
driver.
- Document mv98dx3236-corediv-clock binding

The 98DX3236, 98DX3336 and 98DX4251 are a set of switch ASICs with
integrated CPUs. They CPU block is common within these product lines and
(as far as I can tell/have been told) is based on the Armada XP. There
are a few differences due to the fact they have to squeeze the CPU into
the same package as the switch.
Chris Packham (4):

| Subject | [PATCHv3 2/5] arm: mvebu: support for SMP on 98DX3336 SoC |
| Message-ID | <sWuau-4AF-41@gated-at.bofh.it> |
| In reply to | #1552517 |
Compared to the armada-xp the 98DX3336 uses different registers to set
the boot address for the secondary CPU so a new enable-method is needed.
This will only work if the machine definition doesn't define an overall
smp_ops because there is not currently a way of overriding this from the
device tree if it is set in the machine definition.
Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz>
---
Changes in v2:
- Document new enable-method value
- Correct some references from 98DX4521 to 98DX3236
Changes in v3:
- Simplify mv98dx3236_resume_init by using of_io_request_and_map()

Doesn't the core already print something when bringing up CPUs?

Is there any reason we can't just look for this node from the
smp_ops and map it if it isn't mapped yet? Seems simpler than a
whole new file and initcall.

Doesn't of_io_request_and_map() spit out an error on failure
already?

This could be done before the if statement and then the duplicate

Should be PTR_ERR(base)?

Copied from armada_xp_boot_secondary but that's no reason to keep it.

That's at least 2 votes for rolling it into platsmp.c. The amount of
code has been significantly reduced so I think I will do it for v4.

Not that I can see. But as has been previously mentioned a CPU failing
to come online is reasonably obvious already.

Yes. I decided to add the local variable at the last minute.

| Subject | [PATCHv3 4/5] arm: mvebu: Add device tree for 98DX3236 SoCs |
| Message-ID | <sWuka-4DR-7@gated-at.bofh.it> |
| In reply to | #1552517 |
The Marvell 98DX3236, 98DX3336, 98DX4521 and variants are switch ASICs
with integrated CPUs. They are similar to the Armada XP SoCs but have
different I/O interfaces.
Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz>
---
Changes in v2:
- Update devicetree binding documentation to reflect that 98DX3336 and
984251 are supersets of 98DX3236.
- disable crypto block
- disable sdio for 98DX3236, enable for 98DX4251
Changes in v3:
- fix typo 4521 -> 4251
- document prestera bindings
- rework corediv-clock binding
- add label to packet processor node
- add new compativle string for DFX server
