[PATCH v5 net-next 00/13] add support for the the vsc7512 internal copper phys

[Colin Foster]

This patch series is a continuation to add support for the VSC7512:
https://patchwork.kernel.org/project/netdevbpf/list/?series=674168&state=*

That series added the framework and initial functionality for the
VSC7512 chip. Several of these patches grew during the initial
development of the framework, which is why v1 will include changelogs.
It was during v9 of that original MFD patch set that these were dropped.

With that out of the way, the VSC7512 is mainly a subset of the VSC7514
chip. The 7512 lacks an internal MIPS processor, but otherwise many of
the register definitions are identical. That is why several of these
patches are simply to expose common resources from
drivers/net/ethernet/mscc/*.

This patch only adds support for the first four ports (swp0-swp3). The
remaining ports require more significant changes to the felix driver,
and will be handled in the future.


***
Note on V5: This driver triggers a bug in phy_device.c. A fix has been
sent to 'net': https://lkml.org/lkml/2023/1/27/1105
***

v5
    * Documentation overhauled to use
      /schemas/net/mscc,vsc7514-switch.yaml instead of
      /schemas/net/dsa/mscc,ocelot.yaml
    * Two patches were applied elsewhere, so have been dropped:
      "net: dsa: felix: populate mac_capabilities for all ports" and
      "dt-bindings: mfd: ocelot: remove spi-max-frequency from required
       properties"
    * stats_layout changes are no longer necessary, so the patch
      "net: mscc: ocelot: expose stats layout definition to be used by
       other drivers" has been dropped
    * Common naming macros has been dropped:
      "mfd: ocelot: add shared resource names for switch functionality".
      This changed patches 12-13 slightly.
    * Patch 12 had some small changes due to the rebase - more info there

v4
    * Update documentation to include all ports / modes (patch 15)
    * Fix dt_bindings_check warnings (patch 13, 14, 15)
    * Utilize new "resource_names" reference (patch 9, 12, 16)
    * Drop unnecessary #undef REG patch in pinctl: ocelot
    * Utilize standard MFD resource addition (patch 17)
    * Utilize shared vsc7514_regmap (new patch 6)
    * Allow forward-compatibility on fully-defined device trees
      (patch 10,14)

v3
    * Fix allmodconfig build (patch 8)
    * Change documentation wording (patch 12)
    * Import module namespace (patch 13)
    * Fix array initializer (patch 13)

v2
    * Utilize common ocelot_reset routine (new patch 5, modified patch 13)
    * Change init_regmap() routine to be string-based (new patch 8)
    * Split patches where necessary (patches 9 and 14)
    * Add documentation (patch 12) and MAINTAINERS (patch 13)
    * Upgrade to PATCH status

v1 (from RFC v8 suggested above):
    * Utilize the MFD framework for creating regmaps, as well as
      dev_get_regmap() (patches 7 and 8 of this series)

[PATCH v5 net-next 02/13] net: mscc: ocelot: expose regfield definition to be used by other drivers

[Colin Foster]

The ocelot_regfields struct is common between several different chips, some
of which can only be controlled externally. Export this structure so it
doesn't have to be duplicated in these other drivers.

Rename the structure as well, to follow the conventions of other shared
resources.

    * Add Reviewed tag

v1 from previous RFC:
    * Remove GCB_SOFT_RST_SWC_RST entry from the regfields struct - it
      isn't used.
    * Export the vsc7514_regfields symbol so it can be used as a module.

[PATCH v5 net-next 03/13] net: mscc: ocelot: expose vcap_props structure

[Colin Foster]

The vcap_props structure is common to other devices, specifically the
VSC7512 chip that can only be controlled externally. Export this structure
so it doesn't need to be recreated.

[Colin Foster]

The define FELIX_MAC_QUIRKS was used directly in the felix.c shared driver.
Other devices (VSC7512 for example) don't require the same quirks, so they
need to be configured on a per-device basis.

[PATCH v5 net-next 07/13] net: dsa: felix: add support for MFD configurations

[Colin Foster]

The architecture around the VSC7512 differs from existing felix drivers. In
order to add support for all the chip's features (pinctrl, MDIO, gpio) the
device had to be laid out as a multi-function device (MFD).

One difference between an MFD and a standard platform device is that the
regmaps are allocated to the parent device before the child devices are
probed. As such, there is no need for felix to initialize new regmaps in
these configurations, they can simply be requested from the parent device.

Add support for MFD configurations by performing this request from the
parent device.

[PATCH v5 net-next 08/13] net: dsa: felix: add functionality when not all ports are supported

[Colin Foster]

When the Felix driver would probe the ports and verify functionality, it
would fail if it hit single port mode that wasn't supported by the driver.

The initial case for the VSC7512 driver will have physical ports that
exist, but aren't supported by the driver implementation. Add the
OCELOT_PORT_MODE_NONE macro to handle this scenario, and allow the Felix
driver to continue with all the ports that are currently functional.

[PATCH v5 net-next 09/13] mfd: ocelot: prepend resource size macros to be 32-bit

[Colin Foster]

The *_RES_SIZE macros are initally <= 0x100. Future resource sizes will be
upwards of 0x200000 in size.

To keep things clean, fully align the RES_SIZE macros to 32-bit to do
nothing more than make the code more consistent.

[PATCH v5 net-next 10/13] dt-bindings: net: mscc,vsc7514-switch: add dsa binding for the vsc7512

[Colin Foster]

The VSC7511, VSC7512, VSC7513 and VSC7514 all have the ability to be
controlled either internally by a memory-mapped CPU, or externally via
interfaces like SPI and PCIe. The internal CPU of the VSC7511 and 7512
don't have the resources to run Linux, so must be controlled via these
external interfaces in a DSA configuration.

Add mscc,vsc7512-switch compatible string to indicate that the chips are
being controlled externally in a DSA configuration.

[PATCH v5 net-next 13/13] mfd: ocelot: add external ocelot switch control

[Colin Foster]

Utilize the existing ocelot MFD interface to add switch functionality to
the Microsemi VSC7512 chip.

Signed-off-by: Colin Foster <colin.foster@in-advantage.com>
Acked-for-MFD-by: Lee Jones <lee@kernel.org>
---

v5
    * Add Acked-for-MFD Lee tag
    * Remove OCELOT_REG_NAME_ macros

v4
    * Integrate a different patch, so now this one
      - Adds the resources during this patch. Previouisly this
        was done in a separate patch
      - Utilize the standard {,num_}resources initializer

v3
    * No change

v2
    * New patch, broken out from a previous one

A minor nitpick after this is merged: please clean up and unexport stuff
from include/soc/mscc/vsc7514_regs.h which was added with your previous
approaches and then we steered mid-way.

Congratulations!

Please don't do that.  The commits do not have proper Acked-by tags.

The plan is to merge these via MFD and send out a pull-request to an
immutable branch.  However, if you're prepared to convert all of the:

  Acked-for-MFD-by: Lee Jones <lee@kernel.org>

to

  Acked-by: Lee Jones <lee@kernel.org>

... and send out a pull request to a succinct (only these patches) and
immutable branch then that is also an acceptable solution.

Please let me know what works best for you.

Thanks.

Sorry, I must have been blind yesterday because I definitely double
checked this doesn't touch mfd code. And it does :/

The patches should not be sent for net-next if they are not supposed 
to be applied directly. Or at the very least says something about
merging in the cover letter!

Sorry for messing up again. Stable branch would obviously had been best.
Do we have to take action now, or can we just wait for the trees to
converge during the merge window?

My apologies. I wasn't sure how these cross-tree syncs would be done
(and I recognize Lee even asked during a previous submission.) I'll be
more verbose in cover letters moving forward, should I ever be
submitting against multiple trees like this.

Russell explained to me (off-list) that the net-next branch is immutable
and the only way to fix this would be to revert the whole set.

Let's not go to that much trouble this time.

It does mean that I cannot take any more commits on the affected files,
but that shouldn't be a big deal seeing how far into the release cycle
we are.

No real harm done.
