Merge branch 'phy-ocelot-serdes-fix-out-of-bounds-read'

Gustavo A. R. Silva says:

====================
phy: ocelot-serdes: fix out-of-bounds read

This patchset aims to fix an out-of-bounds bug in
the phy-ocelot-serdes driver.

Currently, there is an out-of-bounds read on array ctrl->phys,
once variable i reaches the maximum array size of SERDES_MAX
in the for loop.

Quentin Schulz pointed out that SERDES_MAX is a valid value to
index ctrl->phys. So, I updated SERDES_MAX to be SERDES6G_MAX + 1
in include/dt-bindings/phy/phy-ocelot-serdes.h.

Then I changed the condition in the for loop from
i <= SERDES_MAX to i < SERDES_MAX in order to
complete the fix.

The reason I'm sending this fix as series is because
checkpatch reported an error when I first tried to
integrate the whole solution into a singe patch. So,
changes to dt-bindings should be sent as a separate
patch.

Changes in v3:
- Post the series to netdev, so Dave can take it.

Changes in v2:
- Send the whole series to Kishon Vijay Abraham I, so it
can be taken into the PHY tree.
- Add Quentin's Reviewed-by to commit log in both patches.

dt-bindings: phy: Update SERDES_MAX to be SERDES_MAX + 1

SERDES_MAX is a valid value to index ctrl->phys in
drivers/phy/mscc/phy-ocelot-serdes.c. But, currently,
there is an out-of-bounds bug in the mentioned driver
when reading from ctrl->phys, because the size of
array ctrl->phys is SERDES_MAX.

Partially fix this by updating SERDES_MAX to be SERDES6G_MAX + 1.

Notice that this is the first part of the solution to
the out-of-bounds bug mentioned above. Although this
change is not dependent on any other one.

Merge branch 'mscc-ocelot-add-support-for-SerDes-muxing-configuration'

Quentin Schulz says:

====================
mscc: ocelot: add support for SerDes muxing configuration

The Ocelot switch has currently an hardcoded SerDes muxing that suits only
a particular use case. Any other board setup will fail to work.

To prepare for upcoming boards' support that do not have the same muxing,
create a PHY driver that will handle all possible cases.

A SerDes can work in SGMII, QSGMII or PCIe and is also muxed to use a
given port depending on the selected mode or board design.

The SerDes configuration is in the middle of an address space (HSIO) that
is used to configure some parts in the MAC controller driver, that is why
we need to use a syscon so that we can write to the same address space from
different drivers safely using regmap.

This breaks backward compatibility but it's fine because there's only one
board at the moment that is using what's modified in this patch series.
This will break git bisect.

Even though this patch series is about SerDes __muxing__ configuration, the
DT node is named serdes for the simple reason that I couldn't find any
mention to SerDes anywhere else from the address space handled by this
driver.

v4:
- add reviewed-by,
- format the patch series with -M for identifying renamed files,
- add parent info in DT binding of the SerDes IP,
- move to macros SERDES[16]G(X) instead of multiple SERDES[16]G_[012345]
constants,
- move to SERDES[16]G_MAX being the last VALID macro of a type, so
migrate to <= conditions instead of < when iterating,
- create a SERDES_MUX_SGMII and SERDES_MUX_QSGMII macro so the muxing
configurations are a tad more readable,
- use a bunch of unsigned int instead of int,
- return -EOPNOTSUPP for SERDES6G/PCIe until it's supported,
- simplify condition when there is an error code returned by
devm_of_phy_get,

v3:
- add Paul Burton's Acked-By on MIPS patches so that the patch series can
be merged in the net tree in its entirety,

v2:
- use a switch case for setting the phy_mode in the SerDes driver as
suggested by Andrew,
- stop replacing the value of the error pointer in the SerDes driver,
- use a dev_dbg for the deferring of the probe in the SerDes driver,
- use constants in the Device Tree to select the SerDes macro in use with
a port,
- adapt the SerDes driver to use those constants,
- add a header file in include/dt-bindings for the constants,
- fix space/tab issue,
