[PATCH 1/5] arm64: dts: ti: k3-j721e-beagleboneai64: Fix mailbox node status

[Andrew Davis]

Mailbox nodes are now disabled by default. The BeagleBoard AI64 DT
addition went in at around the same time and must have missed that
change so the mailboxes are not re-enabled. Do that here.

[PATCH 2/5] arm64: dts: ti: k3-j721e: Remove PCIe endpoint nodes

[Andrew Davis]

These nodes are example nodes for the PCIe controller in "endpoint" mode.
By default the controller is in "root complex" mode and there is already a
DT node for the same.

Examples should go in the bindings or other documentation.

Remove this node.

[PATCH 3/5] arm64: dts: ti: k3-j721e: Enable PCIe nodes at the board level

[Andrew Davis]

PCIe nodes defined in the top-level J721e SoC dtsi files are incomplete
and will not be functional unless they are extended with a SerDes PHY.
And usually only one of the two modes can be used at a time as they
share a SerDes link.

As the PHY and mode is only known at the board integration level, these
nodes should only be enabled when provided with this information.

Disable the PCIe nodes in the dtsi files and only enable the ones that
are actually pinned out on a given board.

and may not be functional unless they are extended with a chosen interrupt
and connection to a remote processor.

As the remote processors depend on memory nodes which are only known at
the board integration level, these nodes should only be enabled when
provided with the above information.

Disable the Mailbox nodes in the dtsi files and only enable the ones that
are actually used on a given board.

[PATCH 5/5] arm64: dts: ti: k3-j721e: Enable MDIO nodes at the board level

[Andrew Davis]

MDIO nodes defined in the top-level J721e SoC dtsi files are incomplete
and will not be functional unless they are extended with a pinmux.

As the attached PHY is only known about at the board integration level,
these nodes should only be enabled when provided with this information.

Disable the MDIO nodes in the dtsi files and only enable the ones that
are actually pinned out on a given board.

I'd argue having to use a different node with a different compatible
to switch PCIe modes was not correct to begin with, it should have
been a property flag. Or even better, the modes should have been
switchable without modifying DTB at all.

Since it was chosen to put hardware configuration in DT, you'll have
to live with the problems that causes. My point it the same, examples
of how to do something do not belong in the DT files. Put the example
nodes in the documentation somewhere, then you can copy paste from that.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
