[PATCH 00/10] AM62x Disable Incomplete DT Nodes

[PATCH 00/10] AM62x Disable Incomplete DT Nodes

[Andrew Davis]

Hello all,

Same story as for AM64x[0], this time for AM62x. If there
are no objections here then the J7x platforms are next.

Thanks,
Andrew

[PATCH 01/10] arm64: dts: ti: k3-am62: Enable UART nodes at the board level

[Andrew Davis]

UART nodes defined in the top-level AM62x SoC dtsi files are incomplete
and will not be functional unless they are extended with pinmux
information.

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

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

[PATCH 05/10] arm64: dts: ti: k3-am62: Enable ECAP nodes at the board level

[Andrew Davis]

ECAP nodes defined in the top-level AM62x SoC dtsi files are incomplete
and will not be functional unless they are extended with pinmux
information. (These and the EPWM nodes could be used to trigger internal
actions but they are not used like that currently)

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

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

[PATCH 06/10] arm64: dts: ti: k3-am62: MDIO pinmux should belong to the MDIO node

[Andrew Davis]

Although usually integrated as a child of an Ethernet controller, MDIO
IP has an independent pinout. This pinout should be controlled by
the MDIO node (so if it was to be disabled for instance, the pinmux
state would reflect that).

Move the MDIO pins pinmux to the MIDO nodes.

[PATCH 07/10] arm64: dts: ti: k3-am62: Enable MDIO nodes at the board level

[Andrew Davis]

MDIO nodes defined in the top-level AM62x 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.

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.
