SDHCI nodes defined in the top-level AM65 SoC dtsi files are incomplete
and will not be functional unless they are extended.

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

Disable the SDHCI 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.
