[PATCH v6 0/5] Enable eQEP DT support for Sitara K3 platforms

[PATCH v6 0/5] Enable eQEP DT support for Sitara K3 platforms

[Judith Mendez]

Git rebased the series since due to merge conflicts, part of the
series was not merged. Also dropped the patches that were already
merged.

This patch series adds eQEP DT nodes for K3 Sitara devices:
- AM62x
- AM62ax
- AM62px
- AM64x

Changes since v5:
- Drop patch 1/8, 2/8, 8/8 since they have been merged

There are 3 instances of eQEP on AM64x. Only EQEP0 signals
can be routed to the user expansion so enable only EQEP0
in k3-am642-sk.dts.

I recall last time these needed to go via the TI SoC/arm64 tree [^1]. Is
that still the case, or do you want me to pick these up now via the
Counter tree?

Yes, I will queue this up now to 6.12-rc1 is out. Feel free to ignore

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.
