[PATCH] arm64: dts: ti: k3-am62a7-phyboard-lyra-rdk: Update ethernet internal delay
Posted by Nathan Morrisson 1 month, 3 weeks ago
Update the RGMII delay to 2.5ns to improve performance. We use an
additional mapper board for the am62a7 phyBOARD Lyra which makes this
delay necessary.

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!

[1/1] arm64: dts: ti: k3-am62a7-phyboard-lyra-rdk: Update ethernet internal delay
      commit: e6c01aeb220274b1ce7b19d1b8fdfe433984cbd2

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.
