Subject: [PATCH v3] arm64: dts: ti: k3-j721e-main: Remove ti,strobe-sel property

According to latest errata of J721e [1], (i2024) 'MMCSD: Peripherals
Do Not Support HS400' which applies to MMCSD0 subsystem. Speed modes
supported has been already updated in commit eb8f6194e807 ("arm64: dts: ti: k3-j721e-main: Update the speed modes supported and their itap delay values for MMCSD subsystems")
but it missed dropping 'ti,strobe-sel' property which is only required
by HS400 speed mode.

Thus, drop 'ti,strobe-sel' property from kernel dtsi for J721e SoC.

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

[1/1] arm64: dts: ti: k3-j721e-main: Remove ti,strobe-sel property
commit: 4f4b30a777d3e61603119297965343a37be36435

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.
