btw, "The MMCSD peripherals do not support the Multimedia Card HS400
mode." is the exact text of the erratum. Even though it applies to
instance 0. I think minor rewording will probably help people from
running to search for which specific instances.
updated in commit eb8f6194e807 ("arm64: dts: ti: k3-j721e-main: Update the speed modes supported and their itap delay values for MMCSD subsystems")
Please format this correctly.
Commit Title was large ( > 72 chars ) so kept in same line.
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.
