Verdin AM62 board does not have external pullups on eMMC DAT1-DAT7 pins.
Enable internal pullups on DAT1-DAT7 considering:

 - without a host-side pullup, these lines rely solely on the eMMC
   device's internal pullup (R_int, 10kohm-150kohm per JEDEC), which may
   exceed the recommended 50kohm max for 1.8V VCCQ
 - JEDEC JESD84-B51 Table 200 requires host-side pullups (R_DAT,
   10kohm-100kohm) on all data lines to prevent bus floating

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

[1/1] arm64: dts: ti: am62-verdin: Enable pullup for eMMC data pins
      commit: d5325810814ee995debfa0b6c4a22e0391598bef

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.
