v4 cover MMC pinmux configuration fixes

This series fixes MMC pin input/output and pullup/pulldown settings across AM62*, AM62AX, and AM62LX boards.

All patches have been tested on their appropriate SK & EVM boards. BeaglePlay and Pocketbeagle boards have also been tested.

Changes since v3:
- Include PIN_OUTPUT fixes for missing third-party boards as per Sashiko review [0]
- Split out squashed patches into separate commits as per Nishanth's review [1]

Yes it should, and it is in the same series as you pointed out. This current patch only fixes register address as per commit description. (:

PATCH v4 2/15 arm64: dts: ti: k3-am62l-evm: Remove unnecessary internal pullups for MMC0

In reply to Judith Mendez

AM62L EVM has external pullups on MMC0 CMD and D0 pins [0]. Remove internal pullups considering:
- Internal pullups are not required, without internal pullups, RDAT and RCMD values of 47K are within spec
- having both pullups (stronger pull) results in unnecessary power consumption

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.
