[PATCH v4 00/15] MMC pinmux configuration fixes

[PATCH v4 00/15] MMC pinmux configuration fixes

[Judith Mendez]

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]

[PATCH v4 01/15] arm64: dts: ti: k3-am62a: Fix MMC0_CLK register address

[Judith Mendez]

MMC0_CLKLB and MMC0_CLK have incorrectly swapped register addresses
as per datasheet [0]. Set the correct MMC0_CLK address and drop the
unneeded MMC0_CLKLB pin configuration.

Shouldn't be MMC0_CLK be o/p, instead of  PIN_INPUT

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 02/15] arm64: dts: ti: k3-am62l-evm: Remove unnecessary internal pullups for MMC0

[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

[PATCH v4 13/15] arm64: dts: ti: k3-am625-var-som-symphony: Set SD clock pins as OUTPUT

[Judith Mendez]

MMC clock pins must be configured as OUTPUT-only per TRM [0] with
receiver disabled (RXACTIVE bit = 0). Change MMC CLK pins from
PIN_INPUT to PIN_OUTPUT to match documentation.

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.
