Thank you! [1/1] arm64: dts: ti: k3-am68-sk-base-board: Add clklb pin mux for mmc1 commit: f2a5177bb83dce16f13c9f5f8f828714e4788a8d 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. [1] https://git.kernel.org/pub/scm/linux/kernel/git/ti/linux.git

mmc1 is not functional and needs clock loopback so that it can create sampling clock from this for high speed SDIO operations. Thus, add clklb pin mux to get mmc1 working.
