Thank you! [1/1] arm64: dts: ti: k3-am654-base-board: Add I2C I/O expander commit: 2f40c6df3dcc1341afd99cd1a4de035f807c8a03 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 -- Vignesh

AM654 baseboard has two TCA9554 I/O expander on the WKUP_I2C0 bus. The expander at address 0x38 is used to detect daughter cards. Add a node for this I/O expander. Signed-off-by: Ravi Gunasekaran <r-gunasekaran@ti.com> --- Changes from v1: --------------- * Moved the expander node @38 to appear before the one at address 39. * Removed the label pca9554_1 for the node as it is not used. v1: https://lore.kernel.org/all/20230919050340.16156-1-r-gunasekaran@ti.com/ arch/arm64/boot/dts/ti/k3-am654-base-board.dts | 7 +++++++ 1 file changed, 7 insertions(+) base-commit: dfa449a58323de195773cf928d99db4130702bf7
