Thank you! [1/1] arm64: dts: ti: k3-am62x-sk-common: Add bootph-all for I2C1 instance pinmux commit: 175133a32b48a092363828ce3041a0adaab01ffc 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

I2C1 controller controls io-expander which provides power to voltage regulator vdd_mmc1 for MMC SD using a gpio line. Add bootph-all to the pinmux node for this instance, as this is used during SPL stage too by the bootloader while using SD boot mode as without this the SD boot mode fails with below error when using this device-tree in u-boot: "Timed out in wait_for_event: status=0000 Check if pads/pull-ups of bus are properly configured Timed out in wait_for_event: status=0000 Check if pads/pull-ups of bus are properly configured " Signed-off-by: Devarsh Thakkar <devarsht@ti.com> --- arch/arm64/boot/dts/ti/k3-am62x-sk-common.dtsi | 1 + 1 file changed, 1 insertion(+)
