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(+)
