BeagleBoard.org BeagleY-AI is an easy to use, affordable open source
hardware single board computer based on the Texas Instruments AM67A,
which features a quad-core 64-bit Arm CPU subsystem, 2 general-purpose
digital-signal-processors (DSP) and matrix-multiply-accelerators (MMA),
GPU, vision and deep learning accelerators, and multiple Arm Cortex-R5
cores for low-power, low-latency GPIO control.

Changes since v1:
 - fixed incorrect vdd-3v3-sd-pins-default name
 - updated hdmi VDD_1V2 regulator for production pcb
 - switched device tree name from k3-j722s-beagley-ai to k3-am67a-beagley-ai
 - removed cpsw_port2 node
 - enable UHS support for MMCSD

you will need bootph-all; here.

I suggest using GPIO mode 7 here. (and see below):
		J722S_IOPAD(0x0240, PIN_INPUT, 7) /* (B24) MMC1_SDCD */

you can optionally enable debounce as well if that is useful.

Also add:
cd-gpios = <&main_gpio1 48 GPIO_ACTIVE_LOW>;
cd-debounce-delay-ms = <100>;
ti,fails-without-test-cd;

With this, you will actually have runtime PM working properly for SD
card while booting off some other interface (e.g. nvme or others) and
card detect will work since GPIO based wake sequence will still be
valid.
