Subject: [PATCH v4 2/2] arm64: dts: ti: Add k3-am67a-beagley-ai
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 v3:
- removed extra blank lines
- Krzysztof/Nishanth: switch to consistent regulator-x syntax along with dropping uppercase
- Roger: removed un-used internal network clock: OBSCLK
- Nishanth: fixed order of bootph-all before vendor prefixes
- Nishanth: removed unused default-trigger with led-0 (dtbs_check failure)
Changes since v2:
- added led indictors
- sdhci1 use MMC1_SDCD.GPIO1_48 for card detect
- cleaned up order of status = "okay"
- wkup_i2c0 moved to 100000
- eeprom added atmel,24c32
- rtc added dallas,ds1340
- sdhci1 use ti,fails-without-test-cd
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
