[RFC PATCH 0/5] Add initial support for AM62D2-EVM

[Paresh Bhagat]

The AM62D2 SoC, part of the K3 architecture, is built for high-performance
DSP tasks in automotive audio, pro audio, radar, sonar, and medical
imaging. It features up to four Cortex-A53 cores (1.4GHz), two Cortex-R5F
cores, and a C7x DSP with 2 TOPS MMA. Key interfaces include multi-channel
McASP audio, TSN-capable Gigabit Ethernet, and a range of peripherals
(UART, SPI, I2C, CAN, USB, eMMC/SD, OSPI, CSI). It supports LPDDR4/DDR4,
secure boot with hardware security, and low-power modes with
CAN/GPIO/UART wakeup.

AM62D2-EVM evaluation module (EVM) is a low-cost expandable platform
board designed for AM62D2 SoC from TI. It supports the following
interfaces:

* 4 GB LPDDR4 RAM
* x2 Gigabit Ethernet expansion connectors
* x4 3.5mm TRS Audio Jack Line In
* x4 3.5mm TRS Audio Jack Line Out
* x2 Audio expansion connectors
* x1 Type-A USB 2.0, x1 Type-C dual-role device (DRD) USB 2.0
* x1 UHS-1 capable micro SD card slot
* 32 GB eMMC Flash
* 512 Mb OSPI NOR flash
* x4 UARTs via USB 2.0-B
* XDS110 for onboard JTAG debug using USB
* Temperature sensors, user push buttons and LEDs

Also resuse Soc specific files from AM62A. A key distinction from AM62A
is that the AM62D does not include multimedia components such as the
video encoder/decoder, MJPEG encoder, Vision Processing Accelerator
(VPAC) for image signal processing, or the display subsystem.
Additionally, the AM62D has a different pin configuration compared to
the AM62A.
