Subject: [PATCH v3 0/3] Add support for AM62D2 SoC and EVM

This patch series adds support for the AM62D SoC and its evaluation
module (EVM) board. The AM62D SoC is a high-performance Digital
Signal Processing (DSP) device with a quad-core Cortex-A53 cluster,
dual Cortex-R5F cores, and a Cx7 DSP core with Matrix Multiplication
Accelerator (MMA). It features a range of peripherals, including
multichannel audio serial ports, Ethernet, UARTs, SPI, I2C, USB, and
more.

The EVM board is a low-cost, expandable platform designed for the AM62D2
SoC, having 4GB LPDDR4 RAM, Gigabit Ethernet expansion connectors, audio
jacks, USB ports, and more.

This SoC is part K3 AM62x family, which includes the AM62A and AM62P
variants. While the AM62A and AM62D are largely similar, the AM62D is
specifically targeted for general-purpose DSP applications, whereas the
AM62A focuses on edge AI workloads. A key distinction 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, which impacts embedded
software development.

This patch series includes updates to the dts and dtsi files, device tree
bindings, and pin control header files to support the AM62D SoC and EVM
board.

Change Log:
V2 -> V3:
	-Added bootph-all property to essential device nodes.
	-Updated reserved memory for ATF.
	-Introduce common dtsi files for AM62A and AM62D.

V1 -> V2: Fixed indentation and build errors.
