Hello Everyone,

This small series adds the initial support (currently just a UART) for
TI's AM62L SoC family.

The AM62L is a lite, low power and performance optimized family of
application processors that are built for Linux application development.
AM62L is well suited for a wide range of general-purpose applications
with scalable ARM Cortex-A53 core performance and embedded features such
as: Multimedia DSI/DPI support, integrated ADC on chip, advanced lower
power management modes, and extensive security options for IP protection
with the built-in security features.

Additionally, the AM62Lx devices includes an extensive set of
peripherals that make it a well-suited for a broad range of industrial
applications while offering intelligent features and optimized power
architecture as well. In addition, the extensive set of peripherals
included in AM62Lx enables system-level connectivity, such as: USB,
MMC/SD, OSPI, CAN-FD and an ADC.

AM62L is a general purpose processor, however some of the applications
well suited for it include: Human Machine Interfaces (HMI), Medical
patient monitoring , Building automation, Smart secure gateways, Smart
Thermostats, EV charging stations, Smart Metering, Solar energy and
more.

Some highlights of AM62L SoC are:
- Single to Dual 64-bit Arm® Cortex®-A53 microprocessor subsystem up to
1.25GHz Integrated Giga-bit Ethernet switch supporting up to a total
of two external
- 16-bit DDR Subsystem that supports LPDDR4, DDR4 memory types.
- Display support: 1x display support over MIPI DSI (4 lanes DPHY) or
DPI (24-bit RGB LVCMOS)
- Multiple low power modes support, ex: Deep sleep and Standby
- Support for secure boot, Trusted Execution Environment (TEE) &
Cryptographic Acceleration

Changes in v1:
- switched to non-direct links so TRM updates are automatic
- fixed indentation issues with a few nodes
- separated bindings into a different patch
- removed current-speed property from main_uart0{}
- removed empty reserved-memory{} node
- removed serial2 from aliases{} node
- corrected the main_uart0{} pinmux
- Link: https://lore.kernel.org/all/20241117-am62lx-v1-0-4e71e42d781d@ti.com/

Changes in v2:
- alphabetized phandles
- corrected macro and node names for main_uart0 pinmux
- Link to v2: https://lore.kernel.org/r/20250108-am62lx-v2-0-581285a37d8f@ti.com

Changes in v3:
- added more nodes which have been validated
- added link to data sheet which is now public
- Link to v3: https://lore.kernel.org/r/20250109-am62lx-v3-0-ef171e789527@ti.com

Changes in v4:
