[PATCH v4 0/3] arm64: dts: ti: introduce basic support for the AM62L

[Bryan Brattlof]

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@xxxxxx/

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@xxxxxx

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@xxxxxx
