Subject: [PATCH 0/2] arm64: dts: ti: introduce basic support for the AM62L

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
