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

Happy Hacking

Changes from 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/ (local)

Changes from 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 (local)

Changes from 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 (local)

Changes from v4:
- corrected copyright date
- used the ranges property for the fss{} node
- converted control MMR's space into a syscon{} node
- Link to v4: https://lore.kernel.org/r/20250407-am62lx-v4-0-ce97749b9eae@ti.com (local)

Changes from v5:
- added new compatible for the am62l pinmux driver
- increased thermal trip point to 125C
- reduced size of &conf its correct size of 0x380000
- replaced dss with display: s/dss@/display@/
- expanded chipid to include the JTAG_USER_ID information
- removed nodes requiring parent clocks until sorted in firmware
- expanded &wkup_conf length to properly contain the &usb_phy_ctrl
- moved back to &wkup_conf as a simple bus and grouped both 
  &usb*_phy_ctrl into one syscon node rather than individual nodes
- Link to v5: https://lore.kernel.org/r/20250507-am62lx-v5-0-4b57ea878e62@ti.com (local)

Changes from v6:
- moved thermal-zones{} into the k3-am62l3-evm.dts to allow other boards 
  to select whichever thermal nodes trip points they wish.
- removed dss{} for now until binding doc is updated.
