[PATCH 2/3] arm64: dts: ti: Add Support for AM642 SoC
Dave Gerlach

Wed Nov 25 00:20:03 EST 2020
The AM642 SoC belongs to the K3 Multicore SoC architecture platform,
providing advanced system integration to enable applications such as
Motor Drives, PLC, Remote IO and IoT Gateways.
Some highlights of this SoC are:
* Dual Cortex-A53s in a single cluster, two clusters of dual Cortex-R5F
MCUs, and a single Cortex-M4F.
* Two Gigabit Industrial Communication Subsystems (ICSSG).
* Integrated Ethernet switch supporting up to a total of two external
ports.
* PCIe-GEN2x1L, USB3/USB2, 2xCAN-FD, eMMC and SD, UFS, OSPI memory
controller, QSPI, I2C, eCAP/eQEP, ePWM, ADC, among other
peripherals.
* Centralized System Controller for Security, Power, and Resource
Management (DMSC).
See AM64X Technical Reference Manual (SPRUIM2, Nov 2020)
for further details: https://www.ti.com/lit/pdf/spruim2
Introduce basic support for the AM642 SoC to enable minimal
ramdisk boot. Introduce a limited set of MAIN domain periperhals
under cbass_main and a placeholder cbass_mcu node for future MCU
domain usage.
