      arm64: dts: ti: Add support for AM654 EVM base board · d0a064be
      Nishanth Menon authored
      The EValuation Module(EVM) platform for AM654 consists of a
      common Base board + one or more of daughter cards, which include:
      a) "Personality Modules", which can be specific to a profile, such as
       ICSSG enabled or Multi-media (including audio).
      b) SERDES modules, which may be 2 lane PCIe or two port PCIe + USB2
      c) Camera daughter card
      d) various display panels
      
      Among other options. There are two basic configurations defined which
      include an "EVM" configuration and "IDK" (Industrial development kit)
      which differ in the specific combination of daughter cards that are
      used.
      
      To simplify support, we choose to support just the base board as the
      core device tree file and all daughter cards would be expected to be
      device tree overlays.

      arm64: dts: ti: Add Support for AM654 SoC · ea47eed3
      Nishanth Menon authored
      The AM654 SoC is a lead device of the K3 Multicore SoC architecture
      platform, targeted for broad market and industrial control with aim to
      meet the complex processing needs of modern embedded products.
      
      Some highlights of this SoC are:
      * Quad ARMv8 A53 cores split over two clusters
      * GICv3 compliant GIC500
      * Configurable L3 Cache and IO-coherent architecture
      * Dual lock-step capable R5F uC for safety-critical applications
      * High data throughput capable distributed DMA architecture under NAVSS
      * Three Gigabit Industrial Communication Subsystems (ICSSG), each with dual
        PRUs and dual RTUs
      * Hardware accelerator block containing AES/DES/SHA/MD5 called SA2UL
      * Centralized System Controller for Security, Power, and Resource
        management.
      * Dual ADCSS, eQEP/eCAP, eHRPWM, dual CAN-FD
      * Flash subsystem with OSPI and Hyperbus interfaces
      * Multimedia capability with CAL, DSS7-UL, SGX544, McASP
      * Peripheral connectivity including USB3, PCIE, MMC/SD, GPMC, I2C, SPI,
        GPIO
      
      See AM65x Technical Reference Manual (SPRUID7, April 2018)
      for further details: http://www.ti.com/lit/pdf/spruid7
      
      NOTE:
      1. AM654 is the first of the device variants, hence we introduce a
         generic am65.dtsi.
      2. We indicate the proper bus topology, the ranges are elaborated in
         each bus segment instead of using the top level ranges to make sure
         that peripherals in each segment use the address space accurately.
      3. Peripherals in each bus segment is maintained in a separate dtsi
         allowing for reuse in different bus segment representation from a
         different core such as R5. This is also the reason for maintaining a
         1-1 address map in the ranges.
      4. Cache descriptions follow the ARM64 standard description.
      
      Further tweaks may be necessary as we introduce more complex devices,
      but can be introduced in context of the device introduction.
