5579986638 arm64: dts: ti: k3-am65: Include entire FSS region in ranges
Add FSS regions at 0x50000000, 0x400000000, and 0x600000000. Although
not used currently by the Linux FSS driver, these regions belong to
the FSS and should be included in the ranges mapping.

While here, a couple of these numbers had missing zeros which was
hidden by odd alignments, fix both these issues.

2822c791af arm64: dts: ti: k3-am65: Add MIT license along with GPL-2.0
Modify license to include dual licensing as GPL-2.0-only OR MIT
license for SoC and TI evm device tree files. This allows for Linux
kernel device tree to be used in other Operating System ecosystems
such as Zephyr or FreeBSD.

While at this, update the GPL-2.0 to be GPL-2.0-only to be in sync
with latest SPDX conventions (GPL-2.0 is deprecated).

While at this, update the TI copyright year to sync with current year
to indicate license change (and add it at least for one file which was
missing TI copyright).

ffc449e016 arm64: dts: ti: k3-am65: Drop aliases
iot boards have always defined their own aliases and with the base-board
defining it's own aliases, there are no pending boards depending on
common aliases defined in SoC level.

aliases are meant to be defined appropriately based on the exposed
interfaces at a board level, drop the aliases defined at SoC level.

fe49f2d776 arm64: dts: ti: Use local header for pinctrl register values
The DTS uses hardware register values directly in pin controller pin
configuration and not an abstraction of any form.

These definitions were previously put in the bindings header to avoid
code duplication and to provide some context meaning (name), but they
do not fit the purpose of bindings.

Store the constants in a header next to DTS and use them instead of
bindings.

8cae268b70 arm64: dts: ti: k3-am65: Fix gic-v3 compatible regs
Though GIC ARE option is disabled for no GIC-v2 compatibility,
Cortex-A53 is free to implement the CPU interface as long as it
communicates with the GIC using the stream protocol. This requires
that the SoC integration mark out the PERIPHBASE[1] as reserved area
within the SoC. See longer discussion in [2] for further information.

Update the GIC register map to indicate offsets from PERIPHBASE based
on [3]. Without doing this, systems like kvm will not function with
gic-v2 emulation.

f54e1a97c8 arm64: dts: ti: ti-k3*: Introduce aliases for mmc nodes
Since probe order of mmc can vary depending on device tree dependencies,
Lets try and introduce a consistent definition of what mmc0, 1 are
across platforms.

NOTE: Certain platforms may choose to have overrides due to various
legacy reasons, we permit that in the board specific alias definition.

Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:

3bc1572068 arm64: dts: ti: k3-am65: Change #address-cells and #size-cells of interconnect to 2
AM65 has two PCIe controllers and each PCIe controller has '2' address
spaces one within the 4GB address space of the SoC and the other above
the 4GB address space of the SoC (cbass_main) in addition to the
register space. The size of the address space above the 4GB SoC address
space is 4GB. These address ranges will be used by CPU/DMA to access
the PCIe address space. In order to represent the address space above
the 4GB SoC address space and to represent the size of this address
space as 4GB, change address-cells and size-cells of interconnect to 2.

Since OSPI has similar need in MCU Domain Memory Map, change
address-cells and size-cells of cbass_mcu interconnect also to 2.

ea47eed33a arm64: dts: ti: Add Support for AM654 SoC
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.
