6248b20e32 arm64: dts: ti: k3-am64: 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).

8d5bfa637f arm64: dts: ti: k3-am64: Add phase tags marking
bootph-all as phase tag was added to dt-schema
(dtschema/schemas/bootph.yaml) to describe various node usage during
boot phases with DT.

On TI K3 AM642 SoC, only esm nodes are exclusively used by R5
bootloader, rest of the dts nodes with bootph-* are used by later boot
stages also.

Add bootph-all for all other nodes that are used in the bootloader on
K3 AM642 SoC, and bootph-pre-ram is not needed specifically for any
other node in kernel dts.

bb3d657872 arm64: dts: ti: k3-am642-sk|evm: Drop bootargs, add aliases
Drop bootargs and add aliases based on base pinout of SK as per [1] and
evm per [2].

Indices chosen attempt to maintain some level of consistency with
existing aliases.

While at this, drop a extra EoL. While this patch could be split, it
seems trivial to add additional cleanup steps.

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.

de60edf1be arm64: dts: ti: k3-am64: 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.

2aeb0696b8 arm64: dts: ti: k3-am64: Add ESM0 to device memory map
AM64x SoCs have two ESM modules, with one in MAIN voltage domain and the
other in MCU voltage domain. The error output from Main ESM module can
be routed to the MCU ESM module. The error output of MCU ESM can be
configured to reset the device. The MCU ESM configuration address space
is already opened and this patch opens the MAIN ESM configuration
address space.

For ESM details please refer technical reference manual at

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.

3753b12877 arm64: dts: ti: k3-am64-main: Add CPSW DT node
Add CPSW3g DT node with two external ports, MDIO and CPTS support. For
CPSW3g DMA channels the ASEL is set to 15 (AM642x per DMA channel coherency
feature), so that CPSW DMA channel participates in Coherency and thus avoid
need to cache maintenance for SKBs. This improves bidirectional TCP
performance by up to 100Mbps (on 1G link).

8abae9389b arm64: dts: ti: Add support for AM642 SoC
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 ramdisk or MMC
boot. Introduce the sdhci, i2c, spi, and uart MAIN domain periperhals
under cbass_main and the i2c, spi, and uart MCU domain periperhals
under cbass_mcu.
