commit a81e5442d796ccfa2cc97d205a5477053264d978 upstream.
The TI sci-clk driver can scan the DT for all clocks provided by system
firmware and does this by checking the clocks property of all nodes, so
we must add this to the dwc3 nodes so USB clocks are available.
Without this USB does not work with latest system firmware i.e.
[ 1.714662] clk: couldn't get parent clock 0 for /interconnect@100000/dwc3@4020000

commit 389ce1a7c5279ebfb682fab220b4021b2bd49c8b upstream.
The gic-its node unit-address has an additional zero compared
to the actual reg value. Fix it.

The AM65 SoC has 2MB MSMC RAM. Add this as a mmio-sram
node so drivers can use it via genpool API.
Following areas are marked reserved:
- Lower 128KB for ATF
- 64KB@0xf0000 for SYSFW
- Upper 1MB for cache
The reserved locations are subject to change at runtime by
the bootloader.

Populate power-domain property for UART nodes, this is required for
Linux to enable UART clocks via PM calls. Without this UART instances
not initialized by bootloader (like main_uart1) fails to work in Linux.
Also, drop current-speed property from main_uart1 and main_uart2 nodes
as these UARTs are not initialized before Linux boots up and current
speed is unknown.

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.

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.
