Subject[PATCH] arm64: dts: Add support for NXP's LX2160A SoC
Date
The QorIQ LX2160A processor is built in the 16FFC process on
the Layerscape architecture combining sixteen ARM A72 processor
cores with advanced, high-performance datapath acceleration and
network, peripheral interfaces required for networking, wireless
infrastructure, storage, and general-purpose embedded applications.

Features summary:
- Sixteen 32-bit / 64-bit ARM v8 A72 CPUs
- Cache Coherent Interconnect Fabric (CCN508 aka “Eliot”)
- Two 64-bit 3.2GT/s DDR4 SDRAM memory controllers with ECC.
- Data path acceleration architecture (DPAA2)
- 24 Serdes lanes at up to 25 GHz
- Ethernet interfaces
Single WRIOP tile supporting 130Gbps using 18 MACs
Support for 10G-SXGMII (aka USXGMII).
Support for SGMII (and 1000Base-KX)
Support for XFI (and 10GBase-KR)
Support for CAUI4 (100G); CAUI2 (50G) and 25G-AUI(25G).
Support for XLAUI4 (and 40GBase-KR4) for 40G.
Support for two RGMII parallel interfaces.
Energy efficient Ethernet support (802.3az)
IEEE 1588 support.
- High-speed peripheral interfaces
Two PCIe Gen 4.0 8-lane controllers supporting SR-IOV,
Four PCIe Gen 4.0 4-lane controllers.
Four serial ATA (SATA 3.0) controllers.
Two USB 3.0 controllers with integrated PHY
Two Enhanced secure digital host controllers
Two Controller Area Network (CAN) modules
Flexible Serial peripheral interface (FlexSPI) controller.
Three Serial peripheral interface (SPI) controllers.
Nine I2C Controllers.
Four UARTs supporting two 4-pin UART ports or four 2-pin UART ports.
General Purpose IO (GPIO)
- Support for hardware virtualization and partitioning (ARM MMU-500)
- Support for GIC (ARM GIC-500)
- QorIQ platform Trust Architecture 3.0
- One Secure WatchDog timer and one Non-Secure Watchdog timer.
- ARM Generic Timer
- Two Flextimers
- Debug supporting run control, data acquisition, high-speed trace,
performance/event monitoring
- Thermal Monitor Unit (TMU) with +/- 2C accuracy
- Support for Voltage ID (VID) for yield improvement
