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 Signed-off-by: Nishanth Menon --- Changes since RFC: * Dropped the generic terminology for compatibles previous RFC: https://patchwork.kernel.org/patch/10447643/ Documentation/devicetree/bindings/arm/ti/k3.txt | 23 +++++++++++++++++++++++ MAINTAINERS | 7 +++++++ 2 files changed, 30 insertions(+) create mode 100644 Documentation/devicetree/bindings/arm/ti/k3.txt diff --git a/Documentation/devicetree/bindings/arm/ti/k3.txt b/Documentation/devicetree/bindings/arm/ti/k3.txt new file mode 100644 index 000000000000..6a059cabb2da --- /dev/null +++ b/Documentation/devicetree/bindings/arm/ti/k3.txt @@ -0,0 +1,23 @@ +Texas Instruments K3 Multicore SoC architecture device tree bindings +-------------------------------------------------------------------- + +Platforms based on Texas Instruments K3 Multicore SoC architecture +shall follow the following scheme: + +SoCs +---- + +Each device tree root node must specify which exact SoC in K3 Multicore SoC +architecture it uses, using one of the following compatible values: + +- AM654 + compatible = "ti,am654"; + +Boards +------ + +In addition, each device tree root node must specify which one or more +of the following board-specific compatible values: + +- AM654 EVM + compatible = "ti,am654-evm", "ti,am654"; diff --git a/MAINTAINERS b/MAINTAINERS index 9d5eeff51b5f..fbd93eee41ae 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -2087,6 +2087,13 @@ L: linux-kernel@vger.kernel.org S: Maintained F: drivers/memory/*emif* +ARM/TEXAS INSTRUMENTS K3 ARCHITECTURE +M: Tero Kristo +M: Nishanth Menon +L: linux-arm-kernel@lists.infradead.org (moderated for non-subscribers) +S: Supported +F: Documentation/devicetree/bindings/arm/ti/k3.txt + ARM/TEXAS INSTRUMENT KEYSTONE ARCHITECTURE M: Santosh Shilimkar L: linux-arm-kernel@lists.infradead.org (moderated for non-subscribers)
