From ad527a91cb1d1a43734f51acd49e5a1f8ec67682 Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Tue, 26 Jun 2018 11:26:11 -0500 Subject: [PATCH 1/5] dt-bindings: arm: ti: Add bindings 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 Reviewed-by: Tony Lindgren Signed-off-by: Nishanth Menon Reviewed-by: Rob Herring Signed-off-by: Tony Lindgren --- .../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) From c77245722fb47e45db22f053d449c030d3038dde Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Tue, 26 Jun 2018 11:26:12 -0500 Subject: [PATCH 2/5] arm64: Add support for TI's K3 Multicore SoC architecture Add support for Texas Instrument's K3 Multicore SoC architecture processors.

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.

There are two basic configurations defined which include an "EVM" configuration and "IDK" (Industrial development kit) which differ in the specific combination of daughter cards that are used. To simplify support, we choose to support just the base board as the core device tree file and all daughter cards would be expected to be device tree overlays.
