Hello Everyone, This small series adds the initial support (currently just a UART) for TI's AM62L SoC family. The AM62L is a lite, low power and performance optimized family of application processors that are built for Linux application development. AM62L is well suited for a wide range of general-purpose applications with scalable ARM Cortex-A53 core performance and embedded features such as: Multimedia DSI/DPI support, integrated ADC on chip, advanced lower power management modes, and extensive security options for IP protection with the built-in security features. Additionally, the AM62Lx devices includes an extensive set of peripherals that make it a well-suited for a broad range of industrial applications while offering intelligent features and optimized power architecture as well. In addition, the extensive set of peripherals included in AM62Lx enables system-level connectivity, such as: USB, MMC/SD, OSPI, CAN-FD and an ADC. AM62L is a general purpose processor, however some of the applications well suited for it include: Human Machine Interfaces (HMI), Medical patient monitoring , Building automation, Smart secure gateways, Smart Thermostats, EV charging stations, Smart Metering, Solar energy and more. Some highlights of AM62L SoC are: - Single to Dual 64-bit Arm® Cortex®-A53 microprocessor subsystem up to 1.25GHz Integrated Giga-bit Ethernet switch supporting up to a total of two external - 16-bit DDR Subsystem that supports LPDDR4, DDR4 memory types. - Display support: 1x display support over MIPI DSI (4 lanes DPHY) or DPI (24-bit RGB LVCMOS) - Multiple low power modes support, ex: Deep sleep and Standby - Support for secure boot, Trusted Execution Environment (TEE) & Cryptographic Acceleration For more information check out our Technical Reference Manual (TRM) which is located here: https://www.ti.com/lit/pdf/sprujb4 Happy Hacking ~Bryan Changes in v1: - switched to non-direct links so TRM updates are automatic - fixed indentation issues with a few nodes - separated bindings into a different patch - removed current-speed property from main_uart0{} - removed empty reserved-memory{} node - removed serial2 from aliases{} node - corrected the main_uart0{} pinmux - Link: https://lore.kernel.org/all/20241117-am62lx-v1-0-4e71e42d781d@xxxxxx/ Signed-off-by: Bryan Brattlof <bb@xxxxxx> --- Bryan Brattlof (1): dt-bindings: arm: ti: Add binding for AM62L SoCs Vignesh Raghavendra (2): arm64: dts: ti: k3-am62l: add initial infrastructure arm64: dts: ti: k3-am62l: add initial reference board file Documentation/devicetree/bindings/arm/ti/k3.yaml | 6 ++ arch/arm64/boot/dts/ti/Makefile | 3 + arch/arm64/boot/dts/ti/k3-am62l-main.dtsi | 52 ++++++++++++++ arch/arm64/boot/dts/ti/k3-am62l-wakeup.dtsi | 33 +++++++++ arch/arm64/boot/dts/ti/k3-am62l.dtsi | 89 ++++++++++++++++++++++++ arch/arm64/boot/dts/ti/k3-am62l3-evm.dts | 43 ++++++++++++ arch/arm64/boot/dts/ti/k3-am62l3.dtsi | 67 ++++++++++++++++++ arch/arm64/boot/dts/ti/k3-pinctrl.h | 2 + 8 files changed, 295 insertions(+) --- base-commit: 6b51892b31fe83fe7cc8cf69e4bf7721cf08951b change-id: 20241220-am62lx-ca9498efd87e Best regards, -- Bryan Brattlof <bb@xxxxxx>
