Add basic support for phyCORE-AM64x SoM & phyBOARD-Electra-AM642 CB. The phyCORE-AM64x [1] is a SoM (System on Module) featuring TI's AM64x SoC. It can be used in combination with different carrier boards. This module can come with different sizes and models for DDR, eMMC, SPI NOR Flash and various SoCs from the AM64x family. A development Kit, called phyBOARD-Electra [2] is used as a carrier board reference design around the AM64x SoM. Supported features: * Debug UART * Heartbeat LED * GPIO buttons & LEDs * SPI NOR flash * eMMC * CAN * Ethernet * Micro SD card * I2C EEPROM * I2C RTC * I2C LED Dimmer * USB For more details, see: [1] Product page SoM: https://www.phytec.com/product/phycore-am64x [2] Product page CB: https://www.phytec.com/product/phyboard-am64x Signed-off-by: Wadim Egorov <w.egorov@phytec.de> --- v4: - Do not override led pinmux in carrier board dts file, extend it - Do not mark tscadc0 and mcu_gpio0 nodes as reserved - Drop note about SPI TPM chip support from commit message v3: - Fix regulator name s/vcc-5v0-som/regulator-vcc-5v0-som - Drop nodes currently without YAML schemes and cause dtbs_check errors: - pmic@61 / ti,lp8733 - rtc@52 / trickle-resistor-ohms - leds@62 / nxp,pca9533 - main_spi0 + tpm@1 / infineon,slb9670 v2: - Update commit message - Add links to product pages for SoM & CB - Drop "fixed" from regulator node names - Use generic node names for pmic, tpm, leds & keys - Update compatible of som.dtsi - Remove not needed node labels for pmic, tpm - Remove not needed R5 core mailbox & reserved memory definitions This is use case specific and should not be defined in the som.dtsi - Provide aliases for used devices by SoM & CB - Fixed led definition: Provide proper default-trigger, function & color - Renamed rtc label to i2c_som_rtc --- arch/arm64/boot/dts/ti/Makefile | 1 + .../boot/dts/ti/k3-am64-phycore-som.dtsi | 231 +++++++++++++++ .../dts/ti/k3-am642-phyboard-electra-rdk.dts | 277 ++++++++++++++++++ 3 files changed, 509 insertions(+) create mode 100644 arch/arm64/boot/dts/ti/k3-am64-phycore-som.dtsi create mode 100644 arch/arm64/boot/dts/ti/k3-am642-phyboard-electra-rdk.dts
