From: Michael Walle Date: Fri, 17 Oct 2025 13:50:45 +0000 (+0200) Subject: arm64: dts: ti: Add support for Kontron SMARC-sAM67 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1c3c4df06f9dee41bff60b93d9f0e67500f798f7;p=thirdparty%2Fkernel%2Fstable.git arm64: dts: ti: Add support for Kontron SMARC-sAM67 Add device tree support for the Kontron SMARC-sAM67 module, which is based on a TI AM67A SoC. The module features: * Quad-core AM67A94 at 1.4GHz with 8 GiB RAM * 64 GiB eMMC, 4 MiB SPI flash for failsafe booting * Dedicated RTC * Multiple interfaces: 4x UART, 2x USB 2.0/USB 3.2, 2x GBE, QSPI, 7x I2C, * Display support: 2x LVDS, 1x DSI (*), 1x DP (*) * Camera support: 4x CSI (*) * Onboard microcontroller for boot control, failsafe booting and external watchdog (*) not yet supported by the kernel There is a base device tree and overlays which will add optional features. At the moment there is one full featured variant of that board whose device tree is generated during build by merging all the device tree overlays.
