From: Max Krummenacher Date: Tue, 11 Nov 2025 15:16:14 +0000 (+0100) Subject: arm64: dts: freescale: add Toradex SMARC iMX95 X-Git-Tag: v6.19-rc1~100^2~20^2 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=90bbe88e0ea61bf3ab2376b0497bacf42b66e4a9;p=thirdparty%2Fkernel%2Flinux.git arm64: dts: freescale: add Toradex SMARC iMX95 Add DT support for Toradex SMARC iMX95 SoM and Development carrier board. The module consists of an NXP i.MX95 family SoC, up to 16GB of LPDDR5 RAM and up to 128GB of storage, a USB 3.0 Host Hub and 2.0 OTG, two Gigabit Ethernet PHYs, a 10 Gigabit Ethernet interface, an I2C EEPROM and Temperature Sensor, an RX8130 RTC, a Quad/Dual lane CSI interface, and some optional addons: TPM 2.0, DSI, LVDS, DisplayPort (through a DSI-DP bridge), and Wi-Fi/BT module.
