From 1a7d97c2d3868c7c7b74b26d4af210e22666171b Mon Sep 17 00:00:00 2001 From: Francesco Valla Date: Thu, 15 Jan 2026 18:11:34 +0100 Subject: [PATCH] arm64: dts: imx93-11x11-frdm: enable additional devices Enable additional devices on the i.MX93 FRDM board: - CAN port and associated transceiver - Bluetooth portion of the IW612 chipset - WiFi SDIO port - user buttons The WiFi portion of the on-board IW612 chipset is still not supported upstream, but since SDIO is a discoverable bus it will be probed once it is.
