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.

WiFi was tested using the nxpwifi driver proposed in [1].
