Is Wi-Fi Wake On Wireless supported on the Sona TI351?

Answer

Wake On Wireless is supported on the Sona TI351 Wi-Fi interface, however it requires that Out Of Band (GPIO) IRQ is used via the SDIO_WAKE#/HOST_IRQ_WL signal. Note that when using the M.2 1216 module this signal is active high (HOST_IRQ_WL), and when using the M.2 2230 module this signal is inverted on the carrier board (SDIO_WAKE#) to be active low for compliance with the M.2 specification.
