/*
* NOTE: This DTS file is wrote for plugging in Murata 1MW M.2
* into SD2 slot by using Murata uSD-to-M.2 Adapter.
*
* By default, OOB IRQ is not enabled since i.MX6SX SDB board needs to rework.
* How to enable OOB IRQ ?
* HW rework:
* Install R328 on i.MX6SX SDB board.
* SW change:
* pinctrl_wifi: wifigrp {
* fsl,pins = <
* MX6SX_PAD_ENET1_RX_CLK__GPIO2_IO_4 0x0b001
* >;
* };
* brcmf: bcrmf@1 {

* interrupt-parent = <&gpio2>;
* interrupts = <4 IRQ_TYPE_LEVEL_LOW>;
