Suspend or Runtime suspend?

The it is the runtime suspend routine for omap_hsmmc.c

	mmc1_pins: pinmux_mmc1_pins {
		pinctrl-single,pins = <
			0x0fc 0x38	/* MMC0_DAT0 */
			0x0f8 0x38	/* MMC0_DAT1 */
			0x0f4 0x38	/* MMC0_DAT2 */
			0x0f0 0x38	/* MMC0_DAT3 */
			0x100 0x38	/* MMC0_CLK */
			0x104 0x38	/* MMC0_CMD */
			0x88  0x07	/* GPMC_CSN3 -> GPIO2_0 */
		>;
	};

	mmc1_sleep_pins: pinmux_mmc1_sleep_pins {
		pinctrl-single,pins = <
			0x0fc 0x3f	/* MMC0_DAT0 */
			0x0f8 0x3f	/* MMC0_DAT1 */
			0x0f4 0x3f	/* MMC0_DAT2 */
			0x0f0 0x3f	/* MMC0_DAT3 */
			0x100 0x3f	/* MMC0_CLK */
			0x104 0x3f	/* MMC0_CMD */
			0x88  0x17	/* GPMC_CSN3 -> GPIO2_0 PULL UP */
		>;
	};

	mmc1_cirq_pin: pinmux_cirq_pin {
		pinctrl-single,pins = <
			0x0f8 0x3f	/* MMC0_DAT1 as GPIO2_28 */
		>;
	};

	wlan0_pwrseq: pwrseq {
		compatible = "mmc-pwrseq-simple";
		reset-gpios = <&gpio2 0 GPIO_ACTIVE_LOW>;
		clocks = <&clk_32768_ck>;
		clock-names = "ext_clock";
	};

&mmc1 {
	status = "okay";
	pinctrl-names = "default", "idle", "sleep";
	pinctrl-0 = <&mmc1_pins>;
	pinctrl-1 = <&mmc1_cirq_pin>;
	pinctrl-2 = <&mmc1_sleep_pins>;
	interrupts-extended = <&intc 64 &gpio2 28 0>;

^^ you can define IRQ type here

 &gpio2 28 IRQ_TYPE_LEVEL_LOW

	ti,non-removable;
	bus-width = <4>;
	vmmc-supply = <&ldo2_reg>;
	vmmc_aux-supply = <&vmmc>;
	keep-power-in-suspend;
	enable-sdio-wakeup;
	mmc-pwrseq = <&wlan0_pwrseq>;
};





Is there any other suggestion for mwifiex that I should try out? Or
is there any way in omap_hsmmc to specify the wakeup interrupt
type (IRQF_TRIGGER_LOW) while using generic wakeup IRQ
mechanism. I could not find it, but I may be missing something.

How your irqs defined in DT? Could you provide mmc+wifi nodes?
