Hi Experts,
I am trying to migrate the WLAN code from the Linux SDK 6 to 7 by updating the DTS file.
I have added the following lines of code into EVMSK DTS file with reference to schematic references.
/* wl12xx/wl18xx card on mmc2 */
mmc2_pins: pinmux_mmc2_pins {
pinctrl-single,pins = <
0x000 0x31 /* gpmc_ad0.mmc1_dat0, INPUT_PULLUP | MODE3 */

0x00C 0x31 /* gpmc_ad3.mmc1_dat3, INPUT_PULLUP | MODE3 */
0x084 0x32 /* gpmc_csn2.mmc1_cmd, INPUT_PULLUP | MODE3 */
0x080 0x32 /* gpmc_csn1.mmc1_clk, INPUT_PULLUP | MODE3 */
>;
};
/* wl12xx/wl18xx card enable/irq GPIOs. */
wlan_pins: pinmux_wlan_pins {
pinctrl-single,pins = <
0x40 0x07 /* gpmc_a0.gpio1_16, OUTPUT | MODE7 */
0x070 0x27 /* mcasp0_ahclkr.gpio3_17, INPUT | MODE7 */
0x07C 0x17 /* mcasp0_ahclkx.gpio3_21, OUTPUT_PULLUP | MODE7 */
>;
};
wlcore {
compatible = "wlcore";
gpio = <113>; /* Bank3, pin17 */
/*
* TODO: use edge irqs for suspend/resume.
* in newer kerenls, we seem to miss interrupts when
* working with edge irqs, so revert back to level irqs.
*/
/* platform-quirks = <1>; */
/* if a 12xx card is there, configure the clock to
WL12XX_REFCLOCK_38_XTAL */
board-ref-clock = <4>;
};

dev_name = "/dev/ttyO1";

};

But it doesn't worked out.
The bootup log captured is here as follows,
