This series adds iw61x support to the mwifiex driver. It works for me,
but is not yet ready to be merged. Some people showed interest in it, so
I am sending it here.

All testing and review feedback appreciated.

During startup I get these messages:

[   12.078010] mwifiex_sdio mmc1:0001:1: Unknown GET_HW_SPEC TLV type: 0xff
[   12.078018] mwifiex_sdio mmc1:0001:1: Unknown GET_HW_SPEC TLV type: 0xff
[   12.078024] mwifiex_sdio mmc1:0001:1: Unknown GET_HW_SPEC TLV type: 0x23e
[   12.078029] mwifiex_sdio mmc1:0001:1: Unknown GET_HW_SPEC TLV type: 0x25c

Not sure what these are about, I can't see these handled in the
downstream mwifiex driver as well. Could also be there is some parsing
error. Nevertheless the driver seems to work.

The series applies to v6.14, but should apply to my mwifiex cleanup
series as well.

Sharing this, so maybe you can help on having a way forward for iw61x
chip supported with mainline Linux.

In the downstream driver, branch lf-6.12.3_1.0.0, t his seems to be
MrvlIEtypes_fw_cap_info_t for things like:

FW_CAPINFO_EXT_802_11AX, FW_CAPINFO_EXT_6G ....

This looks like MrvlIEtypes_Secure_Boot_Uuid_t. Doesn't seems too
important.

Yep, it is working. Thank you! I am testing this on FRDM-iMX93, which has
IW612 revision 1.0.

I have to use nxp/sd_w61x_v1.bin.se on this board and NULL firmware_sdiouart
because it seems that firmware return 1 as "strap" value, even if WiFi
is definitely connected over SDIO.

Regards,
Ivan

Wi-Fi is always connected over SDIO (for IW61x), the strapping is
related to the interface used for BT. In the past it was common to have
options for having BT over SDIO or UART or USB, but for IW61x it seems
that UART is the only available option.
