[PATCH do not merge 0/4] wifi: mwifiex: add iw61x support

[Sascha Hauer]

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.

[PATCH do not merge 1/4] wifi: mwifiex: release firmware at remove time

[Sascha Hauer]

With VDLL support the device will request parts of the firmware during
runtime, so instead of releasing the firmware immediately after initial
firmware upload, release it during device deregistration.

FIXME: I am not sure if we run into trouble with the firmware framework
when we don't release the firmware. We might have to copy it over to
some private buffer instead of just keeping it around.

FIXME: we might want to limit the release firmware at remove time to the
devices that actually need it.

[PATCH do not merge 2/4] wifi: mwifiex: handle VDLL

[Sascha Hauer]

Some adapters send events to the Kernel requesting VDLL images. When we
receive such an event we have to upload parts of the firmware image to
the device.

When the firmware requests a VDLL image then we have to bypass the
pending command queue and have to send it immediately. Failing to do
so will cause every other command sent from the queue to timeout.

There is this check currently in mwifiex_download_vdll_block():

	if (adapter->cmd_sent) {
		mwifiex_dbg(adapter, MSG, "%s: adapter is busy\n", __func__);
		return -EBUSY;
	}

The downstream driver has this check as well. However, the downstream
driver tries to defer sending the VDLL command when this happens. It
sets a variable in the private driver struct where the main process
picks it up later.  I am not sure if this can work, because when
adapter->cmd_sent is true then it's already too late, we already missed
to send the VDLL image before the next command. In my tests I never saw
the above trigger, but this surely a place to have a closer look at.

Shared the handling of VDLL events in the nxpwifi driver:  
- When “cmd_sent” is true: The VDLL block download is deferred, with its offset and length stored for later processing.
- When no command is active (“cmd_sent” is false): The VDLL block is downloaded immediately in the nxpwifi_main_process.

[PATCH do not merge 3/4] wifi: mwifiex: wait longer for SDIO card status

[Sascha Hauer]

The IW61x needs longer than the currently used MAX_POLL_TRIES for some
operations. Increase the value to 10000 * 10us = 100000us as done in the
downstream driver as well.

[PATCH do not merge 4/4] wifi: mwifiex: add iw61x support

[Sascha Hauer]

This adds iw61x aka SD9177 support to the mwifiex driver. It is named
SD9177 in the downstream driver, I deliberately chose the NXP name in
the driver.

Is there a way to have BT over SDIO with iw61x? I was sure only sd-uart was
possible.

The communication to the Bluetooth module indeed is UART only.

I think nxp/sdsd_nw61x.bin contains firmwares for both the WiFi and
Bluetooth chip. When using this you can use the Bluetooth UART directly
without uploading a separate Bluetooth firmware.

nxp/sd_w61x.bin only contains the WiFi firmware, so you have to
upload a separate Bluetooth firmware over the UART interface.

If that the case what you did here is not correct.

The 2 firmware files here are used file depending on the BT host interface used
on the Wi-Fi/BT chip, and this is read from some strapping register. See commit
255ca28a659d ("mwifiex: Select firmware based on strapping").

BTW, this name sdsd_nw61x.bin is confusing, I would have expected this to be
something like sduart_nw61x.bin.

You are right, there seem to be some things mixed up. I'll have a look
into it for the next round.

Looking at downstream driver looks like based on chip revision firmware
files will be different. My best finding on the firmware files naming about
this chip was this thread [1] on the NXP forums.

Hi Sascha,

Thanks for sharing these patches. To test, I applied them to our
downstream branch based on the NXP BSP 6.6.52-2.2.0 and can confirm that
the driver works well on our iMX95-based board which uses a ublox
MAYA-W260 (IW611) for WiFi (SDIO) and BT (UART). Both STA and AP mode
looked good to me.

Kind regards,
Ernest

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.

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.
