QCA9377 ath10k SDIO issues

[Anthony Needles]

Hi all,

I am trying to get the Silex SC-SDCAC Wi-Fi SD card, which has a
QCA9377-3, working on my system. This is on an i.MX 8ULP dev board,
which exposes SDIO/MMC connections over an M.2 connector. Between the
Wi-Fi module and the dev board is an M.2 to SDIO adaptor, which just
passes through the SDIO CLK/CMD/DATA pins, GND, and VCC. My Linux
kernel version is 5.15.53. I am using the ath10k driver as it should
support driving the QCA9377 over SDIO. The Linux development is being
done with Yocto.

The MMC bus can detect the QCA9377 and the ath10k starts
initialization. However, there seems to be an issue with the firmware
and/or board files. I am using linux-firmware 20220509 from
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git.
Specifically, I am installing board.bin, board-2.bin,
firmware-sdio-5.bin, and notice_ath10k_firmware-sdio-5.txt from
ath10k/QCA9377/hw1.0 to /lib/firmware/ath10k/QCA9377/hw1.0/ on my
target rootfs.

As seen at the bottom of this post, the MMC bus can find the SDIO card
just fine. I verified that the firmware version is as expected, but
then it fails to fetch the board data from board-2.bin. Is there a
lack of this board in the upstream for this board file? There then
seems to be a bunch of timeout/busy errors when attempting to drive
the QCA9377. I think this could be a card firmware issue but may not
be.

Please let me know if you need any more info from me.
