Subject: [RFC PATCH 0/2] ath10k USB support (QCA9377)
Hello everyone,
apparently there have been several tries for adding ath10k USB support, see
[1] & [2]. There are probably even more.
This series is a first step for supporting my actual device,
a Silex SX-USBAC. This is a Bluetooth & WiFi combo device.
I picked commit 131da4f5a5b9 ("HACK: ath10k: add start_once support") from
[2] and extracted the ath10k_hw_params_list entry from [3].
Since v5.9, the base of [3], other required changes have already been
integrated.
For now I tested a very simple STA mode usage profile, using
wpa_supplicant on a WPA interface. AP is untested, module unloading not
supported, probably affected by the firmware start/stop patch 1 adds a
workaround.
Reading the other, older series, apparently a lot has been merged already,
but I do not know what is still missing fpr proper USB support.
I would like to have a discussion for how to add support so the device is
at least probing and can be used rudimentary.
Best regards,
Alexander
