ath12k: recommended regulatory country source for embedded AP products?

Hello,

I'm integrationg the=C2=A0Silex SX-PCEBE module (Qualcomm WCN7850, ath12k) =
on the
ARM-based Toradex Aquila SoM family, using a recent mainline kernel (7.2-rc=
).

Hardware/firmware: wcn7850 hw2.0 (PCI),
WLAN.HMT.1.1.c7-00108-QCAHMTSWPL_V1.0_V2.0_SILICONZ_UPSTREAM-3
(fw_version 0x1103006c).

I'm trying to understand the intended way to set the regulatory country for
ath12k on embedded products where the country is configured by the integrat=
or of
our SoM or at deployment time by the end user.

My current understanding is that ath12k registers the wiphy as self-managed=
, but
userspace regulatory hints, e.g. "iw reg", are ignored in ath12k_reg_notifi=
er()
unless CONFIG_ATH_REG_DYNAMIC_USER_REG_HINTS=3Dy, which in turn depends on
CONFIG_CFG80211_CERTIFICATION_ONUS.

The SMBIOS coounty-code path, looks intended for fixed regional SKUs, Howev=
er,
it is not available on our ARM platform.

So, I have 2 related questions:

1 - Is the expected ath12k model for this type of product to enable=20
ATH_REG_DYNAMIC_USER_REG_HINTS and use userspace regulatory hints before
starting hostapd, with the regulatory responsibility on the product/integra=
tor?


Or is there another mechanism you would recomment for this use case?

2 - Since ath12k is a self-managed regulatory device and the firmware owns =
and
enforces the regulatory database, is the CFG80211_CERTIFICATION_ONUS gate
intended to apply to this case as well?

In other words, should a userspace-selected country for a self-managed ath1=
2k
device be treated the same as dynamic user regulatory hints for non-self-ma=
naged
devices, or is this dependency inherited from the common ath regulatory mod=
el?

Without a country, the ath12k falls back to world "00", where 5 GHz AP oper=
ation
is blocked by NO_IR.

Thanks,
