89359 Linux: regdb vs. CLM

[StLe_4369261]

Hi

Normally, in Linux systems, country specific frequency-band and power settings are defined and handled via regdb.
The 89359 brakepad driver uses a CLM blob to define band and power settings.
How is the relation of CLM to regdb in this driver? Are regdb values used by the driver or can the settings only be done via CLM blob?

Kind regards

Stefan

The wireless-regdb would provide the kernel with the regulatory database but it has several disadvantages. For eg; every update to the db.txt file that you would be using to update the regulatory specifications, you would have to recompile the kernel. When using bcmdhd or brcmfmac driver , the regdb values are ignored and only CLM blob values are considered by utilities like iw, wpa_supplicant etc.

Was you kernel built with the following flag CONFIG_CFG80211_INTERNAL_REGDB.

Thx for clarification.
Yes, we are building with CONFIG_CFG80211_INTERNAL_REGDB=y
