dt-bindings: net: wireless: add flag marvell,invalid-reg-hint-in-rom
WRT3200ACM and WRT32x routers always report a fixed US regulatory domain
from the mwifiex ROM, which conflicts with the platform regulatory
configuration on units sold outside the US market. For example:
- phy0 mwlwifi 5 GHz, hard-coded region 98 EU mapped to FR
- phy1 mwlwifi 2.4 GHz, hard-coded region 98 EU mapped to FR
- phy2 mwifiex 2.4 and 5 GHz, hard-coded region US
When the system boots, it detects a conflict between the user selected
region and the radios, e.g. BG FR US, and applies extreme restrictions,
preventing phy0 from starting on any DFS channel. phy2 works.
Add a device-tree flag, which allows affected devices, where the radio
conflicts with the platform to ignore the incorrect regulatory hint in
the ROM of the radio, so the platform regulatory domain can be used.
This does not allow the user to change the regulatory configuration of
any radio. It only allows phy0 to start and operate according to its
certified configuration.
