[PATCH v3 0/2] dt-bindings: convert mt76 and ieee80211 in yaml

[PATCH v3 0/2] dt-bindings: convert mt76 and ieee80211 in yaml

[Lorenzo Bianconi]

Convert mt76 and ieee802111 dts bindings from .txt to .yaml

Changes since v2:
- add myself as ieee80211.yaml maintainer
- add Ryder as mt76.yaml maintainer
- fix led node in mt76.yaml
- fix ieee80211.yaml refernce in mt76.yaml
- fix ieee80211-freq-limit property in ieee80211.yaml

Changes since v1:
- introduce ieee80211.yaml bindings
- remove unnecessary properties in mt76.yaml

-	used for devices that in a given config support less channels than
-	normally. It may happen chipset supports a wide wireless band but it is

-- mediatek,eeprom-merge-otp: Merge EEPROM data with OTP data. Can be used on

Drop the $ref.

Just 'ieee80211-freq-limit: true' unless there are some constraints you 
can define like how many entries.

That's not how this property is defined. It applied to how 'reg' is 
accessed. But I guess it's already used...

'additionalProperties: false' should work here and is a bit stricter.
