[PATCH v2 1/2] dt-bindings: net: wireless: ath11k: add ieee80211-freq-limit property

[Christian Lamparter]

This is an existing optional property that ieee80211.yaml/cfg80211
provides. It's useful to further restrict supported frequencies
for a specified device through device-tree.

[PATCH v2 2/2] wifi: ath11k: add support DT ieee80211-freq-limit

[Christian Lamparter]

The common DT property can be used to limit the available
channels/frequencies. But ath11k has to manually call
wiphy_read_of_freq_limits().

I got three similar patches in one thread, two with same versions.

One version is one patchset. Do not attach (thread) your patchsets to
some other threads (unrelated or older versions). This buries them deep
in the mailbox and might interfere with applying entire sets.

Best regards,
Krzysztof
