Changes: ath10k-ct: Support better RSSI measurements. When used with recent firmware, these changes allow the driver to query per-chain noise-floor from the radio to better calculate the per-chain RSSI. The per-chain RSSI is then summed to provide the 'combined RSSI'. This gives better per-chain RSSI as well as combined RSSI, especially when running with more than 20Mhz bandwidths. Refresh patches.

Subject: [PATCH] ath10k: Limit available channels via DT ieee80211-freq-limit
|
|
|
|
Tri-band devices (1x 2.4GHz + 2x 5GHz) often incorporate special filters in
|
|
the RX and TX path. These filtered channel can in theory still be used by
|
|
the hardware but the signal strength is reduced so much that it makes no
|
|
sense.
|
|
|
|
There is already a DT property to limit the available channels but ath10k
|
|
has to manually call this functionality to limit the currrently set wiphy
|
|
channels further.
