Michael Yartys 67174adc94 ath10k-ct: update to 2020-01-29
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.
