Subject: [PATCH 1/2] ath10k: enable QCA6174/QCA9377 to read the chip temperature

From: Ryan Hsu <[email protected]>

The firmware of QCA6174/QCA9377 already support the feature, just enable
it to be able to handle the get_temperature command and process the event.

You can read the temperature by using the hwmon interface,

cat /sys/class/ieee80211/phy*/device/hwmon/hwmon2/temp1_input

Verified with the following hardware and software combination,
QCA6174, only firmware-4.bin doesn't support this, otherwise all support.
QCA9377, all the firmwares upstreamed support this command

Subject: [PATCH 2/2] ath10k: add FW API 6 firmware image for QCA9377

From: Ryan Hsu <[email protected]>

Firmware WLAN.TF.2.1-00014-QCARMSWP-1 now supports reading the board ID
information and also required 9 IRAM bank, which older ath10k version
don't have the support will fail to be enabled, so in order to maintain
the backward compatibility, we need to update the FW API to 6.
