[PATCH 1/3] wifi: wcn36xx: add support for WCN3610

[PATCH 1/3] wifi: wcn36xx: add support for WCN3610

[Kerigan Creighton]

The WCN3610 is a 2.4GHz-only WLAN/BLE combo chip used in some
cheaper Android and Windows phones such as the Lumia 550, and
IoT devices like the Anki Vector robot. It shares a lot in
common with the WCN3620.

Tested on an Anki Vector 1.0 and 2.0 robot. Support for other
WCN36xx chips has not been affected.

The WCN3610 requires specific BTC configuration values for
stable Wi-Fi. Without these values, there's some packet loss.
An extra CFG table was made so other chips are not affected.

STA_POWERSAVE causes firmware bugs (long hangs) with the
WCN3610, thus it has been disabled just for this chip.

[PATCH 2/3] remoteproc: qcom_wcnss_iris: add support for WCN3610

[Kerigan Creighton]

Add a qcom,wcn3610 compatible string.
The WCN3610 shares the same register configuration as the
WCN3620, so its configuration is being reused.

https://www.kernel.org/doc/html/latest/devicetree/bindings/submitting-patches.html

"The Documentation/ portion of the patch should come in the series before the
code implementing the binding."

Also ideally for any multi-patch series there should be a cover letter.
