[PATCH v2 2/2] wcn36xx: Add ability for wcn36xx_smd_dump_cmd_req to pass two's complement

From: Bryan O'Donoghue <bryan.odonoghue@linaro.org>
Date: 2021-09-09 14:48:02
Subsystem: atheros ath generic utilities, qualcomm wcn36xx wireless driver, the rest · Maintainers: Jeff Johnson, Loic Poulain, Linus Torvalds

Qcom documents suggest passing of negative values to the dump command,
however currently we convert from string to u32 not s32, so we cannot pass
a two's complement value to the firmware in this way.

There is in fact only one parameter which takes a two's complement value
<tigger threshold> in the antenna diversity switch command.

Downstream:
iwpriv wlan0 dump 71 3 <schedule period> <trigger threshold> <hysteresis value>

Upstream:
echo "71 3 <schedule period> <trigger threshold> <hysteresis value>" > /sys/kernel/debug/ieee80211/phy0/wcn36xx/dump

Fixes: 8e84c2582169 ("wcn36xx: mac80211 driver for Qualcomm WCN3660/WCN3680 hardware")
