[PATCH 1/2] ath10k: Add optional qdss clk

From: Bjorn Andersson <hidden>
Date: 2019-12-23 05:49:39
Also in: linux-arm-msm, linux-devicetree, linux-wireless, lkml
Subsystem: arm/qualcomm mailing list, atheros ath generic utilities, networking drivers (wireless), open firmware and flattened device tree bindings, qualcomm atheros ath10k wireless driver, the rest · Maintainers: Jeff Johnson, Johannes Berg, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

The WiFi firmware found on sm8150 requires that the QDSS clock is
ticking in order to operate, so add an optional clock to the binding to
allow this to be specified in the sm8150 dts and add the clock to the
list of clocks in the driver.
