You're also adding the firmware-name, but: * That's in the bindings. * The name you have there matches what's in the linux-firmware repository in commit 0d5e9f7e0aa1 ("ath11k: WCN6750 hw1.0: add to WLAN.MSL.1.0.1-00887-QCAMSLSWPLZ-1") Hmmm, I guess one question is whether this same firmware would also be used for other, non-Chrome sc7280 devices. If so then the firmware-name probably belongs straight in sc7280.dtsi? I suppose that could always happen in a future change if/when we have other sc7280 devices and it's clear that they're sharing firmware. Thus: Reviewed-by: Douglas Anderson <dianders@chromium.org> -Doug

One of our wifi engineers mentioned that his contact at QC said the FW should reside directly in /lib/firmware, not in any sub-directory, which would be odd, but up to them ;-) > Reviewed-by: Douglas Anderson <dianders@chromium.org> Thanks!

Enable the 'wifi' and 'remoteproc_wpss' nodes for all sc7280 based Chrome OS boards. Delete the corresponding entries from sc7280-idp.dtsi since this file includes sc7280-chrome-common.dtsi.
