Date: Fri, 25 Mar 2022 16:05:21 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Bryan ODonoghue <bryan.odonoghue@...aro.org>, Loic Poulain <loic.poulain@...aro.org>, Kalle Valo <quic_kvalo@...cinc.com> Subject: [PATCH 5.10 37/38] wcn36xx: Differentiate wcn3660 from wcn3620 From: Bryan O'Donoghue <bryan.odonoghue@...aro.org> commit 98d504a82cc75840bec8e3c6ae0e4f411921962b upstream. The spread of capability between the three WiFi silicon parts wcn36xx supports is: wcn3620 - 802.11 a/b/g wcn3660 - 802.11 a/b/g/n wcn3680 - 802.11 a/b/g/n/ac We currently treat wcn3660 as wcn3620 thus limiting it to 2GHz channels. Fix this regression by ensuring we differentiate between all three parts.
