Subject: [PATCH] wcn36xx: Differentiate wcn3660 from wcn3620
Git-commit: 98d504a82cc75840bec8e3c6ae0e4f411921962b
Patch-mainline: v5.18-rc1
References: git-fixes
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.
