From afeb7b3f6864f74bbcf22c8744998e55db219be2 Mon Sep 17 00:00:00 2001 From: Karthikeyan Ramasubramanian Date: Thu, 23 Jul 2020 00:25:25 -0600 Subject: drivers/wifi: Adapt generic wifi driver into a chip driver Re-organize the existing generic wifi driver into a generic wifi chip driver. This allows generic wifi chip information to be added to the devicetree.
