From 23e88135bb86361cbd4c260a1a38bb7fda2b2338 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Thu, 8 Oct 2020 23:44:20 -0700 Subject: soc/intel: Add a driver for CNVi WiFi/BT controllers This change adds a common block driver for CNVi WiFi/BT controllers in Intel SoCs. This driver uses the common PCI dev operations in addition to generating ACPI device node and returning ACPI name for the controller device. This change also selects this driver for CML, GLK, ICL, JSL and TGL.
